This article is about at-grade intersections between railroad and road. For where two rail lines cross, see level junction. For a type of nuclear receptor (RXR), see Retinoid X receptor.
A level crossing is an intersection where a railway line crosses a road or path at the same level, as opposed to the railway line crossing over or under using a bridge or tunnel. The term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing,grade crossing,road through railroad, railroad crossing, train crossing, and RXR (abbreviated).
The history of level crossings depends on the location, but often early level crossings had a flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Gated crossings became commonplace in many areas, as they protected the railway from people trespassing and livestock, and they protected the users of the crossing when closed by the signalman/gateman. In the second quarter of the 20th century, manual or electrical closable gates that barricaded the roadway started to be introduced, intended to be a complete barrier against intrusion of any road traffic onto the railway. Automatic crossings are now commonplace in some countries as motor vehicles replaced horse-drawn vehicles and the need for animal protection diminished with time. Full, half or no barrier crossings superseded gated crossings, although crossings of older types can still be found in places. New technology is advancing to create new ways of protecting the railway from users of a level crossing, with one of the most recent being obstacle detection scanners fitted to some crossings in Europe.
Some international rules have helped to harmonize level crossing. For instance, the 1968 Vienne convention about signalisation routière:
- in its Chapitre III Signaux lumineux de circulation: Article 23b stand that one or two blinking red fire indicates a car should stop, when if they are yellow the car can pass with caution.
This has been implemented in many countries, including countries not being part of the Vienna Convention.
- in its article 27, a stop line is suggested at grade crossing
- article 33, 34, 35 and 36 are specific to level crossing, because level crossing are recognized as dangerous
- article 35 indicates a cross should exist when there is no barrier
Modern trains have a much larger mass relative to their braking capability, and thus a far longer braking distance than road vehicles. With rare exceptions, trains do not stop at level crossings and rely on vehicles and pedestrians to clear the tracks in advance.
Level crossings constitute a significant safety concern internationally. On average, each year around 400 people in the European Union and over 300 in the United States are killed in level crossing accidents. Collisions can occur with vehicles as well as pedestrians; pedestrian collisions are more likely to result in a fatality. Among pedestrians, young people (5–19 years), older people (60 years and over) and males are considered to be high risk users.
As far as warning systems for road users are concerned, level crossings either have "passive" protection, in the form of various types of warning signs, or "active" protection, using automatic warning devices such as flashing lights, warning tones and barriers or gates. Fewer collisions take place at level crossings with active warning systems. Modern radar sensor systems can detect if level crossings are free of obstructions as trains approach. These improve safety by not lowering crossing barriers that may trap vehicles or pedestrians on the tracks, while signalling trains to brake until the obstruction clears (however, they cannot prevent a vehicle from moving out onto the track once it's far too late for the locomotive to slow even slightly).
At railway stations, a pedestrian level crossing is sometimes provided to allow passengers to reach other platforms in the absence of an underpass or bridge, or for disabled access. Where third rail systems have level crossings, there is a gap in the third rail over the level crossing, but this does not interrupt the power supply to trains since they have current collectors on multiple cars.

Traffic signal preemption
See also: Traffic signal preemption
Traffic signal-controlled intersections next to level crossings on at least one of the roads in the intersection usually feature traffic signal preemption. Approaching trains activate a routine where, before the train signals and gates are activated, all traffic signal phases go to red, except for the signal immediately after the train crossing, which turns green (or flashing yellow) to allow traffic on the tracks to clear (in some cases, there are auxiliary traffic signals prior to the railroad crossing which will turn red, keeping new traffic from crossing the tracks. This is in addition to the flashing lights on the crossing gates). After enough time to clear the crossing, the signal will turn. The crossing lights may begin flashing and the gates lower immediately, or this might be delayed until after the traffic light turns red.
The operation of a traffic signal while a train is present may differ from municipality to municipality. In some areas, all directions will flash red, turning the intersection into an all-way stop. In other areas, the traffic parallel to the railroad track will have a flashing yellow for the duration of the train while the other directions face a flashing red light for the duration of the train. Still in other areas, the traffic parallel to the railroad track will have a green light for the duration of the train while the other directions face a red light for the duration of the train.
Crossings around the world
This section needs expansion with:
In European union (including UK), 47% are Passive (unprotected) level crossings and 53% are Active (protected) level crossings. Level crossing fatalities are 28% of railway fatalities.
Albanian level crossings are uncommon, but do have red lights and barriers that may be automatic. Many crossings are still manual in Albania, but some are automatic and have bells. There are not many crossings in Albania [citations needed. How many? Where in Albania are they?]
Austrian level crossings are similar to German crossings, in that they have either a single or double light with automatic barriers that lower when a train approaches. The crossings with two lights (one amber, one red) is the more modern, replacing old single red light crossings.
Automatic level crossings in Belgium have two red lights, a "moon-white" light, electronic (previously mechanical) bells and (usually) barriers. The white light flashes for half a second at regular intervals to inform drivers and pedestrians that they can cross the level crossing, and that the signal is in working order. In some cases the white light is absent; the Belgian traffic law of 1975 does not cover that situation. The bells ring until the barriers are fully lowered and then stop. If barriers are absent the bell continues ringing throughout.
At a level crossing, any overhead electric power cables must also cross. This led to a conflict where a mainline railway that crossed one of the country's once extensive interurban tram lines (vicinal, buurtspoorweg/vicinaux) was electrified. In at least one location, this led to the tram overhead being dismantled.
A level crossing in Bulgaria usually has two red lights and a flashing white light, similar to Belgian crossings. Automatic barriers protect the crossing and the white light informs correct operation, although older crossings omit the white light.
Croatian level crossings are similar to Slovenian crossings in that the lights are composed of to red lights in a triangle. Many crossings are automatic with barriers and bells.
Level crossings in Czech Republic use a sign on the lights that reads "Pozor Vlak" (Attention - Train) to warn people of the crossing. The lights are similar to the Belgian crossings in that they have two red lights and sometimes a white light, with half barriers. On some crossings, the space for a white light is provided but no light is there.[why?] Usually a yellow outline surrounds the crossbucks for increased visibility during the night.
In Finland, level crossings with warning lights have the more common red light(s) and a white light that flashes except when the red light(s) flash. Most, but not all, crossings with lights also have barriers. Full-length barriers are usually used only for pedestrian and bicycle lanes. Half-length barriers are used for motor roads, to avoid the risk of a vehicle being trapped on the tracks between the barriers. Bells begin to ring when the red lights start flashing and usually stop when the barriers have come down. Red-and-yellow crossbuck is used on both controlled and uncontrolled level crossings. If there are two or more tracks, the lower part of the cross is doubled. Only minor agricultural crossings might have no signs at all. On bigger roads there are usually also approach signs as seen in the picture. Finnish level crossings are the sixth safest in Europe. Finland's state railway system has almost 3000 level crossings, according to TraFi. In Finland over the course of railway history many level crossing accidents have occurred, in comparison to other Scandinavian countries. In Finland the maximum speed for trains on the rails with level crossings is 140 km/h.
French level crossings usually have a single red light on a circle backboard, bells and automatic half barriers. When activated, the red light flashes, the bells ring, and the barriers come down. French level crossings with more than one track have a sign saying "un train peut en cacher un autre" (a train can hide another train).
As of 2016 France has 15,459 level crossings (by comparison, there were 33,500 in 1938 and 25,000 in 1980). Of these, less than 0.4% are on national roads, 31.4% are on departmental roads and 68.2% are on town roads. The high-speed train lines are built with no level crossings, but high-speed trains are also used on classical railway lines and exposed there to level crossing accidents.
154 out of 15459 level crossings are registered in a national program to make level crossings more secure.
In 2015, 100 crashes occurred at French level crossings, causing 26 fatalities. These crashes are usually caused by imprudence, e.g., trying to pass as the barriers are down or are closing, in violation of the French traffic code.
Level crossings in Germany are different than some other level crossings throughout Europe. These crossings use yellow and red lights and a bell/alarm (some crossings do not have these though) to indicate that the crossing is active. When activating a preliminary yellow light flashes which is followed by a red light that stays lit until the train(s) have cleared the crossing. Most of these crossings usually have a lightning symbol on the crossbucks. These symbols indicate that the railway is electrified with overhead wires. Older crossings have a single red light on a square backboard with a red and white boarder. After crossing the level crossing, unless there is a speed limit sign, the speed limit is the national speed limit. That is, 50 km/h for built up areas and 100 km/h outside built up areas.
In Hungary, level crossings mostly do not have audible tones, and some also do not have lights. Full barriers usually don't have lights, but have an audible warning. Crossings equipped with lights are common. The newest, and best solution is a crossing equipped with half-barriers and LED-lights. A unique type of level crossings in Hungary have a sign saying "10 percen túl is zárva tartható" (can be kept closed for more than 10 minutes).
Irish level crossings are similar to UK level crossings, in the fact that they have a preliminary amber light before the red lights start flashing and the barriers descend (one example at Wexford does not have an amber light). Crossings are the same on the whole island of Ireland, and are either of the old gated variant, or are automatic. Ireland does have automatic crossings that have full barriers, which are not seen in the UK. The audible alarms are unique to the country.
Level crossings in Italy, much as in the rest of Europe, can be manned, unmanned, manual, or automated. In the Italian highway code, level crossings are called Passaggi a Livello, often abbreviated to "P/L" on vertical and horizontal road signage. Some level crossings have a sign saying "stop con segnale rosso" (stop with red signal). The crossing can be composed of single or double red lights, mechanical or electrical barriers and sometimes a rotating crossbuck.
Most level crossings have half barriers, mechanical or electrical bells, and double (or sometimes single) red lights. The lights flash alternately, as do the ones on the barriers. Those for pedestrians with an active warning system have full barriers. Three level crossings are operated remotely by staff from a traffic control center, using cameras; these have full barriers and no bells. Two level crossings for vehicles have full barriers, with a system to detect a vehicle been trapped; in this case the exit barriers are opened. Crossings with little road traffic and/or little rail traffic have no alarm, just warning signs. There are no level crossings where trains routinely run at over 140 km/h. Level crossings have a sign saying "WACHT" (WAIT).
Warning lights and bells are activated when the train is about 1 km before the crossing, depending on line speed. 5 seconds later the barriers start closing, which takes about 10 seconds. When the barriers have closed, the bells are often set less loud. Lights and bells are stopped when the barriers have raised again. As passive warning signs there are red and white striped fences, red and white saltires for single tracks (doubled in case of two or more tracks) and sometimes advanced warning signs at 80, 160 and 240 metres.
When there is a station shortly before the level crossing and an intervening signal, the signal may remain red and the crossing open when the train approaches the station. Only after some time the crossing closes, after which the signal is pulled.
In Norway, level crossings have red and white crosses with a similar light system to German crossings, although the yellow light shines and then the single red light flashes, as do the lights on the barriers.
From 1998-2008 the Norwegian rail administration (Jernbaneverket) removed about 1000 level crossings, leaving about 3500 still in use. 160 kilometres per hour (99 mph) is the maximum speed for trains over level crossings. In addition, Oslo's and Bergen's tram or light rail systems have some level crossings. Most lines on Oslo's metro (T-banen) are free of them. Most of the level crossings were removed from the old suburban railways in the western parts of the city, when the lines were upgraded to metro standard, but some crossings are retained on the Holmenkollen Line.
Portugal's level crossings have bells, but most do not have lights. Two alternating flashing lights accompany the barriers, which can be manual or automatic. They also have a sign saying "pare ao sinal vermelho" (stop at the red light). When activated, the bells ring, the lights flash, the barriers come down and the bells continue to ring.
Romania's level crossings have a light pattern similar to the Czech Republic and Russia, but the lights have a different appearance. The sequence is the same with the alternating red flashing lights and the intermittent white light that flashes when no trains are approaching.
Moldova's level crossings are very similar to Russian level crossings, with the 2 red lights, but, like the Romanian level crossings, have an intermittent white light that flashes when there are no trains approaching. The bells are very loud, just like Russian bells.
Russia's level crossings have one of the loudest bells. Like U.S. level crossings, Russia has 2 red lights. It acts similar to U.S. level crossings, but the barriers go slightly up for 1 second before going down.
Serbian level crossings have red triangles with a yellow inside, and two red lights in the triangle. Alarms sound, the barriers come down and the lights flash when a train approaches. The crossing barriers and crossbucks are red and yellow.
In Slovenia, level crossings are similar to Swiss crossings, as in they have a normal warning sign triangle but with two red lights inside it. The crossings have half barriers (mainly) and alarms that sound when a train approaches.
Spanish level crossings have two alternating red lights and sometimes a pedestrian light on the other side of the crossing. When activated, the lights flash, the bells ring and the barriers lower, as the crossing is usually automatic. More rarely, once the barriers have fully lowered, the sound changes. For some level crossings, when the barriers begin to go up, the square light stops flashing. More often, the level crossings in Spain, unlike all other level crossings, activate a long time before the train arrives.
In Sweden there are 8,500 level crossings, according to Trafikverket, the Swedish Transport Administration (former Banverket, Swedish Rail Administration). On public roads they have light signals with or without gates. On private roads there are level crossings without signals. Most accidents occur on crossings without gates. For many years there have been activities to reduce the number of accidents, usually by adding gates, or adding light signals if there were none. On the main lines many bridges have been built, and also anywhere a new road or new railway has been built. Still there are some level crossings left on the main lines. A train speed of 200 km/h is allowed in Sweden over level crossings, if there are gates and an obstacle detection unit. This unit detects cars on the track and prevents the gates from closing fully and stops the train. According to Trafikverket in 15 years there has only been one serious collision between a car and a train on such a level crossing, when a car ran through the gates just in front of the train. Level crossings have a power line with a sign saying "livsfarlig ledning" (dangerous conduit). Some also have a sign saying "se upp för tåg" (beware of trains)
Most level crossings in Switzerland have two red lights on the bottom of a triangle backboard, bells, barriers, and more rarely, another triangle with one red light in the middle. When activated, each red light flashes for a third of a second. The bells ring as well. After a few seconds, the barriers come down and the bells stop ringing. Most Swiss crossings are automatic and a few are also on rack railway systems, so they have rising teeth that come out from the ground.
Turkish level crossings have two red lights, alarms, barriers and a single red light displaying "DUR" (stop).
Level crossings in Ukraine can consist of two red lights and possibly a white light to indicate the crossing is in working order. Barriers can also be included, as well as a vast array of noises that accompany the closure.
Main article: Level crossings in the United Kingdom
Level crossings in the United Kingdom started out as manually gated crossings opened by a signalman. These were standard all across the network until mechanised barriers started to be introduced. These could be operated by a signalman adjacent to the crossing or were automatic. After the major Hixon rail crash in 1968, the design of level crossings started to change, and all mechanised crossings had to have a preliminary amber light fitted, which makes UK level crossings one of only a few countries with this design of crossing. More recent advantages in technology have led to more technical automatic crossings, more safer open crossings, and crossings with obstacle detection systems to detect stray people or vehicles on the crossing.
Many crossings in the country now are composed of lights, alarms and full, half or no barriers. The lights are unique in that they have a preliminary amber light accompanied by two red lights. The alarms come in a range of tones, and can be composed of a speaking warning saying "warning: another train is approaching". Many crossings are automatic, but can be manually operated or by CCTV or obstacle detection. There are some gated crossings still left in the country, as well as some open crossings with no lights, barriers or alarms. There are various classifications for crossings in the UK.
Grade crossings in Canada are required by law to be marked by a crossbuck with alternating flashing red lights and gate arms. Crossbuck signs of an image of a track are white with a red outline and contain a supplemental sign to indicate the number of tracks, and has the number and track image in either red (usually for CN rail lines) or black (for CP rail lines). The advance-warning sign, which is a yellow diamond shape with a diagram of a track crossing a straight segment of road (similar to a crossroads sign, except that the horizontal road is replaced by a track). Before changes in regulations mandated bilingual (English and French) or no-wording signs, crossbucks contained the words "Railway Crossing" or "Traverse de Chemin de fer" instead of "Railroad Crossing."
Mexico has also begun to install US-style crossing signals on some of its KCS de Mexico, Ferromex, & Ferrosur rail lines; however the majority of rail crossings in Mexico remain unsignalled, marked only with a crossbuck. The crossing devices are very similar to the US models, sporting larger lights. The crossbucks read "Cruce de ferrocarril", "Crucero ferrocarril", or "Cuidado con el tren". The majority of crossings are solar operated, and the lights flash faster than the US signals. Unfortunately, these devices are easy targets for vandals as they steal their components such as gate motors and solar panels. In many cases the gates do not lower due to vandalism or lack of maintenance. In some cases due to the lack of maintenance, the lights do not turn on at all. The rail companies, which by law are required to maintain the crossing signals, take little to no action in maintaining these devices, and the majority remain unmaintained, posing a threat to drivers.
The first US patent for manual/electrical crossing gates was awarded on 27 August 1867, to J. Nason and J. F. Wilson, both of Boston.
Every crossing, whether above grade, below grade, or at grade, is required to be assigned a unique identifier which is a six-digit number and a trailing letter used as a checksum. This identifier is called a Grade Crossing Number, and is usually posted with a sign or sticker on the sign or equipment. This allows a particular crossing anywhere in the United States to be precisely identified as to its exact location in the event of an incident involving that crossing.
Traffic control devices
All public crossings in the United States are required to be marked by at least a crossbuck. The 2009 Manual on Uniform Traffic Control Devices requires passive crossings (crossings without actuated flashing lights or gates) to have either stop signs or yield signs in addition to the crossbuck, unless a flagger will stop traffic every time a train approaches. Normally a yield sign is used, unless it is determined that all vehicles should stop at the crossing, such as a location with poor sight distance. All passive crossings must be upgraded to meet this standard by December 31, 2019.
If the crossing has more than one railroad track, the crossbuck is required to have a small sign beneath it denoting the number of tracks.
As traffic on the road crossing or the rail crossing increases, safety features are increased accordingly. More heavily trafficked crossings have "automatic warning devices" (AWDs), with alternately flashing red lights to warn automobile drivers and a bell to warn pedestrians. Additional safety is attained through crossing gates that block automobiles' approach to the tracks when activated. Increasingly, crossings are being fitted with four-quadrant gates to prevent circumventing the gates.
Operation of a typical AWD-equipped railroad crossing in the United States is as follows:
- About 30 seconds before arriving at the crossing, the train trips a track circuit near the crossing, triggering the crossing signals. The lights begin to flash alternately, and a bell (or bells) mounted at the crossing begins ringing. After several seconds of flashing lights and ringing bells, the crossing gates (if equipped) begin to lower, which usually takes 5–10 seconds. Some AWDs silence the bell once the gates are fully lowered (typically seen on most Norfolk Southern and CSX crossings); most continue ringing the bells throughout (Union Pacific, BNSF Railway). Some crossings will not sound the bell at all after dark in the case that it is installed near a residential area. The lights continue to flash throughout regardless.
- About 15–20 seconds before arriving at the crossing, the train begins ringing its bell and sounding its horn in accordance with NORAC rule 14L or GCOR rule 5.8.2(7): two longs, one short, and one long. These are prolonged or repeated until the engine occupies the crossing. If the AWD is equipped with a wayside horn in accordance with FRA Quiet Zone rules, the AWD may provide the whistle signal instead of the train; however, the train is required to ring its bell regardless.
- After the train has cleared the crossing, the bells (if silenced) may begin ringing again (such as the Florida East Coast Railway), and the gates (if equipped) begin to rise. Once the gates have completely risen back to their fully raised position, all warning signals, including the lights and bells, are suppressed.
Some AWD track circuits are equipped with motion detectors that deactivate the crossing signal if the train stops or slows significantly before arriving at the crossing.
As indicated above, the pattern of the bells at each individual crossing can be different. (These bells should not be confused with the bells that are mounted on the trains.) Generally, the bells follow one of these patterns:
- The bell begins ringing when the lights begin flashing and stops when the gates have completely lowered.
- The bell begins ringing when the lights begin flashing and stops when the gates begin to go up following the passing of the train.
- The bell begins ringing when the lights begin flashing and stops when the gates have completely lowered, and then resumes ringing when the gates begin to go up, until the gates have returned to their original position.
- The final, and most common, practice is for the bells to begin ringing when the lights begin flashing and continue until the gates have gone up after the train passes.
Some level crossings that are located close to intersections with traffic lights program the signals with a preemption sequence so when the approaching train trips the track circuit, it not only activates the crossing signals, but also changes the traffic lights facing the crossing to green, to clear any traffic that may be queued on the crossing. If the intersection's stop line is right before the tracks (typically sharing the crossing's stop line), the track circuits would change the traffic lights to red (often without a yellow phase). Some track circuits place the signals into flash mode the entire time the AWDs are active. In cases where railroads share the right of way with vehicular traffic, simple railroad preemption may cause an all-red flash in traffic lights.
A few level crossings still use wigwag signals, which were developed in the early 1900s by the Pacific Electric Railwayinterurban system in the Los Angeles region to protect its many level crossings. Though now considered to be antique, around 100 such signals are still in use, almost all on branch lines. By law, these signals must be replaced by the now-standard alternating red lights when they are retired.
US Federal Railroad Administration regulations restrict trains to a maximum speed of 110 mph (177 km/h) at standard grade crossings. Crossings are permitted up to 125 mph (201 km/h) only if an "impenetrable barrier" is in place to block traffic when a train approaches. Crossings are prohibited at speeds in excess of 125 mph (201 km/h).
A track that will run high-speed trains in excess of 120 miles per hour (190 km/h) is being tested in Illinois between Chicago and St. Louis, Missouri. Here, due to the high speed of the trains, gates that totally prevent road traffic from reaching the tracks are mandatory on all level crossings. Steel mesh nets were tested on some crossings to further prevent collisions, but these were removed because of maintenance issues in 2001.
A new device called "StopGate" has been installed at four locations, one in Madison, Wisconsin; another in Monroe, Wisconsin and two in Santa Clara, California (on a light rail system). This system resembles a fortified version of a standard crossing gate, with two larger arms blocking the entire width of the roadway and locking into a securing device on the side of the road opposite the gate pivot mechanism. The gate arms are reinforced with high-strength steel cable, which helps the gate absorb the impact of a vehicle attempting to crash through the gate. The manufacturer claims that the StopGate can stop a 2,000 kilograms (4,400 lb) truck within 13 feet (4.0 m). Already the system has been tested at the Madison crossing, when the system stopped a truck while a Wisconsin and Southern Railroad train was in the crossing.
Another new type of barrier is being tested in Michigan that is hoped will reduce the number of times drivers attempt to drive around lowered crossing gates. The new devices are called "delineators" consisting of a series of flexible bollards that raise vertically out of vertical tubes in the pavement when the crossing signal is activated. The delineators are designed so that they will not be broken and will not damage vehicles if they are hit, allowing vehicles to exit the level crossing if they are already within it when the gates are activated. The test period for the new barrier began on 5 December 2007, and ran for at least a period of 17 months.[needs update]
In the United States and in countries following United States practices, a locomotive must have a bright headlight and ditch lights (two lights located below the headlight), a working bell, and a whistle or horn that must be sounded four times (long-long-short-long), similar to the signal for the International Morse Code letter "Q", as the train approaches the crossing.
Some American cities, in the interest of noise abatement, have passed laws prohibiting the sounding of bells and whistles. In December 2003 the US Federal Railroad Administration published regulations that would create areas where train horns could be silenced, provided that certain safety measures were put in place, such as concrete barriers preventing drivers from circumventing the gates or automatic whistles (also called Wayside horns) mounted at the crossing (which reduce noise pollution to nearby neighborhoods). Implementation of the new "Quiet Zone" Final Rule was delayed repeatedly but was finally implemented in the summer of 2005. Rail "Quiet Zone" crossings still require bells as part of the AWDs in addition to the wayside horns. Wayside horns are sets of speakers that are mounted on a pole and directed at the crossing. They produce sounds similar to a train horn.
INCOFER has crossings with crossbucks as in the photo, with the words "Cuidado con el tren" (be careful of the train), as well as crossbucks without lettering, and a normal stop sign (alto). Since most crossings don't have automatic gates, the train has to blow the horn. Some crossings have warning lights.
