ノード Signals are tagged as a point on the track. So it is clear which track they belong to. It is recommended to see country-specific tagging to use the specific tagging scheme for your country.

Important Hint: If a signal is tagged between two OSM-ways, both ways have to have the same direction. So it is possible for applications to detect the correct position.

Key Value Property Description Default value
Note: Disused and abandoned signals can be mapped by adding disused: or abandoned:. (Example: disused:railway=signal).
railway signal signal a signal
ref <signal designation> signal designation The name or designation of a signal.
railway:position <distance value, such as 40.6> distance The rounded distance position of a signal. If using miles, prefix the number with mi:.
railway:position:exact <distance value, such as 40.625> exact distance The exact (three-place) distance position of a signal. If using miles, prefix the number with mi:.
railway:signal:position left/right/bridge/overhead/in_track location Indicates the location of the signal in references to the track. bridge means the signal is located on a signal gantry overhead the track. left or right determines on which side of the track the signal is located in reference to the way direction in OpenStreetMap. overhead means a signal is attached to the catenary and in_track is intended for signals in the midle of the track - such as one attached to a buffer stop.
railway:signal:direction forward/backward/both direction of displaying Determines how you have to drive to have a view on the signal. Values are in reference to way direction in OpenStreetMap.
railway:signal:catenary_mast yes/no catenary mast Is the signal attached to a catenary mast?

These tags really only describe a single signal location. The tags below can be used to specify what type of signal it is:

The tagging scheme for signals is designed to use as few tags as possible.

The tag structure for signals is as follows:


for the exact type of signal. CATEGORY is a signal categorie (e.g. main, speed, distant, …) of the table below. TYPE is the country-specific name of the signal or the abbreviation. When unknown, even yes can be entered, with more specific tagging being preferred. To prevent ambiguities, the code should be prefixed with a country code according to ISO 3166-2 (e.g.: US:<name>). If no uniform naming system is in place in a country, the generic name for this signal should be used in lowercase. Example: railway:signal:main=AT:hauptsignal, railway:signal:main=DE:hp, or railway:signal:main=US:main.

You can add detailed properties of the signal by tags following this scheme:


PROPERTY is a predefined property of the table below.

List of signal categories:

Type Name Description
main Main signal A signal that gives the permission to enter a station, leave a station or enter the next block section of a track. A main signal controls mainline and shunting movements and indicates the clearness of a track up to the next signal.
main_repeated Duplicated signal A signal to indicate the state of the main signal. Not to be confused with a Distant signal.
distant Distant signal A distant signal is placed at braking distance from a main/combined signal and indicates the aspect of the following signal to ensure that a train can stop before reaching the main/combined signal.
minor Minor signal A signal with a lower priority than main signal. In most cases they are used inside stations to protect occupied sections or control low speed (shunting) movements. It does not require any distant signal and applies to both mainline and shunting movements.
minor_distant Minor Distant signal A Distant signal for Minor signals.
combined Combined signal A signal that combines the function of a main and a distant signal. It indicates the state of the next two block sections and is valid for all train movements.
shunting Shunting signal A signal that controls low speed shunting movements inside stations. It does not apply to mainline movements.
crossing Level crossing signal A signal that indicates that the technical equipment (lights, barriers, bells) of a level crossing is active to warn automobile drivers about an approaching train.
crossing_distant Level crossing distant signal A signal which notifies the train driver to attend a level signal which will follow.
crossing_info Level crossing marker board A signal which describes the level crossing. It is usually mounted next to the level crossing and shows information like the current position (kilometre/miles) or the crossing number.
crossing_hint Level crossing announcement board A signal which notifies about a level crossing he will reach soon.
electricity Catenary signal A signal for electric locomotives indicating when and where the pantograph or other collector needs to be lowered. (e.g.: between different electrical systems.)
humping Hump yard signal This signal controls the speed of locomotives pushing cars towards the hump.
speed_limit Speed Limit indicator A signal that displays the maximum permissible speed in a track section.
speed_limit_distant Distant Speed Limit indicator A signal indicating an upcoming speed limit change.
whistle Horn signal A signal indicating the operator should use the horn.
ring Bell signal A signal indicating the operator should use the bell.
route Route indicator A signal that indicates the set up route.
route_distant Route Change Distant A signal indicating an upcoming route indicator.
wrong_road Wrong Road signal A signal indicating the movement to a track that normally would have traffic in the oncoming direction.
stop Stop post / Stop Board In general, this signal marks a position on a track, where a train needs to stop. In most cases it indicates the position where a passenger train should stop at a platform. On branch lines with simplified operational rules, this signal may also be used to mark a position where a train has to stop to wait for a permission to proceed.
stop_demand Stop-on-demand indicator A signal at small halts that is operated by waiting passengers to visualize their demand for a stop of the next train.
station_distant Upcoming Station A signal indicating an upcoming station.
radio Radio Change A signal providing instructions on radio usage.
departure Departure signal A signal indicating that a passenger train is ready to leave the station.
resetting_switch Resetting Switch signal A signal indicating the status of a resetting switch.
resetting_switch_distant Resetting Switch Distant A signal indicating an upcoming resetting switch.
snowplow Snowplow signal A signal that give instructions to vehicles with a snowplow. In most cases they are placed to warn the crew to raise the snowplow to avoid hitting any obstructions such as level crossings or bridges.
short_route Short entry indicator A signal which shows the train driver that he has to stop earlier than usual (usual = exit signal). Used if the train drives into a dead-end signal or joins another train.
brake_test Signal used for break tests This signal supports the communication between the train driver and the personnel checking the breaks.
fouling_point Clear-of-points marker/Track contact marker A signal that indicates up to which limit a track may be occupied to avoid collisions and malfunctions of signals and switches.
helper_engine Signals related to helper engines A signal giving instructions for helper engines at steep railroad lines (e.g. in mountain areas).
train_protection Signals related with train protection system topics Signals of this category show beginning/end of railway sections with a specific or any train protection system. This category also covers the signals (usually signs) mounted along railway lines with cab signalling. This section has been replacing the old sections lzb and lzb_start since 2014.
steam_locomotive Signals related to steam locomotives Signals that give instructions to the staff of steam locomotives.

List of signal properties:

Property Name Description
form Display/Style The physical format of the signal: (semaphore), (light) or (sign).
deactivated Signal Activity Is the signal still operational? Either (yes) or (no).
height Signal Height Height design of signal: either (dwarf) or (normal). Alternatively, you can specify the exact height measurement.
states Signal Aspects For variable signals, a list of possible signal aspects, each separated by a semicolon (e.g.: clear;aproach_limited;limited_clear;approach_medium;...).
shortened Shortened Braking Distance Is the signal placed closer than usual to the next signal? Either (yes or no).
repeated Repeater signal When a main/combined signal is not visible from distance (e.g. because of track curves), a repeater is installed to repeat the aspect of the main/combined signal. Use yes to mark these signals, otherwise use no or omit this tag.
frequency Frequency When activated, the frequency reading of the signal in Hertz (Hz).
voltage Voltage When activated, the voltage reading of the signal in Volts (V).
speed Signal Speed The displayed signal speed in Kilometers/Hour. For values in Miles/Hour, it is necessary to prefix it with mph.
function Signal Function The exact function of the signal, such as an Entry Signal (entry), Exit Signal (exit), Block Signal (block) or Intermediate Signal (intermediate). In the past, the deprecated value between was used for intermediate signals.
caption Additional Text Additional text specified on a signal. This tag was merged with the deprecated description, which was in use until 2014.
marker_light Marker Light Does the signal have a special light to show that it temporarily is invalid? Either (yes or no). Deprecated and moved to DE:OpenRailwayMap/Tagging in Germany.
only_transit Valid only for Passing Trains Does the signal only apply to trains that go through the following breakpoint/station? Either (yes) or (no).
substitute_signal Substitute Signal A signal added to another signal, and indicates the behaviour in cases of failures of the actual signal. Also known as caution signal. For example the train may pass the signal at low speed and must be prepared to stop at any obstacle. Either (yes) or (no).
twice Double Signal Is the signal instruction to be carried out twice? Either (yes or no).
type Subtype or order The subtype of a signal or what has to be down at/after this signal.
for Vehicle type Specifies for which types of vehicles this signal is valid. This can be multiple units (multiple_unit) or locomotives (locomotive). This tag can also be used for specifying locomotive classes or the type of traction (steam, diesel, electric, ...).

For specific tagging of certain signals in a specific country, refer to the Country-specific tagging section. These pages are currently a work-in-progress.
