OpenRailwayMap/Tagging in France
Signalling
All railway signals have the following tags:
- railway:signal:direction=(forward/backward) according to the direction of the way.
- railway:signal:position=(left/right) according to the direction of the way.
- railway:position:exact=365.913 where 365.913 is an example.
If there are multiple signals or signs at a given position, include the ref:*=* tags that apply to specify the unique identifier of each of them.

Speed Limits
Speed limits are signaled by speed indicators. They are called Tableau Indicateur de Vitesse (TIV) in French; TIVs can be either fixed or mobile.
Mobile Speed Indicators
Turnouts that can only be crossed at reduced speed in the thrown direction (approximately 60 km/h) are typically preceded by two mobile TIVs: a diamond-shaped TIV à Distance (TIV-D) followed by a speed limit reminder or TIV de Rappel (TIV-R).
- railway:signal:speed_limit_distant=FR:TIV-D
- railway:signal:speed_limit_distant:form=(sign/light)
- railway:signal:speed_limit_distant:speed=*
- railway:signal:speed_limit_distant:mobile=yes
- railway:crocodile=yes (if equipped with crocodile)
- ref:railway:signal:speed_limit_distant=*: signal identifier (optional)
The TIV-R is always paired with the Carré signal preceding the turnout.
- railway:signal:speed_limit_reminder=FR:TIV-R
- railway:signal:speed_limit_reminder:form=(sign/light)
- railway:signal:speed_limit_reminder:speed=*
- railway:signal:speed_limit_distant:mobile=yes (optional)
- ref:railway:signal:speed_limit_reminder=*: signal identifier (optional)
Additionally, if necessary, the location of the point (or the first point in the case of successive turnouts) is identified by a downwards pointing Chevron.
- railway:signal:speed_limit=FR:Chevron
- railway:signal:speed_limit:form=sign
- railway:signal:speed_limit:pointing=downwards (optional; downwards by default)
- ref:railway:signal:speed_limit=*: signal identifier (optional)
Fixed Distant Speed Indicators (Ordinary Type)
Fixed distant speed indicators of ordinary type (or TIV fixes à distance du type ordinaire in French) are usually square in shape. They are diamond-shaped when the speed limit is less than or equal to 40 km/h.
- railway:signal:speed_limit_distant=FR:TIV-D
- railway:signal:speed_limit_distant:form=(sign/light)
- railway:signal:speed_limit_distant:speed=*
- ref:railway:signal:speed_limit_distant=*: signal identifier (optional)
- railway:crocodile=yes (if equipped with crocodile)
The Z sign (pancarte) is the execution signal indicating the start of the zone to be traveled at limited speed.
- railway:signal:speed_limit=FR:Z
- railway:signal:speed_limit:form=sign
- ref:railway:signal:speed_limit=*: signal identifier (optional)
The R sign (pancarte) indicates the end of the zone where the speed limit is required and the return to normal speed (Reprise de vitesse).
- railway:signal:speed_limit=FR:R
- railway:signal:speed_limit:form=sign
- railway:signal:speed_limit:speed=none
- ref:railway:signal:speed_limit=*: signal identifier (optional)
Fixed Distant Speed Indicators (Type B)
Fixed distant speed indicators of type B (TIV-D_B) indicate that the speed limit must be observed by trains authorized to travel at speeds greater than 140 km/h. When only TIV-D_B signals are present, the speed limit also applies to self-propelled trains (automoteurs).
- railway:signal:speed_limit_distant=FR:TIV-D_B
- railway:signal:speed_limit_distant:form=sign
- railway:signal:speed_limit_distant:speed=*
- ref:railway:signal:speed_limit_distant=*: signal identifier (optional)
Fixed Distant Speed Indicators (Type C)
Fixed distant speed indicators of type C (TIV-D_C) exclusively apply to self-propelled trains (automoteurs). When a TIV-D_B is supplemented with a TIV-D_C, the speed limit indicated by the TIV-D_B only applies to trains authorized to travel at speeds greater than 140 km/h. The TIV-D_C serves as a reminder of the upstream speed limit observed by self-propelled trains.
- railway:signal:speed_limit_distant=FR:TIV-D_C
- railway:signal:speed_limit_distant:form=sign
- railway:signal:speed_limit_distant:speed=*
- ref:railway:signal:speed_limit_distant=*: signal identifier (optional)
Speed Limit Announcement (P sign)
The P sign (tableau) announces a distant speed indicator (TIV-D) for lines equipped with pre-announcement signalling. This sign is lit at night.
- railway:signal:speed_limit=FR:P
- railway:signal:speed_limit:form=light
- railway:signal:speed_limit:speed=*
- ref:railway:signal:speed_limit=*: signal identifier (optional)
Milestone Speed Limit Markers (Km sign)
The Km sign (pancarte) is used in conjunction with TIVs to indicate transition points of the speed limit within a section of line when these do not coincide with notable landmarks.
- railway:signal:speed_limit=FR:Km
- railway:signal:speed_limit:form=sign
- railway:position:exact=*
- ref:railway:signal:speed_limit=*: signal identifier (optional)
Routes
Routes are signaled with either a Route Indicator or a Distant Route Indicator, or both. They are called Indicateur de Direction (ID) and Tableau Indicateur de Direction à Distance (TIDD) respectively. The TIDD indicates the position of the next point, either left or right unless the next signal displays a closed Carré (FR:C) in which case, the TIDD is turned off.
Route Indicators
- railway:signal:route=FR:ID
- railway:signal:route_count=* (number of possible routes, between 2 and 5; one light per route)
- railway:signal:route:form=light
- ref:railway:signal:route=*: signal identifier (optional)
Distant Route Indicators
- railway:signal:route_distant=FR:TIDD
- railway:signal:route_distant:form=light
- ref:railway:signal:route_distant=*: signal identifier (optional)
Cabin Signalling
Cabin Signalling Line Announcement
The train is directed towards a cabin signalling line. One or more signs (tableaux) of this type precede the entry.
- railway:signal:train_protection=CAB
- railway:signal:train_protection:form=sign
- railway:signal:train_protection:type=announcement
- ref:railway:signal:train_protection=*: signal identifier (optional)
Cabin Signalling Line Entry
The train enters a cabin signalling line. This sign is at the position of the last signal or immediately downstream of that signal.
- railway:signal:train_protection=CAB
- railway:signal:train_protection:form=sign
- railway:signal:train_protection:type=entry
- ref:railway:signal:train_protection=*: signal identifier (optional)
Cabin Signalling Line Exit
The train is returning to a traditional lateral signalling line.
- railway:signal:train_protection=CAB
- railway:signal:train_protection:form=sign
- railway:signal:train_protection:type=exit
- ref:railway:signal:train_protection=*: signal identifier (optional)
Other Signs
Upward-Pointing Chevrons
Upward-pointing chevrons indicate either an exit from a junction of converging tracks or, in some stations, the point beyond which trains must not proceed when a stop is required.
