This section describes the tagging scheme specific to French railway signalling, based on the international railway signal tagging model.

JOSM Presets

Dedicated JOSM presets are available for download directly from the application to simplify the mapping of French railway signalling according to these specifications. Please see French railway signalling JOSM Presets for more information.

Tagging

All railway signals must include the following tags:

  • railway:signal:main:ref=123456 where main is an example of one of the signal categories and 123456 is an example of an idreseau identifier provided by SNCF Réseau. One identifier is used per category and per physical signal, board, or sign at the node.

Optional tags:

  • ref=*: identifier shown on the marker plate (plaque de repérage) when present.


Stop signals

Carré

An absolute stop signal for normal train operations, typically found on main lines or at stations. The signal displays two steady red lights, arranged either vertically or horizontally. It is equipped with a clearing light (French: œilleton), which is illuminated in all states except when the signal is closed (i.e. displaying the FR:C state). The signal also features an identification plate (French: Plaque d'Identification) bearing the inscription Nf in white letters on a black background.

The signal may also be equipped with a marker plate (French: Plaque de Repérage) and/or a block system identification plate (French: plaque de cantonnement) indicating the block system beyond the signal. The inscriptions on these plates are written in black letters on a white background.

Optional tags:

Signal de milieu de quai (2TMV)
  • Illuminated white cross aspect on an intermediate signal
    Illuminated white cross aspect on an intermediate signal

Also known as an intermediate signal, this is a horizontal dwarf Carré signal used on platforms to manage two trains on the same track (French: 2 Trains sur une Même Voie). It features a standard dwarf layout supplemented by a central light capable of displaying an illuminated white cross. This system offers high operational flexibility, allowing two railcars to enter the platform sequentially (either from the same or opposite directions) to either depart independently or couple together.

Depending on the operational scenario, the signal presents the following aspects:

  • Carré: Closed to stop an incoming train at the middle of the platform. This aspect is announced by the upstream signal presenting a Caution (Avertissement) aspect combined with a flashing illuminated horizontal yellow band.
  • Illuminated White Cross: Cancels the signal when a multiple-unit train enters and occupies the entire platform, or when an incoming single-unit is routed to stop at the end of the second half of the platform. In these cases, the upstream Caution signal is presented without the flashing illuminated yellow band.
  • Caution: Displayed when the station's exit signal is open (e.g., displaying a Rappel 30), ensuring the train does not exceed 30 km/h between the intermediate and exit signals.
  • Flashing Red: Opens after an initial stop at the Carré to authorize a low-speed (15 km/h max) entry and safe coupling onto a railcar already stationary at the second half of the platform.

Cab signalling

To allow trains to run safely at speeds above 220 km/h, traditional lineside signals are replaced by in-cab signalling systems. These systems transmit movement authorities and speed instructions directly to the driver's cab.

In France, the two main cab signalling systems are Transmission Voie-Machine (TVM) and the European Train Control System (ETCS).

CAB boards

The train is directed towards a cab signalling line. One or more boards of this type precede the entry.

  • Cab signalling line advance board

  • Transition from 1500 V DC to 25 kV AC: Required when switching from direct current (DC) to alternating current (AC) power supply.
  • Between Two 25 kV Substations: Necessary due to phase shift, potentially creating voltage differences of up to 70 kV in case of opposite phases.
  • Phase Change: Used to redistribute the electrical load within the network.
  • Cross-border Areas: Needed when crossing borders where different electrical systems may be in operation.
  • Crossing Certain Structures: Specific structures may require the pantograph to be lowered for safety or operational reasons.

Tableau Lumineux de Correspondance

A Tableau Lumineux de Correspondance (TLC) for converging tracks is a signal installed to the left of the track it addresses and is normally off. At any given time, it can display one of the following:

- A white letter T, either fixed if the group signal is open or flashing, if the group signal is closed.

- The Signal Lumineux de Départ if applicable.

- A red and white checkerboard, which has the same meaning as the Jalon d'Arrêt and is used instead of the chevron.

Tableau Indicateur de Provenance

At the exit of some service track yards, a Tableau Indicateur de Provenance (TIP), a track indicator, complements the chevron. It can display any of the numbers designating each of the tracks. When the TIP displays a number, the driver on the corresponding track is allowed to cross the chevron. When the group signal is closed, the driver can advance to an agreed point, usually in preparation for a reversing movement.

  • Tableau Indicateur de Provenance

Service tracks and shunting

Signal Lumineux de Manœuvre

A Signal Lumineux de Manœuvre (SLM) is installed in some installations to facilitate shunting operations on main tracks (for example, pushing a train into a siding) or on service tracks. It consists of three white lights, which are normally unlit.

The SLM can display the following aspects:

  • Pull (Tirez): two white lights alternating on a vertical line.
  • Push back (Refoulez): two white lights alternating on a horizontal line.
  • Stop (Arrêtez): all lights extinguished.
  • Observe hand shunting signals (Observez les signaux à main de manœuvre): all three white lights lit simultaneously and steadily.

Several similar signals may be installed along the same track to mark the full extent of the shunting area. In such cases, they are numbered with Roman numerals in descending order (e.g. III, II, I), with SLM I being the closest to the switch and identifying the terminal signal of the shunting area.

Note: SLM are no longer installed on new installations due to the widespread availability of shunting radio, either permanently installed on shunting vehicles or provided as portable equipment on line locomotives.

Level crossings

Most French level crossings are equipped with Automatic Light Signalling (SAL) (French: Signalisation Automatique Lumineuse et sonore), which warns road users using flashing red lights, audible alarms and, where fitted, barriers.

Depending on the installation, the warning sequence may be initiated automatically, manually by the train crew, or by a radio command transmitted by the train driver.

Level crossing announcement

This announcement sign informs the driver that they are approaching an unguarded level crossing where specific operating instructions apply.

  • Level crossing advance sign
    Level crossing advance sign
  • Level crossing advance sign with Radio sign
    Level crossing advance sign with Radio sign

When fitted with an additional Radio sign, it indicates that the approaching level crossing is operated by radio control. In this case, the following tag must also be specified:

Radio-controlled level crossing

This board, installed approximately 350 m before the level crossing, marks the location where the train driver must transmit a radio command that initiates the warning sequence.

  • Radio command sign
    Radio command sign

Level crossing ahead

This sign is placed immediately before the level crossing and identifies the crossing by its number. It also indicates how the crossing is operated.

  • Automatic mode (no white band): the warning sequence is initiated automatically by the approaching train.
  • Manual mode (white band): the warning sequence must be initiated by the train crew according to operating instructions.
  • Automatic level crossing sign
    Automatic level crossing sign
  • Manually operated level crossing sign
    Manually operated level crossing sign

If the level crossing is manually operated, the following tag must be specified:

Signal de Franchissement Conditionnel

Radio-controlled level crossings are additionally equipped with a Signal de Franchissement Conditionnel (SFC). This signal consists of one or two green lights, arranged vertically or horizontally, and installed close to or above the level crossing sign.

When illuminated, the SFC confirms that the level crossing has been activated successfully and is securely closed, authorizing the train to proceed without stopping at the PN sign. When unlit, it is equivalent to a stop indication.

Clearance signs

This sign marks the approach to a permanent reduced clearance.

  • Reduced clearance sign
    Reduced clearance sign

It may be grouped with a sign indicating the number of upcoming tunnels.

  • Tunnel sign

Optional tags:

When a J plate is present below the S sign, it indicates that the whistling obligation applies only during daytime (between 07:00 and 20:00).

Snowplow

- The snowplow lowering signal indicates the location where trains equipped with a snowplow must lower the snowplow.

  • Snowplow lowering signal
    Snowplow lowering signal

- The snowplow raising signal indicates the location where trains equipped with a snowplow must raise the snowplow to avoid striking obstructions.
