List of locomotive and multiple unit classes of SNCF. Classes in bold are in use, whilst those in italics have been withdrawn.
Numbering Scheme
Locomotives and Multiple Units
Vehicle numbers are three to six digits long. The first (not always present) digit indicates the sector in which that vehicle operates:
- 1: SNCF Voyages: high-speed services, including the TGV
- 2: Intercités: medium-distance services
- 4: SNCF Fret: freight operations
- 5: Transport Express Régional (TER): urban, local and regional services
- 6: SNCF Infra: maintains rail infrastructure, the assets of Réseau ferré de France (RFF)
- 7: Departmental use
- 8: Transilien: commuter services serving Île-de-France
The next (possibly first) two or three digits of a vehicle's number indicate its class, in loose bands corresponding to the traction and power output of the stock:
thumbnail|A [[SNCF Class BB 22200|Class 22200, 195th in series, operating under TER bears the number 522395.]]
- 0-9999: DC Electric
- 10000-19999: AC Electric
- 20000-29999: Dual Voltage
- 30000-39999: Triple Voltage
- 40000-49999: Quadruple Voltage
- 60000-79999: Diesel
The final digits uniquely identify the engine within its class, but in the case of a three digit class number, the engine number may begin adding to the class number (for example, a Class 22200 may have a number beginning 222, 223 or 224).
Multiple units are numbered the same as locomotives, but prefixed by X for DMUs or Z for EMUs. Diesel shunters are prefixed Y. A now discontinued practice was to prefix the class number by the wheel arrangement.
TGV numbering scheme
Each TGV trainset has its own number, found on the nose. Within the set, each vehicle is given its own number. The power cars are numbered by the standard locomotive numbering scheme, prefixed by TGV. The trailers are given a number which consists of the first two digits of the power car's number, followed by the number of the trailer in the set, and finishing with the number of the trainset, prefixed by TGVR or TGVZR, if powered.
