Names of service

Like other Transilien lines the name of service consists of four letters, but is not always displayed on trains, but it can be seen on passenger information display systems.

Taking GEPU (which is for a train that runs express between Paris-Montparnasse and Sèvres-Rive-Gauche then stops all stations to Plaisir-Grignon) as an example, the table describes how names of services are structured.^[4]

Illustration	Explanation
GEPU	The first letter is the destination of the train, which is typically the first letter of the station's name. If a name of service begins with the letter P, this indicates a train to Paris Montparnasse. In this example, the first letter is a G, so the train terminates at Plaisir-Grignon.
GEPU	The second letter indicates whether the train will call at all stations, or not. An O in this position indicates an all stops train, with an E indicating an express between Paris-Montparnasse and Sèvres-Rive-Gauche, an A indicating an express between Paris-Montparnasse and Versailles-Chantiers, and an I indicating an express between Paris-Montparnasse and Viroflay-Rive-Gauche. Continuing with the example, the second letter of the four is an E, therefore the train runs express between Paris-Montparnasse and Sèvres-Rive-Gauche.
GEPU	The third letter is the train's origin. In this example, letter P is present in this position, so the train originates at Paris-Montparnasse.
GEPU	The fourth letter has four options: A, I, O and U. The fourth letter might have different meanings, but it creates a pronounceable code. In this example, the fourth letter is a U.

There is also codes given to Chartres TER services, which are PACE towards Paris-Montparnasse, and CAPO towards Chartres.
