Transilien Paris-Saint-Lazare is one of the sectors in the Paris Transilien suburban rail network. The trains on this sector depart from Gare Saint-Lazare in central Paris and serve the north and north-west of Île-de-France region with Transilien lines "J" and "L". Transilien services from Paris to Saint-Lazare are part of the SNCF Saint-Lazare rail network.

The two lines are the busiest lines in the Transilien system, excluding lines signed as part of the RER.

Line J

The trains on Line J travel between Gare Saint-Lazare in Paris and the north-west of Île-de-France region, with termini in Ermont–Eaubonne, Gisors and Vernon. The line has a total of 260,000 passengers per weekday.^[1]

Services

Line J utilises four-letter codes, called a mission code or the name of service. The four-letter code begins with a letter that designates the terminus of the station.^[2]

The first letter designates the train's destination.

A: Argenteuil
C: Conflans Sainte-Honorine
E: Ermont-Eaubonne
G: Gisors
H: Houilles Carrières-sur-Seine
J: Vernon
K: Cormeilles-en-Parisis
L: Les Mureaux
M: Mantes-la-Jolie
P: Paris Saint-Lazare
T: Pontoise
V: Vernon
Y: Boissy-l'Aillerie

The second, third and fourth letters indicate the stations served by the train. Formerly, the second letter was used to designate the train type (I for express trains, A for semi-express trains, O for local trains), but this is no longer the case (but most all stops trains of Line J keep the O as the second letter). The third letter was also used to designate the route taken to the destination (for example C as a third letter indicates "via Conflans Sainte-Honorine"), but this is now abolished along with the second letter. Typically, mission codes or the name of services of line J have the following composition of destination, vowel, consonant, vowel (CARA, GENE, MOLE, PALE, TOCA, etc.) but only four codes follow the pattern of destination, vowel, consonant, consonant (PACK, PANS, TANS and VERN).
