Why isn’t there any information on the Cergy and Poissy segments?

These segments are operated by SNCF and not by RATP.

In December 2016, we began integrating information on trains leaving from an RATP station in the direction of an SNCF station. The arrival times of these trains are now available for your station.

The overall estimated travel time still needs to be fine-tuned, and we will continue to work actively with SNCF to provide you with precise, reliable information all the way down the line.
