The gap was closed in June of the same year, when the Geneva–Versoix Railway (Chemin de fer Genève–Versoix, GV) joined the two cities.

Regional services between Coppet and Allaman ended and six stations were closed: Founex, Céligny, Crans, Prangins, Gilly-Bursinel, and Perroy.

[3] As part of the improvement of the line, it is planned to install a fourth track between the stations of Renens and Lausanne.

This will allow increasing services on the Vaud regional express network to run every quarter of an hour.

This grade separation would be used by the Cully-Cossonay lines of the Vaud regional express network as well as IC services arriving from Bern and running towards Geneva.

This project also involves the modernising of the Lausanne operations centre and the building and rebuilding of associated technical premises.

The stations between Geneva and Coppet have to be redeveloped with an extension of the platforms to 220 metres and modernised and signalling has to be adapted.

[9] The line is of great importance in passenger transport, connecting Geneva to the rest of the Swiss Federal Railways network.

Gallen, as well as InterRegio trains from Geneva Airport to Lucerne and Brig, run the full distance.

In addition, the Geneva Airport–Morges section is used by ICN tilting trains running via the Jura Foot Railway to Basel SBB and St. Gallen.

Regional services have been abandoned between Allaman and Coppet and all stations except Rolle, Gland and Nyon have been closed.
