Options that could be combined with this project were upgrading the Pont-de-Veyle - Polliat section to 200 km/h, and electrification of the Sathonay-Bourg line, with construction of two new stations, Bourg-north and Nurieux. With these additions, the Paris - Geneva journey time would fall to 2h15 and Geneva Lyon to 1h04, Paris-Lausanne in 2h50 and Paris to Evian reduced by 90 minutes. However, this option was considered to be far too expensive at 2.3 billion euros, mostly due to the extensive engineering works needed, and the project went no further. The Swiss authorities continued to push the SNCF for an alternative more affordable proposal.
