The Lyon–Geneva railway is an important route in the national rail network. It connects not only Geneva but also feeds the Maurienne railway and the Geneva to Valence via Grenoble line. It carries a variety of traffic: TGV Paris-Geneva, Geneva - South of France, TER Rhône-Alpes, Rhône Express Regional and goods trains. The line is numbered 890 000 of the RFF national network.
Route
From Lyon-Perrache the line runs round Lyon city centre to Lyon-Part-Dieu. After running through the northeast suburbs of Lyon, the line runs in more or less straight sections across the plain to Ambérieu where it joins the line to Bourg-en Bresse and Macon,. The rest of the line winds through the foothills of the Alpes and Jura. At Culoz is the junction with the Maurienne line to Turin via Modane. From Culoz the line runs close to the Rhône to Bellegarde-sur-Valerine where it meets the Ligne du Haut-Bugey. After Bellegarde trains plunge into the 4 km Cret d'Eau tunnel, emerging at the Longeray junction, where the line to Evian branches off via the spectacular Longeray viaduct clearly visible from the line. Thereafter, the line descends close to the Rhône, crossing the Swiss frontier between Challex and la Plaine. Between la Plaine and Geneva stations are much closer together, due to commuter traffic for Geneva. Entering the Geneva conurbation through the Meyrin-Vernier industrial estate, with many goods sidings, the railway crosses the Swiss A1 motorway over a high bridge, then reduces to a single track beside the double track Cornavin-Airport line. Inside a tunnel, a triangular junction connects to the la Praille goods yard and future CEVA connection to Annemasse and Evian. Still in the tunnel, the line crosses the Cornavin-Airport line by a diveunder. The line emerges in the St. Jean quarter of Geneva to terminate at platforms 5, 7 and 8 of Cornavin station.
History
Creation
23 June 1856: Opening of the section from Lyon Saint-Clair to Ambérieu-en-Bugey.
20 September 1956: completion of the electrification with the section Bellegarde to Geneva. The inaugural train was hauled by CC 7121.
Evolution
In subsequent years the line has undergone various modifications, the most important of which are:
1980, opening of the cord line at Culoz allowing Genève - Grenoble - Valence traffic to pass through directly at 60 km/h avoiding the reversing movement in Culoz station.
27 September 1981 first commercial Paris - Geneva TGV service via Bellegarde, Culoz, Ambérieu et Bourg-en-Bresse.
12 June 1983 last day of operation of Lyon-Brotteaux station.
May 1987: Opening of the branch to Geneva airport. Most of the traffic West from Cornavin became long distance Swiss trains terminating at the airport in place of the relatively sparse traffic to the SNCF network. Accordingly, the main lines were reelectrified to the Swiss standard of 15 kV 16.7 Hz while a third line dedicated to SNCF traffic used a new single track line running parallel through to Cornavin.
12 December 2010: reopening of the Ligne du Haut-Bugey for TGV traffic to Paris, diverting TGVs from the Bellegarde to Ambérieu section.
Geneva-Bellegarde Section
All the different types of traffic mentioned in the introduction run on this section. Direct passenger services from Bellegarde to Geneva are provided by French TGV or TER trains, while stopping services are provided by the Swiss Rhône Express Régional service. Because it was electrified and signalled to a French system but operated in part by the Swiss Railways there were several unusual hybrids on the line, illustrated in the photos, including
French style signals built by the Swiss signal maker Integra
Upgrade Project Geneva Bellegarde 2014 25 kV
Suburban traffic on the Geneva- Bellegarde section is increasing steadily and the single track section is expected to become a serious bottleneck. The southern branch of the Geneva RER, the CEVA will be electrified to 25 kV 50 Hz, so the 1.5 kV DC electrification of the Geneva to Bellegarde section is a third voltage for regional trains. To alleviate these two problems, two engineering projects have been carried out, the first being to modify the double and single lines between Cornavin and the junction to the airport for bidirectional operation on all three tracks with either 25 or 15 kV, and the second to reelectrify the Bellegarde to Geneva section to 25 kV AC. The works were completed in August 2014, and the Bellegarde to Geneva section is entirely under 25 kV. Between la Plaine and Geneva, the signals are all Swiss, controlled from Geneva and allowing bidirectional operation. The Bem 550 and 'Flirt' 524 EMUs have been replaced by 'Flirt' 522s and 'Colibri' 562s
Upgrade Project 2018 bigger platforms
All platforms will be lengthened to 160m to allow for longer trains. The project should be finished by end 2019, with an estimated cost of 56mio CHF, financed by the Canton of Geneva
