27 years old. This is almost the “age” in Isère of the Lyon-Turin rail link project whose Prime Minister Gabriel Attal came this Tuesday, May 14 to Maurienne (Savoie) welcome the work on the transalpine base tunnel. It is an essential element of a connection which has changed both in nature and route in our department since its beginnings.
In 1997-1998, the inhabitants of Saint-Savin, north of Bourgoin-Jallieu, were among the first in Isère to protest against a “Lyon-Turin TGV” project, which ran alongside their village crossing the hills. Today there remains a project for a new line for a “fast” transalpine link – but without the term “TGV” – for use “mixed“, passengers and freight, from Saint-Exupéry airport to Chambéry and a freight-only section – for the moment – from the Savoyard front to Turin.
Update on the route in Isère
According to the maps provided during the 2012 public inquiry on the French part (see below), this new connection between Lyon and Turin will cross Nord-Isère for around fifty kilometers between Satolas-et-Bonce and Romagnieu, in alternately following the already existing railway line and the A43 and passing for example north of Isle d’Abeau and Bourgoin-Jallieu and south of La-Tour-du-Pin. Covered trenches and three tunnels will punctuate this route.
The route then reappears more briefly in the department on the border between Chapareillan (38) and Les Marches (73), at the exit of the “Chartreuse tunnel”, then under La Chapelle-du-Bard for a small part of the “Tunnel de Chartreuse”. Belledonne tunnel. It then plunges towards the Maurienne.

New rails in Nord-Isère in 2028?
The construction of the northern Lyon-Turin section will require “around two billion euros out of the nine billion total cost of the project” according to Stéphane Guggino, general delegate of the pro-Lyon-Turin Transalpine association. A project which is not for immediately, unlike that of the base tunnel. The SNCF will first carry out from 2025 pre-project studies with the municipalities concerned, in particular to try to minimize disruption on the route during the work. If nothing subsequently slows down or hinders the Lyon-Turin route, the first rails will appear. in 2028 in the north of the department The opening of the line is announced for 2032. In 1997, it was planned for 2020.
