It is the biggest modernization in the history of SBB long-haul traffic: The 341 IC2000 double-decker coaches will be upgraded for a further 20 years in service. The modernization includes implementing contemporary and future customer requirements, complying with Swiss legal requirements concerning access for people with disabilities and the modernization of vehicle technology.

The IC2000 trains are the backbone of the long-haul intercity fleet and were purchased between 1997 and 2004. They operate on the Geneva - Bern - St. Gallen and Romanshorn - Brig routes, among others. The IC2000 fleet will continue to be of central importance after the modernization to meet the increasing demand for seats.
