Alstom Coradia Polyvalent

The Régiolis is a category of multiple unit train built by Alstom coming from the Coradia family. The first train was presented on July 4, 2013, in Aquitaine, and the first commissioning took place on April 22, 2014, on the TER Aquitaine network, more than a year behind the initial schedule.

== History == left|thumb|Presentation of the first Regiolis trainset, in Strasbourg on December 5, 2011 In the 2000s, the delivery of several hundred new trains, X TER, A TER, AGC, or TER 2N NG provided significant modernizations of the regional electrical and diesel fleet. However, in the early 2010s, old types of rolling stock dating from the 1970s and 1980s continued to operate, it became necessary to continue the renewal and growth of the fleet during the period 2013–2022 due increasing TER network usage. This desire manifested itself with a call for tenders from SNCF, for the design of a new type of train, the "versatile carrier" ("porteur polyvalent" in French). Following the Grenelle Environnement and the successful usage of AGC dual-mode equipment, this equipment must not only have a diesel version, but electrical and dual-mode versions, to avoid any usage of the diesel engines where overhead catenary is available.
