TER Alsace was the regional rail network serving the région of Alsace, eastern France.

Some old lines will be opened again, and new trains have been ordered (Alstom Régiolis) and will be delivered in 2013–2014.

At the same time, the region is currently putting in place Alséo, a magnetic card allowing access not only to the urban transport networks of Strasbourg, Colmar and Mulhouse, but also the TER network.

The Thur valley tram-train, between Mulhouse and Thann, began operation in December 2010 with Siemens Avanto rolling stock.

[1] A tram-train between Strasbourg, Molsheim and Barr has also been proposed but won't be realized before 2018[2]
