Close

Each train is composed by several railcars; some of them have a cab and a wheelchair bay for disabled people (MCH), and some of them have neither (M).

″MCH″-railcars were numbered by LeNord as E.711, ″M″-ones as E.710. In total, 208 MCH and 252 M railcars were built. The traincars can be formed into trains consisting of 3 (MCH + M + MCH) to 6 cars (MCH + M + M + M + M + MCH).

The TSR were conceived by AnsaldoBreda and Firema as an evolution of the TAF-EMUs built in the 1990s. The first unit was delivered to the railway company LeNord (later merged into Trenord) on 1 August 2006.^[1]

The last train was delivered on 31 March 2012.^[2]
