In 1982, FS retired the ETR 401 from service, due to high maintenance cost, and FIAT transformed it in a train-laboratory, to test the parts for the successor of the ETR 401, ETR 450. After 1988, the trainset went around Europe to demonstrate the greatness of the tilting revolutionary technology and between 1994 and 2001 it was utilised as a charter train. In 2001 the ETR 401 was put aside in Ancona and since 2013, to celebrate the 25th anniversary of the first official pendolino service, it has been partly restored.
