At the end of May, Railcolor News brought you a preview of the X’Trapolis Cityduplex (aka ‘RER NG’), while on the move as a ‘dead’ train. Now, tests are advancing and the test unit is already moving on its own.
Railcolor News thanks Romain Vergneres for his image contribution.

The image below, which was taken on 26.06.2020, shows the first trainset Z 58001/002 at CF2 in Nançois-Tronville – shortly after its departure from Nançois to start on the 12-kilometer test track:
