Tourist... information found :)
Thanks to Frac from Germany, I managed to identify the train. It`s an Intercity German Train that runs from Venice to Munich.
This train was headed by an electric OBB locomotive passing at 18:50 in Trento Station, heading to North for crossing the Alps over the Brenner Pass.
The photo was taken from the Sardagna hill placed on the ”Funivia Trento - Sardagna (600 metres altitudine)” route.
