Excuse me but the scenario you posted is completely backwards, the railway circulation in Italy, to the left on the even tracks, to the right on the odd tracks, to make you understand Venezia Marghera tracks 1 and 3 towards Venezia S.L., 2 and 4 towards Venezia Mestre, same thing for the entry and exit tracks, Gazzera 1 and 3 exits Udine Trieste, 2 and 4 Entrance Venezia Mestre, Line 53 and 54 Odd tracks towards Mestre, even tracks towards Padua and other directions.
