Un ottimo dlc potrebbe essere l'ETR 610 "il nuovo pendolino" della ditta FFS. questo treno viene utilizzato come eurocity sulla tratta Ginevra-Milano. i hope that will add trains like this il giro in taxi:
How about Dreilanderbahn Bludenz-St Margethen-Lindau where they run the St Margethen-Lindau leg towards Munich Central Station since 13 December 2020 from this Swiss German Newspaper
yes, it could be a great idea. this line with the ETR610 would be great to try beacuse This train is approved for travel in Switzerland, Germany, Italy. Ferrovie dello Stato Italiane will soon implement a new passenger service that will travel on the Milan - Munich - Berlin high-speed line using the Frecciarossa 1000/ETR1000. it is an Italian high-speed train capable of reaching 400km/h. I hope they'll add these two trains because they are very beautiful and fast!
