I wanted to suggest this two car, tilting, diesel multiple unit. The vehicle is primarily used as a regional express and InterRegio Express. The class is also known as "RegioSwinger". The maximum tilt is 8°. There are quite a few services the Class 612 is used on(I know this list is outdated, but it works for this purpose): https://en.wikipedia.org/wiki/DBAG_Class_612#Services I'd like to see the Class 612 in TSW, because it could technically be used on any German map due to the diesel motors and it would be a tilting train, which would be cool to see in-game.
