I have to say so far I'm impressed with TSGs work on the G6. Nice little Shunter and a lot of stuff to do with It would also be nice to bring in at least the BR 204 as showed on the Preview Stream! Consider bring in the 363 aswell as it would fit perfectly.
There is an attempted explanation for this over here: https://forums.dovetailgames.com/th...-2-tsg-vossloh-g6-services-for-dra-363.49118/ Yes, it has to do with shunting moves.
