BR 204 should also have tasks., services at the other Aschaffenburg on Maintalbahn. Even smarter would be offering a very short extension to both routes to Hanau ... let an aspiring third party go for this small project. If Rivet Games cannot see their chance to improve their BR204, why not do this project using BR363 ? It would be the same project but in reverse: BR 363 DBB is already on Maintalbahn !
I think the BR 204 is not given enough attention, a new paint job for free or via a Railtour Pack would be nice. but it would also be possible if the 204 were unlocked for the paint editor. A few more services would suit her well and I would also be happy if she would just stand around somewhere as an asset or be integrated more as an AI vehicle.
