Add a route from Praha hl.n. to Ceske Budejovice, alongside with one local track - Benesov U Prahy - Sedlcany. Additionally, add the needed locomotives (380, 36X, 810, …). I can provide pictures of certain stations if needed.
You'll need to give us a lot more detail - as this is your first post here (welcome!), I commend looking at the pinned thread Matt's Advice On Tsw Suggestions on how to set out a good suggestion.
as much as I like 380, if I recall it being called Emil Zatopek, it didnt have much success apart from some regional and a couple EC lines, and is currently being phased out in favor of Vectrons... design-wise a nice machine, I imagine Skoda had high hopes of competing with Taurus at least, but it wasnt meant to be, I guess (plus it had numerous reliability issues... I can see why Skoda leans more into EMU/DMU units than locos)
Personally I would like to see another single track rural diesel route, but this time with a 749 plus coaches and an 810 (or 854). I’m guessing we don’t know how successful the Liberec route has been or whether the team is already engaged on another project.
