Great that a V100 is finally coming. 212s were a class of 381 locos and worked all over the country, mainly on branch lines. I assume these will be going onto Niddertalbahn as they worked it during the time period the route is set.
Absolutely stoked for this. One of my favourite classes of locos and still working to this day in limited numbers. Niddertalbahn would indeed be a good fit, at least with some artistic license. I'm not entirely sure how common they were on that route in the 90s, but they certainly seem to have been there in numbers in the 80s. Source Source Source
