I have the Wupper Express 12. I converted the later version to use standard MSTS skies because I could not get the weather thing to work correctly.

About defunct sites, A real pita sadly. I wanted the activities for the Romanian Rail route that used to be on Black Rail's website, but have never been able to turn up the acts or stock packs. The route is beautiful, but life less without acts and stock common to the specific route.

I've also never been able to find all the stock needed by the Hungarian route. They mostly have moved on to ORTS like the Romanian guys.
