Hi I some of the picture that I saw in this forum, there is a blueish train that is hanging over some river, but I can not find this train either on steam or the store Can anyone tell me where I can find it
Yep, it's the Wuppertal Schwebebahn (Suspension Railway) on RRO, but it's just background scenery, as Stujoy said...
If you are really interested, there does exist a Wuppertal Schwebebahn simulator out there (of questionable quality, I haven't played it on PC in a long time). It's not TSW, but it could still be fun for you.
