Greetings all,
First, my apologies for posting in English, but sadly I don't know how to speak German.
I know making rail yards is passion that many of the train lovers do share, and I've been able to find many cool decoration assets for that purpose, but so far the only sand tower I've found is a very nice 'steam era' model, but it doesn't fit very well the visuals of a 'diesel era' rail yard.
So I'll leave some inspiration images (links) below, in case somebody wanna give it a try - I think it would be cool to have both one-rail and two-rail servicing versions, like in the images below.
