Just wondering what call there is for 6mm buildings for railways? I manufacture 6mm resin buildings and have produced a range of typically British railway buildings - era around 1940s to present day. I would like to expand the range, but only if it's going to be worthwhile. Alternately, anyone got any suggestions for a suitable scale to produce some in?
Railway buildings for 6mm are only good for Z gauge which is limited to one railroad model manufacturer (Märklin 1/220th scale) it you aim to railway layouts/model railroaders for ascending numbers of sales. That said, Maärklin does not produce any British railway model...
Wargaming wise you could think about casting tracks, trains or train sections (of three wagons or so).
20mm gamers will be thankful for buildings in 1/72 (better 1/76 for the 00 railroad modelers too) and 28mm gamers for any in 1/50-1/60, I guess.
