I have been planning a layout for my loft with no 2 and no 3 radius curves and was intending to put some curved points in the layout aswell. Although the layout will be predominantly British I do also want some American and German engines. The Bachmann 4-8-2 Heavy Mountain is not recommended to run on less than 22in radius curves so I will have to reconsider my plan. Peco and Hornby only do no 2 to no 3 curved turnouts ( Peco also do a very large radius curved turnout) so I am a bit stuck. I see from the Walthers catalogue that the American manufacturers seem to do a larger range of curved turnouts. I could presumably order these from the likes of Model Motors but can I assume that they would be interchangeable with Peco or Hornby track. Alternatively are there any other UK manufactures that I don't know of? Would the only problem of running engines on tighter than recommended curves be derailment or are there any other considerations?
Thanks
