Hi there, I'm going to be doing a layout at some stage in HOn3.5. This will be a Tasmanian themed layout. Most Tassie layouts at the moment are some sort of S scale variant, but one of our local makers is making a loco in HOn3.5, this then makes all my other scenic elements work, like cars and buildings. The loco is not yet available so haven't made any sort of start yet. In the 1:1 world Tasmania uses 3'6" gauge. Cheers Tony
