This has been talked about for years and although to some it looks attractive, all I have to say is why!
if I wanted two rail I would switch to two rail. Trying to make something that it is not is a waste of time and resource. Yes I love my scale engines and they look great on my Ross track. Why would I waste my time on a product that looks no better then what I have.
Sorry but the time has past for stud rail, it was not feasible years ago and it is not today.
