... for controlling the route? Hi Ian, Such designs were found in tram tracks, but in that case the wheels are guided by the special flanged tram rail and housed switch points. It won't work for ordinary standard-gauge because the opposite rail needs a check rail for the straight-ahead route. Which it can't have because the moving switch rail is in the way. See the long check rail in my previous diagram: 2_182013_060000000.png In fact your design has a gap in that check rail just where it is needed: 2_010745_000000000.png I'm intending in due course to use your mixed-gauge design as the basis for a tutorial on using partial templates. But you have gone ahead and built it at a rather more furious pace than we are used to in these parts. cheers, Martin. posted: 1 Oct 2019 13:02 from: RedgateModels Could the open switch blade act as a check rail? That's how the NG main route is controlled on the right hand turnout.... Thanks for pointing out the gap, I had spotted ...
