... reduced to 30". I also reduced the flangeway end gap to only 1.3mm. The result is that a working check rail can just about be made to fit. The check rail length is severely under-scale but it manages to look the part: em6_slip_k.png But using the same settings in 00-SF produces a conflict. You might decide to live with this. It means filing the back of the check rails to fit, which looks a bit odd, but the check rails are still long enough to work: 00sf6_slip_k.png A possible change is to use a shorter switch.

But it eases the slip road radius to 65", and makes room for the check rail with only just the corner needing to be removed: 00sf6_slip_k_20sw.png An alternative solution is to change to movable K-crossings (switch-diamond ...
