Crossover timbering advice please

Penrhos1920 · 13 November 2023

I've drawn a trailing crossover and I'm trying to sort out the sleep positions. I wouldn't have noticed the problem had I not turned on the experimental 3D railchairs which show that my attempt means that I couldn't fit in a railchair for the straight route next to the opposite side checkrail chair.

The problem is the X5-B and X7-D sleepers. I've shoved the sleepers so that X2 to X8 are shared by both turnouts. At this point without 3D railchairs I would have been happy and somehow trimmed and squeezed railchairs in place. But the 3d railchairs show that X5 chair does not allow a chair on the X7 sleeper of the other turnout. I've tried Equalized sleepers and end up with a similar issue. I'm modelling 1904 Rhymney bullhead track just in case someone knows what they used to do!

Thanks,
Penrhos

Penrhos,

You need to extend those timbers right across both running rails, the section covering both Vees will be block timbering and may also be centre line incremental, I'm on my tablet, so I can't check it out at the moment.
