I've created a few custom scenarios on a few different routes using the off the rails mode. Most of my routes seem to work but one specific one gives me a permanent red signal at the start point. I created a route on NTP using the class 166 from Leeds to Manchester calling at Dewsbury and Huddersfield only (express route). The reverse route from Manchester to Leeds works fine every time but the route from Leeds to Manchester won't allow me to get past the start point at Leeds station. Anyone have any ideas how I can solve this issue?
