Yeah same promble on northern trans pennie aswelll i think their are looking into signal promble for both routes on scenario designer so their are
So ran a class 166 from just outside of leeds to just before manchester and it worked. I never could get the hang of the equipment on that line so I didn't ever get a chance to play it. Such a beautiful line, I'm shocked at how amazingly nice it is!
Other weird observations, as long as you don't start in Manchester you can drive into it. Leeds however gave me a signal passed at danger warning right before the platform still.
