Stuck At Red On Gwr

So I just bought Tsw 2 and transferred my dlc. When I'm driving the down the line scenario on the GWR route I get stuck at red and can't leave the first station.

 

Is this the one that gives you the choice of three services? If you select the shortest one (like I did), you have to wait until the other services leave first which takes a while.

Try one of the other services instead and hopefully, you’ll get the green light quicker.

 

Iirc they shortest runs, hayes and slough were bugged, and only the run to reading was completable.
