I have spent literally hours trying to run this scenario, and each time I run it, it places me on the wrong track, so it is impossible to complete. What is suprising is I just bought the DLC last week, and apparently it has been out for quite awhile, and it appears that this bug was never fixed.
Not my day today. Decided to run a scenario on Birmingham to Crew,, "Contingency measures". Door jammed at every stop. Then the brakes on the 350 wouldn't release no matter what I tried. It appears to me that many of these Scenarios are probably best avoided, going to stick to timetables only I guess.
