In the Fast Lane scenario, the instructions at East Corydon are the wrong way around. Instead of telling you to load passengers first, it tells you to apply power go get moving then load passengers making the scenario impossible to complete.
I have encountered the same problem myself. Have tried the scenario 4 times and always ends up the same.
Says 'Fast Lane' on my scenario. But yes there is an error also the way the introduction is written I think it should stop at more stops than just East Croydon and Clapham JN? Anyway once you arrive at East Croydon there is no load wheel so unable to complete.
This issue seems to be platform specific as there is no such problem on PC. There is no apply power instruction at East Croydon and the times match up correctly:
Having the same issue. Time is out by eight hours and when you stop at Croydon it immediately tells you to apply power. Seems to PS4 (5?) specific as I watched a YouTube video of it on the PC and it works.
This scenario seems fine on PS5 as I completed it a few days ago (completed all scenarios) so it does sound like a specific platform issue.
PS4 then as I have a start at 18:30 Then East Croydon at 10:41 with the Apply Power in the log also no stops until Clapham Junction, Yet I believe it's an all stations to Clapham Junction scenario not a fast service?
