This is the first scenraio Down the Line of Great Western Express DLC. The train at Platform 10 was driven, which is the stopping service all the way from London Paddington to Reading. In Mission Summary somehow all the locations have crosses beside them despite me keeping up with the schedule (although sometimes 1 minute behind). Is this a bug or am I doing something wrong here? Thanks.
Make sure you are stopping at the correct positions at each stations. If you stop too early or late, then it’ll most likely give you a Red Cross for it.
The GWE scenarios are unfortunately bugged in this respect. There’s absolutely no rhyme or reason as to whether you get a cross or a tick...believe me, I’ve tried. Don’t sweat it, it makes no difference as to whether or not you complete the scenario. FWIW the services work fine though.
On the other hand, in some cases just stopping anywhere within the green part of the guide path (or whatever it's called) is sufficient. Perhaps this depends on the route?
