2 things from me, learnt last year, six years after I got MSTS!
1. I didn't know that if you stuffed up the departure time in AE and was later than the time you wanted it (so the arrival was stupidly early), you can just uncheck the station in the location list and check it again, and it will reset the time to 00:00 for that station only. Before I either re-did whole timetable or went into Activity Changer to fix it!!
2. Again, something I learnt last year, there is a deadman's 'Alerter' in the sim. I was driving a 73 at Eastleigh and wondered why every time I moved there was a 'beepbeepbeepbeep' and the loco kept grinding to a stop. I checked everything until I went to the options and saw the Alerter box checked (somehow) and now I know what it is...
Is this in the manual or have I obviously skipped that bit?!
Cheers,
James.
