All services that have loco NOT running should have a Cold Start flag as this is a good reminder that if you have not driven that loco for awhile, a training refresher might be a good idea. There should be plenty of CS in timetables from Depot to end station early runs. Ideally there would be no tutorial hop: smart tutorials would engage that very service as the context.
Agree. Would be a good reminder for beginners also for the Expert 101 Expert Mode that you need to put the one switch to "ZWS" which i personally forgot alot in the beginning
