I can't be the only person who would like some scenarios to begin away from a station (off the top of my head I don't think TSW has any which aren't freight). Varying the starting point in some scenarios would add a bit more realism to them. The train could be pre-set up as required and the player starts the scenario held at a red outside the station. e.g: Good afternoon driver, you're held at a red light outside of Reading, when cleared to proceed you'll be stopping at platform 3 where boarding will commence. Once boarding is completed, continue your journey to London Paddington. To counter some people who'll say it's unrealistic for a player to start at a red outside a station as the driver will always pick up a service at a station. That's what service mode is for, scenarios are there to give the player a bit more of a challenge and what's to say "the driver" didn't drive to this point? I see this in TS but never in TSW. I hope I've explained this as best as I can.
On GWE for example have the train held at Reading West- they frequently used to be- waiting for the Reading platform to clear?
