Here are a couple that I set the train back to just short of the next 'red signal' behind then ran at good speed through Acton and Reading stations. By creating a new player profile and naming it for each one of these then "save"
That Reading one is about the only one because the platform it starts at does no have a signal guarding it so you can set back about half mile to one. Will study more scenarios to see what can be done.. pity we cant change points??
