Sure. Where are you leaving from? For an arrival of what time? How about TR3864, which leaves at 22:40? They arrive at 23:08.
I am looking for a train on Friday that leaves after 21:45. I'll be leaving from Cambridge and I want to go to Stansted Airport. I need to leave after 21:45. Yes how long is the journey please?
