He is staying with friends in a small town in Devon, and planning to take a 6:07 train (First Great Western) to London Paddington, which arrives at 9:21. He would then need to get to the tube station, take the tube to LIverpool Station, and get on the Stansted Express. The Stansted Express apparently runs every 15 minutes.
The National Rail site indicates that he could arrive at Stansted by 11:14--- but this doesn't include the possibiltiy of late trains or getting lost or confused.
Do any of the experts here think this is a safe bet? Or should he take a train in the night before? He really can't afford to miss the flight. I personally am a little nervous about how tight this schedule is.
(I've cross posted on the Train Travel forum, as I'm not sure which would be better for this question. Thanks for any help!)Edited: 3:36 pm, April 18, 2013
