Easiest Job I've ever had Ian and I'm looking forward 2014/2015 when I wont have to drive and as you say simply press go.
It can get a little nervy when you're in a tunnel between London Bridge and Bank on a Monday morning and the train wont move and you've got 1000+ people on the back but thankfully thats a rarity.
Speaking of drunks I've been on lates this week and I've had my fair share of drunks to wake up and get off before putting the train in the depot. I don't like Saturday and Sunday nights.
But your right I'd rather drive a Train than a Bus.
