Class2ldn, forgive me, but you'll probably be earning a lot more now in your current job (with potential to earn more given your age) than you will as a pilot, so do think very carefully before making the jump, particularly with no g'teed job at the end of it. There's quite a lot on here about the comparison between pilot and train driver jobs if you can find it - I have limited understanding of what's involved in being a driver, but one thing I'm pretty sure of is you don't have to pay for your training and job is a lot more 'protected' and secure than a pilot's - and you'll probably see a lot more of your family too. I'm sure there are some guys who'd gladly make the switch the other way given half the chance!
