Just seen this thread.
I'm 33 and a train driver and I'm looking at making the change. I'd have to go modular though as I couldnt afford to give up my job.
Quite a scary prospect of spending all that money and having no job at the end.
I have about a year to be able to go back as a qualified driver after which time Id have to start again as a trainee.
Definitely something I'd have to think seriously about.
Going to do my ppl and see where I am after that.
