Hello, I am a Train Driver!
The good - aside from occasional assessments, you are very much left to your own devices. Interaction with your line manager is relatively rare. Obviously when you go home, you're done, so work/life balance is good in that regard (although the shifts do impact on your lifestyle, when you can have a drink, how early you need to go to bed etc).
The bad - there are few women, although more are joining. But sexist attitudes prevail unfortunately.
It takes a great deal of focus. Train Driving doesn't demand your concentration in the same way steering a car does, once you've got the thing up to speed, as long as you're running on greens then it will just go and go with very little interaction from you. Missing a station is very easy indeed. It's also quite lonely in there, no music allowed... so you need to enjoy your own company.
The ugly - fatalities. I have had one and coming back from it was a struggle.
Ask me anything, I'd be happy to help. Get your application in quickly, my company often withdraws vacancies before the closing date due to the huge influx of applicants. Emphasise your responsible nature, that you can work independently but also follow rules and procedures, that you know how to prioritise tasks, mention safety as often as you can. Convince them you will be able to memorise the rule book and will be able to cope with the lengthy training period. Mention any experience you have dealing with emergency situations. And then get prepping for the psychometric tests, because they have a 95% failure rate.
