I've just started training as an "Electric Train Driver".
It's 12 - 18 months training, and a lot more involved than you'd think. So many people think it's "go-brake-go" - but there's so much more you have to know.
So far, it's challenging and fun

. You've always got to be concentrating and thinking ahead. There's a lot of technical and mechanical skills you have to have too that most people don't think about (who do you think is in charge when things cock up, eh?

).
My employer is owned by the state government - so they're stable, pay well, and very trans friendly.
I changed my name and title before I started (but after I applied) and they offered (yes - offered!) to change my gender marker with HR. It's a totally different culture from the private sector. They don't care if you're a minority, they care only that you can do the job.
I came from the IT industry. Computers are awesome, but I don't think I'm cut out to wear a suit and brown-nose to clients

.
