We love a good Reddit AMA (that's Ask Me Anything for the non-Redditors among you) -- a tradition where people with interesting jobs or experiences post a thread and people can, as you might have guessed, ask them anything.
A London Underground driver posted one yesterday, and to save you mining the very long thread for gold yourself, we've compiled the most interesting tidbits here.
1. There's been a successful trial of 4G on the tube
Just as we're about to get 5G, the tube catches up to 4G! Seriously though this is great news, it's really annoying only being able to get WiFi signal in the platforms.
2. There are secret driver toilets at some stations
And you might have had to wait on a stopped train while a driver went for an urgent poo upstairs.
Fair enough really.
3. There's a secret list of people who are allowed to ride up front with the driver
But it probably doesn't include you. Sorry.
4. Tube drivers do not appreciate you sticking your hand out
You're not the first person to think of it. You're probably not even the first person to think of it today.
5. There's a police-branded fire engine for lifting trains off people
6. There are tricks to not falling asleep while driving the tube
You're not allowed any kind of electronic device up front with you, so you can't even listen to music.
7. The "three suicides and you're out" thing isn't true
The movie is 'Three And Out' starring Mackenzie Crook, aka Gareth from The Office.
8. You do get paid leave though
More than fair enough.
9. That ominous 'Inspector Sands' announcement usually means someone's messed up their breakfast
It could be something much scarier, of course, but it's usually not.
10. It's really, really hard to get into
Yes, it pays well, and yes, you get free travel, but it's a really hard job that's not for most people.
And those wages aren't as inflated as you might imagine:
Yep, even the ones on over £100k:
The AMA is still going at the time of writing, and there's loads of Underground gold to be found in the comments. Read it here.
