After living in Germany... British railways seem like an enterprise level SLA.
Tickets with a short expiration time (2 hours... why?), hour(s) long delays, sudden last minute platform changes (you need to use the underground passage full of people), trains just disappearing off the screen with no notice after being delayed several times (I mean, come on!), incredibly rude controllers who just seem like they really want to throw you in prison for not having a ticket (oh yeah, that's a thing, take that Brits!), shoddy rail and frequent stops in the middle of nowhere (or 100 meters from your station), trains that make the Pacers seem like Cadillacs (OK that was one time, not sure where they pulled that pos from)...
I kinda see why Germans hate Deutsche Bahn :D
