Arnos Grove
"Could it be because it's a hole"
A bit harsh but that could be the reason for a local nickname "Anus Grove"!
The station is about 2 miles from my humble abode which is nearer to my eponymous station on the Northern Line. AG not only has wacking great sidings where tubes go to sleep at night, but it also has a strange central platform which can operate in both Northbound and Southbound modes and doors that can open on either/both sides.
It confuses the hell out of me and I'm just a passenger so what it does to train staff is anyone's guess.
