Wivelsfield station isn't even in Wivelsfield. It's a crime.
And there's no such place as Upper Warlingham which is why the station is in Whyteleafe which, if there was any logical sense in the matter, would have at least stretched to being called Lower Warlingham as it really is a lot lower. Apparently it was prefixed Upper because Whyteleafe South station was called Warlingham despite it not being in Warlingham and really being Caterham North. Caterham Junction, on the other hand, had to be renamed Purley primarily because it's in Purley (which now has more settled vampires than Transylvania, but that's another story). Whyteleafe South is, of course, near to the Anne Summer's Dildo Proving Ground and it's rumoured that, late at night, you can hear the tremulous vibration of dysfunctional sex toys. It's like Area 51 but with more négligée.
