There’s something about London’s abandoned structures that fills people with a kind of macabre delight. Above ground the city moves so quickly, with property being so expensive, that decaying buildings are most often quickly torn down and replaced with a more modern façade. But underground, there is not the same necessity.
There are a handful of disused tube stops. TFL maintains a list of old stations and lines that are no longer in use. But for the most part, these are inaccessible, and the only aspect people can see are the street level entrances, unchanged, but gated without entry.
Beneath central London, snaking from Paddington to Whitechapel, there is another underground network entirely independent of the London Underground. The Post Office Railway, known as Mail Rail since 1987, was a system that transported post between various sorting offices.
