Not so long ago, any letter or parcel landing on a doormat in London would have just disembarked from a surprising journey... underground.
Stretching for 6.5 miles in a tunnel deeper than the Tube, the Mail Rail transported post between Whitechapel and Paddington for 75 years until its closure in 2003. Since then, the stalactite-filled
tunnels and abandoned platforms have lain dark and empty. Until now.
The Postal Museum in Clerkenwell has opened part of the Mail Rail to the public; running battery-powered passenger trains on a 20-minute subterranean tour. While the Mail Rail is undoubtedly the star attraction, the museum is a thigh-rubbing joy to wander itself, for its interactive displays (you get to sort post and put your face on a stamp) and fascinating insights into what has kept this great British institution ticking for so long.
