What To Expect From The Mail Rail

Londoners now have a chance to ride a tiny, cramped, train under central London!

“But… I do that every weekday?!” I hear you say.

Not like this you don’t, welcome to the Mail Rail! A secret tunnel network that used to carry London’s post 22 hours a day.

Mail Rail

A Quick History

In 1911, facing congested roads and unacceptable delays, the Royal Mail had a radical idea. They built a 6.5 mile underground railway between Paddington and Whitechapel to carry letters.

Mail Rail

The route had platforms just like the tube today, serving major sorting offices through central London.

Post would be loaded into tiny (2ft wide) carriages to be shuttled through the city, an efficient system which carried over 4 million letters a day in their 1930s peak!

Mail Rail

This all lasted until 2003, when Royal Mail announced using the service was round 5 times more expensive than trucks (though workers disputed this). Mail Rail, as it was known since 1987, was mothballed and the tunnels lay unused.

Until now.

Going Underground

The Postal Museum opened in July 2017 and launched the Mail Rail experience in September, meaning you can now traverse the secret underground system!

The trains are pretty cramped, two can just about squeeze next to each other, but there’s no leaning on the doors. Like the tube today, you’ll stop the train and get a driver announcement, much to the ire of your fellow passengers!

Off We Go!

Along the 20 minute ride, there’s a wealth of interesting things to spot, all pointed out by your guide and ex-mail rail employee; Ray Middlesworth.


A surprise was the fantastic projections.

They bring the abandoned platforms to life with stories through the ages; anecdotes of power failures, when the River Fleet burst into the tunnels and the 1943 bomb that crashed onto the tracks. Our disembodied guide Ray proudly tells us that the Mail Rail was up and running the very next day!

Fun fact

The idea for a subterranean network was first dreamt up by the Victorians. From 1863, mail travelled around 3m underground propelled by air pressure in self-driving metal cars along rails. It ran until 1866 then again between 1873 – 74, but was later abandoned.

The system was only for mail, but that didn’t stop some daredevil Victorians…

In 1863 The London Journal reported that a lady “whose courage or rashness – we know not which to call it – astonished all spectators, was actually shot the whole length of the tube without injury to person or petticoat!”
