Calling all trainiacs, lovers of dark underground tunnels, and fans of both! The Postal Museum has unlocked the doors and is inviting you down into the 100-year-old tunnels beneath the museumin special Tunnel Walks tours.
That’s right – a visit to this London museum doesn’t just treat you to spectacular sights, stories, and exhibits. You can quite literally take a step back in time – and underground!
Passionate expert guides lead visitors through the postal tunnels as they share the stories of the staff who built, operated, and maintained the railway. You’ll get to explore the tunnels as you find out about their construction in the early 1900s, through to their prime during the middle of the century, and eventual closure in 2003.
What do you get to see?
The tour lets you explore parts of the railway on foot that are not accessible on the Mail Rail ride. (That particular experience sees you boarding a miniature train through the original tunnels.) During the tour, they’ll take you to an eerie yet fascinating train graveyard, and you’ll be shown the floodgates that kept the workers from harm.
The Tunnel Walks tours give visitors a chance to get an in-depth insight into the workings of the postal tunnels and to explore a unique subterranean environment in the heart of London that many Londoners don’t know about.

Lest you think that a visit to The Postal Museum should start and finish with the tunnel tours, there is much more to see! Interactive experiences and fascinating displays take you back in time through the history of the UK’s postal service.
There’s the above-mentioned Mail Rail subway train, which treats guests to a taste of the tunnel walks (in slightly more controlled conditions). You can also see the world’s first postage stamps, as well as a restored mail coach. It’s a fascinating museum, with a perhaps unexpected wealth of information and history to share. You’re sure to leave with a newfound respect, appreciation, and wonder for the incredible work of the postal service.
