What is Mail Rail?
Located across the road from the exhibition galleries and café, Mail Rail is a small train which runs underground. Initially designed to transport mail, Mail Rail reveals the story of the postal service’s subterranean world beneath the streets of London.

Ride and exhibition
- See the unchanged station platforms, deep below Royal Mail’s Mount Pleasant sorting office.
- See and hear the people who worked on it, experience their lives below ground and glimpse hidden parts of the railway that once kept the mail coursing through London for 22 hours every day.
- Discover interactive exhibits that bring to life more than 100 years of postal engineering.

The ride
Descend into the one hundred year old former engineering depot of Mail Rail – the Post Office railway – and board a miniature train into the original tunnels.

Audio-visual show
Take in a theatrical experience that travels back in time to the railway’s lively 1930s heyday. Our award winning audio-visual presentations will guide your way.

Mind your head!
Mail Rail was designed to carry mail, not people. Check Ride accessibility to see if a ride on Mail Rail is right for you.

Interactive exhibits
From sorting mail on a Travelling Post Office, to seeing the curious inventions that inspired it all, our fun filled displays get you even closer to the action.
