Mail Rail at The Postal Museum takes you beneath London on a small train through tunnels once used to move post across the capital. The railway operated from 1927 to 2003, separate from the Tube. The ride and nearby displays bring its work to life, with historic trains, audio-visual storytelling and a mail-sorting simulator that moves as you sort. The wider museum covers centuries of postal history through stamps, records, maps and photographs. Families can also visit Sorted, the postal-themed play space.
A railway beneath London
Mail Rail was an underground railway used to move post around London from 1927 until 2003. It ran separately from the Tube, linking postal operations beneath the city. Today, the train ride gives visitors a view of the tunnels and railway equipment at close range.
The route is compact, but the journey is part of a larger museum visit. Audio-visual material explains the railway’s role, while interactive displays give you ways to engage with the work beyond simply watching from the train.
Try the mail-sorting simulator
One of the interactive exhibits recreates the physical challenge of sorting post on a moving carriage. The simulator shifts as you work, giving the task an active feel. Other displays and the train ride help explain how mail moved through the underground system.
Historic trains and tunnel views add detail to the story. A guide is available around the ride, and the wait can be a chance to ask questions about the railway or the museum. Timed bookings are used, though boarding can take place later than the slot, so leave a little room in your plans.
Explore the Postal Museum
The Postal Museum covers around five centuries of Britain’s postal history. Its collection includes stamps and objects connected with the Post Office, alongside records, maps, posters and photographs. Some records date to 1636. Exhibits use interactive elements and sculptures to present the history of postal services and communication.
Mail Rail is one part of this wider collection, so allow time to see the museum as well as taking the train. Families can also visit Sorted, a postal play space for children. The small train ride and the play area are both suited to younger visitors.
