Group exploring the tunnels

Get exclusive access to Mail Rail’s tunnels, tracks and platforms whilst The Postal Museum is closed to the general public, exploring parts of the railway that aren’t accessible on the Mail Rail ride.

We’re opening up the 100-year-old Mail Rail tunnels for exclusive underground walks that will allow you to discover one of London’s best-kept secrets. 

Expert guides will tell the surprising stories about the staff who built, operated and maintained the underground railway over the course of 100 years – from its construction in the early 1900s, through the heyday in the middle of the century, to the eventual closure in 2003. 

Access Information

The route involves walking on uneven ground in low-light conditions for around 1.2km (0.75 miles) including stepping across rails and up onto platform areas. For this reason, the walk is not accessible by wheelchair users and is not recommended for people with mobility impairments.
