Beneath the bustling streets of London lies a unique piece of the city’s industrial heritage: the Mail Rail. Originally known as the Post Office Railway, this driverless, narrow-gauge railway was built in the early 20th century to transport mail quickly and efficiently between major sorting offices across the city. Construction began in 1915, but due to the disruptions of World War I, the railway only opened in 1927. For 76 years, the Mail Rail operated tirelessly, shuttling letters and parcels through six and a half miles of tunnels, until it was finally closed in 2003 as road transport became more practical for the Royal Mail.
Today, the Mail Rail has been brought back to life as a fascinating visitor experience. Travellers can board a specially designed miniature train and journey through the very tunnels that once formed the backbone of London’s postal system. The ride lasts about 15 minutes, taking you through dimly lit passageways and past original station platforms, all while immersive audio-visual displays recount the stories of the workers and innovations that kept the mail moving beneath the city. It’s a rare chance to see a side of London that was, for decades, hidden from public view.
The Mail Rail experience is part of The Postal Museum, a vibrant institution dedicated to the history of communication and the postal service in Britain. The museum itself is a treasure trove for history enthusiasts and families alike, featuring interactive exhibits that trace the evolution of the postal system from its origins in the 16th century to the present day. Highlights include a beautifully restored 18th-century mail coach, the world’s first postage stamp – the Penny Black – and a collection of rare letters and artefacts that bring the story of the post to life.
Visitors to The Postal Museum can also enjoy hands-on activities, such as sorting mail on a mock-up train carriage or exploring the Sorted! play area designed for younger children. Temporary exhibitions and special events add further variety, making each visit unique. Whether you’re a history buff, a curious traveller, or simply looking for an off-the-beaten-path London adventure, the Mail Rail and The Postal Museum offer a memorable journey through the city’s hidden past and the vital role of communication in shaping society.
