Snaking 70 feet below ground, from Paddington to Whitechapel, lies one of London’s most hidden secrets – a historic underground railway system. Part of the UK’s industrial heritage, Mail Rail is an integral part of the story of how the Post Office has continuously explored pioneering ideas to speed mail delivery.
The Mail Rail is not listed, but it is a heritage asset; it provides an insight into a unique system and its inner workings. Mail Rail was mothballed in 2003, when it became more efficient to use road transport. Since then, a team of the original engineers have maintained the system. The stations remain, and parts of the tracks are still used (by London Underground and more recently Crossrail). Some equipment and machinery has been removed, but the spaces left behind have remained largely untouched for over a decade.
