The Postal Museum in Central London reveals the surprising and fascinating story of the first social network. There’s a lot of hands-on stuff for younger visitors and the exhibits are presented in a child-friendly fashion.
The highlight of the Museum is the Mail Rail, a 15 minute ride in a converted train along a stretch of the now disused Royal Mail underground network. The carriages are a tight fit so probably aren’t a good idea if you suffer from claustrophobia (they were originally designed for the movement of sacks of mail and not people).
In its heyday, the underground mail system handled 4 million letters a day. The trains ran everyday 4 minutes, 22 hours a day, seven days a week.
Your ticket gives you unlimited visits for a year (Mail Rail not included after the initial visit).
