The Postal Museum and Mail Rail

A family day out split across two buildings on Phoenix Place. Start at Mail Rail, the narrow-gauge postal railway that carried post under central London until 2003, where visitors take a short ride on a miniature train through the old tunnels. Across the road, the Postal Museum covers around five centuries of communication history through interactive exhibits, a mock-up mail train carriage where children can try sorting post, a restored mail coach, and rare stamps including the Penny Black. There is also a separate Postal Play Space that needs its own ticket. A café with highchairs sits in the welcome area. Booking ahead is advised, and the venue suggests planning two to three hours, or about four during school holidays.
