London mini postal train

At London’s Postal Museum (15-20 Phoenix Pl., London, England, WC1X 0DA, U.K.; phone +44 300 0300 700, www.postalmuseum.org), visitors can ride on a more-than-100-year-old underground postal railway in replica miniature trains.

A 15-minute ride on the “Mail Rail,” located 70 feet under the former Mt. Pleasant Royal Mail sorting room, is in cramped conditions (carriages are 51 inches from floor to canopy and 31 inches side to side), with portions in total darkness.

Museum and rail open 10:30 a.m.-6:30 p.m. Thurs. and 10:30-5 Fri.-Sun. Adult, £16 (near $21.50), or child, £9.

Correction Notice: This article has been updated to reflect that vistors to the museum will be riding in replica miniature trains.  The original article did not make this distinction.
