Among the vehicles on display at the London Transport Museum is the first underground electric train, which had no windows because there was nothing to see underground. The trouble was that no one could tell which stop they were at, a glitch resolved by employing an athletic announcer who ran to each carriage at every station, shouting out the stops. Dating from 1890, this is one of several museum exhibits you can board. The design gallery is a tribute to Frank Pick, the man responsible for rolling out the London Underground brand and giving each line its own character. For children, the London Transport Museum has an under-fives play area decorated with Steven Appleby illustrations and the chance to sit in the driver’s cab of a red bus and guide a Northern Line simulator through tunnels and up to platforms – (truth be told, it’s fun for adults, too).
