The experience of riding in the Rail Mail train at the London Postal Museum is a joy for any age (unless of course you suffer from claustrophobia). From the excitement of seeing the little train arrive to getting in (it’s a pretty tight squeeze for two adults side by side as these carriages were designed for mailbags, not people)then riding through the tunnels, sometimes only centimetres away from the walls.Watch an audiovisual history on one of the platformsbefore returning to base. You can even sit in the engineer’s train and press some switchesbefore moving on to interact with more exhibits. I enjoyed seeing engineer John Scott’s toolbox made from an old mail carriage, look at all those tobacco tins lined up and labelled.
