Cleethorpes Coast Light Railway, complete with WW1 shrapnel holes in some of the carriages.

Probably also the only railway where a driver once drove off the end of the track and knocked down a privy, luckily an unoccupied one. Not the prettiest route as it wound its way among the chalets at about 5m.p.h., but memorable for the people-watching.

Shame it got closed down, and no, it wasn't because of the privy incident.
