The London Transport Museum at Convent Garden has closed for a while whilst it undergoes a refurbishment thanks to a Lottery Grant, so the depot where they normally store the bits that aren't on display has been opened up for a couple of weekends a year.

You don't have to be a train spotter to enjoy it, especially if you have travelled on the underground for a number of years...
