Into ghost stations? Visit on Friday for a fascinating talk by disused station expert Siddy Holloway. The Secrets of the London Underground co-host will share clips from the TV show and answer your burning questions about the tube network's abandoned bits. There's also a load of bite-size lectures running all weekend, with topics ranging from transport art history to station architecture.

Original station signs, moquette fabric scraps, genuine tread plates — just a few of the authentic tube treasures you can pick up for bargain prices in the London Transport Museum shop in the Depot, where collectors can also get their hands on just-released model locomotives. Meanwhile, the Friends' Shop is home to a range of secondhand transport ephemera.

Whilst this month's programme of talks is more suitable for adults and older kids, there's still plenty to keep the little ones occupied. That includes storytelling, tube tile-themed arts and crafts, an explorers' trail and — the pièce de résistance for tiny trainspotters — a go on the London Transport Miniature Railway.
