As well as trains, the place is chock-a-block with signs, old ticket machines and other memorabilia ripped out of stations that have been refurbished. You can also take rides on the Depot’s miniature railway, which features steam & electric trains and full size heritage vehicles.
For the weekend they are also running trips on the Wootton Electric Tramway, brought over from the Isle of Wight, which will carry visitors along its own tracks around the Depot powered by overhead electric wiring.
To continue the London’s Transport in Miniature theme there's loads of working model railways from professional and amateur modellers. A must see is John Polly’s Abbey Road model (pictured below), a fictious London Underground station which is split over a level four platform station and based on Charles Holden's designs.

If you're going along IanVisits has some handy tips.
Buy tickets in advance - they last all weekend, and avoid the often lengthy queues on the door.
If taking a bag, make it a very small one as larger bags have to be left in the cloakroom. My camera bag just happens to snugly fit in their airport style measuring box - so I don't have to queue up to get my bag back when leaving.
