With some 400,000 objects housed here it could take a lifetime to see everything at London Transport's Acton depot, so this family weekend offers a nice chance to interact with some of its most choice pickings. As well as the rare chance to explore the collection a wide range of activities will be on offer, including make and take craft workshops, miniature railway rides, heritage bus trips and, for the grown-ups with driving licenses, the chance to take a taxi test drive, including driving in a full circle. Go on, you know you want to. And if you're keen to take home some rare memorabilia, you can do that too; model buses will be on sale, as well as Metropolitan line luggage racks. Tickets are valid on both days, and are bookable in advance at 020 7565 7298 or online.
