Not normally open to the public, this is a fantastic opportunity to see some the hundreds of thousands of items stored in the working museum storehouse. These depot open days take place three times a year, with the next in July and then September, so don’t miss your chance! The focus of this open-weekend is Love your Line, so you can see vintage vehicles, posters and learn about the creation of the lines as well as the communities thats urround them. There will be a series of themed activities for children and adults too including talks and special displays.

Tickets must be booked in advance and children under 18 go free!
