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. The theme of this weekend is Family Fun so there will be plenty of activities to entice the younger kids in as well as the adults. there will be costumed characters appearing from the past to tell tales from history, family activities and stories of the underground, as well as opportunities to see the different displays. These depot open days take place three times a year, with the next September, so don’t miss your chance!
