THE first-ever summer open weekend for young visitors and their families is being held at London Transport Museum Acton Depot on July 7-8.

Rarely open to the public, it will give visitors the opportunity to see where the majority of the museum’s vast collection is housed.

Children can discover, learn and play as they explore a treasure-trove of more than 320,000 artefacts from London’s transport history.

Highlights include badge-making, using science to design a new Underground tunnel, a costumed character from the past bringing stories from the underground to life, vintage bus rides, model layouts and souvenirs and gifts from the depot shop
