THIS April, for four days only, London Transport Museum’s Depot in Acton will open its doors for people to explore its collection of posters dating from around 1905.

From Thursday to Sunday, April 21-24, Art of the Poster open days are part of the BBC’s Art That Made Us festival.

Visitors will have the chance to go behind the scenes in the depot’s poster store - usually closed to the public – and enjoy talks, creative workshops and family activities.

London Transport Miniature Railway will also be running on the Saturday and Sunday for passengers to hop aboard replica models of Underground trains used on the Metropolitan line between the 1920s and 1960s.

The London depot houses more than 320,000 artefacts, including historic Tube trains, buses, trams, maps, signs and a collection of more than 30,000 posters.

The depot shop will be open and refreshments will be available.

Timed tickets must be booked in advance online. Adult tickets cost £15 and tickets for children £7.50. Those aged three and under go free.

People living in Ealing, Hounslow and Hillingdon can enjoy a third off tickets. Visit
