A restored 1938 art deco Tube train will return to service in Buckinghamshire and London next month.
The heritage four-car train will run special journeys from Amersham to Harrow and Watford between the 5th and 7th of September, including a rare trip along the North Curve line.
London Transport Museum says the event marks 200 years of railway history and celebrates the golden age of travel.
The train, complete with moquette seating and art deco fittings, served London for five decades.
