Tickets to tour three disused disused tube stations go on sale on Wednesday morning.
On offer are the now familiar tours of the disused station at Aldwych, and repeats of the access tunnels and disused platforms at Charing Cross.
However, very rarely open to the public, will be the famous Down Street station.
Visitors to the Railway Executive Committee’s bomb-proof bunker will be able to see where the nation’s railways were coordinated and Prime Minister Winston Churchill took refuge in secret at the height of the Blitz. Located in Mayfair between Hyde Park Corner and Green Park stations, Down Street had a short life as a working station from 1907 to 1932.
I visited the station recently.
Visit the disused Jubilee line platforms closed to the public in 1999.
However, you also then divert through a door in a passageway to walk through hidden service tunnels, and walk underneath Trafalgar Square towards the fourth plinth, and see the station from a different angle from the bottom of a ventilation shaft.
Familiar to regular subterranean visitors, this is the former Strand station and was the terminus of the little used shuttle line to Holborn.
Tickets can be booked from here at 10am on Wednesday morning.
