Tim and Siddy are heading to a stunning station you won't find on modern-day tube maps - Dover Street, now known as Green Park. During the Second World War the abandoned passageways and lift shafts of the original station had an incredible second life as the base for the London Passenger Transport Board whose essential work kept London's transport moving against all odds.
