From time to time, on special days, we organise unusual metro journeys, courtesy of London Overground. Dates to be confirmed.
Meanwhile, on any day you can enjoy the views from the platform at Wapping and look down from the platform through the lighted arches of the old fairground. Before you travel to Wapping, call at Rotherhithe and on advertised days stoop through the narrow doorway to descend into the secret chamber. This is the Grand Entrance Hall, where Brunel nearly drowned. Meet at the Museum for your timed entry into the secret chamber.
Bring a travel card or ticket valid for the journey.
