Join one of our trained volunteers for a conducted tour of the engine house, including one of the Triples. The tour lasts approximately one hour and will take you up to the top of engine No.7, so you will need a head for heights! Your guide will explain the intricacies of the triple-expansion steam engine and how it works and you will also go down to the ram and turbine floors to see the Triples from below, the 1933 steam turbines and the fascinating mercury arc rectifiers.
Tours are usually limited to 8 people per group. We regret that children less than 1.4m (56in) tall will not be allowed on the engine tour for health and safety reasons. You will need to be able to climb stairs and steam engines tend to be oily, so please bear this in mind when you go on the tour. We regret that there is no disabled access to upper levels of the Triple or to the ram and turbine floors.
You can book your place on the tour in the lobby when you arrive or, if you are part of a large group, email to book in advance .
There is no charge for the guided tour, although the museum would appreciate a donation at your discretion.
