On the Midland Hotel, Jonathan climbs over 240 feet up the immense clock tower to explain how Britain had different time zones until the advent of stations like St Pancras. He discovers water powered elevators, why penthouses used to be on the ground floor and how the hotel was almost doomed to failure by only providing 9 bathrooms for 400 bedrooms.
