The Advanced Passenger Train (APT) was an experimental tilting High Speed Train developed by British Rail during the 1970s and early 1980s, which did not enter regular service.

Superelevation was applied to portions of the BR network, although the angle was limited. Here, a Class 91, based on APT technology, rounds a canted turn on the East Coast Main Line.
In contrast to APT, HST was a huge success and remains in service to this day.
