The Old Dalby Test Track is a railway in the United Kingdom which is used for testing new designs of trains and railway infrastructure. It runs between Melton Mowbray, Leicestershire and Edwalton, on the course of the Midland Railway's route between Kettering and Nottingham which closed to passengers on 1 May 1967, and to goods in 1968. It is 13.5 miles (21.7 km) in length.

The Advanced Passenger Train (APT) was a tilting high speed train developed by British Rail during the 1970s and early 1980s, for use on the West Coast Main Line (WCML). The WCML contained many curves, and the APT pioneered the concept of active tilting to address these, a feature that has since been copied on designs around the world. The experimental APT-E achieved a new British railway speed record on 10 August 1975 when it reached 152.3 miles per hour (245.1 km/h), only to be surpassed by the service prototype APT-P at 162.2 miles per hour (261.0 km/h) in December 1979.

Superelevation was applied to portions of the BR network, although the angle was limited. Here, an InterCity 225, based on APT technology, rounds a canted turn on the East Coast Main Line.
In contrast to APT, HST was a huge success.
