Built between 1962 and 1968, the Class 47 Co-Co Diesel-Electric locomotive was once the most numerous class of mainline diesel in Britain with 512 examples. 310 locomotives were constructed by Brush in Loughborough, and the remaining 202 at Crewe. The locomotives were used for passenger and freight operations.

In 2020, 24 of the class remain operational on the national network with more in storage and an additional 31 preserved. Locomotive 47593 entered service in November 1965, running under the pre-TOPS number D1973. The advent of TOPS classification resulted in the locomotive receiving the number 47272 which it kept until 1983 when it was first named 'Galloway Princess' and re-numbered 47593. The locomotive's name plates were removed in 1994 followed by being re-numbered to 47790.

In the summer of 2020, now under LSL ownership and having regained the Galloway Princess name, the locomotive operated many of the Rail Charter Services first class Skipton to Appleby return services on the Settle to Carlisle line.
