The London, Midland and Scottish Railway (LMS) Princess Royal Class is a class of an express passenger steam locomotive designed by William Stanier. They were Pacifics (i.e. had a 4-6-2 wheel arrangement). Thirteen examples were built at Crewe Works, between 1933 and 1935 and two are preserved.

Overview

When originally built, they were used to haul the famous Royal Scot train. Two batches were built; a first batch of two, and a second batch of eleven, including a single example of a version using steam turbines instead of cylinders (No.6202) - which was in its own, separate class. They were withdrawn in the early 1960s in line with British Railways' modernisation plan.

Each locomotive was named after a princess, the official name for the class was chosen as Mary, Princess Royal was the Commander-in-Chief of the Royal Scots. However, they were known to railwaymen as "Lizzies", after the second example of the class named for Princess Elizabeth who later became Queen Elizabeth II of the United Kingdom. Later examples of express passenger locomotive built by the LMS were of the related but larger, Princess Coronation Class.
