A profile of the Stanier Princess Royal class by David Hunt, Bob Essery and Fred James. Between them these three authors have collated and interpreted thousands of records and documents to bring new light to the design, development, testing and modifications made to this class of pacifics throughout their working careers. A career which, for two of the class, will continue into the future.
Produced in association with the National Railway Museum whose archives contain many of the works drawings and official test documents used to refine the locomotives.
