Princess Coronation Class Locomotive No 6233 Duchess of Sutherland was built in Crewe Locomotive Works by the London Midland and Scottish Railway Co. Ltd. and entered service in July 1938. She was active for the next 25 years until her retirement from active service in 1963. In 1996 she was purchased by the Princess Class Locomotive Trust and in 1998 a complete overhaul was commenced which eventually wound up costing over one-half million Pounds Sterling. The reconstruction was completed in 2001 and the locomotive is again seeing service and is expected to be active until 2007.
