But the return ride that evening was even more spectacular, as Mayflower was joined by The Duke of Gloucester, a British Railways Standard Class 8P locomotive built at Crewe Works in 1954. Saphos Trains, the operator, responded:

“Designed by Robert Riddles to handle heavy express services between London Euston and Scotland, Duke of Gloucester was conceived as the prototype for a new generation of Standard Class 8 express passenger engines — though it ultimately remained the only one ever constructed.”

Building on the success of Riddles’ previous Britannia Class 7 locomotives, the Class 8 design included a three-cylinder layout and the sophisticated Caprotti valve gear system, which enhanced steam efficiency.

However, design and construction flaws, particularly with the exhaust system, prevented the engine from attaining its full potential. In 1962, after only eight years of service, it was scrapped.

The Duke of Gloucester Steam Locomotive Trust rescued the locomotive from Barry Scrapyard in 1974, after it had been abandoned.

A 13-year restoration ensued, during which engineers repaired the original defects and transformed The Duke into the powerful, free-steaming locomotive it was originally meant to be.

Withdrawn again in 2012 for a significant repair, Duke of Gloucester has since undergone extensive restoration work and will triumphantly return to mainline service in 2024, once again demonstrating the excellence of British steam engineering.”

Mayflower is a steam locomotive that was built in 1948 as part of the LNER Thompson Class B1 and assigned the number 61306.

She is one of the few remaining members of this adaptable type, which served across Britain’s railway network and was designed for mixed traffic.

According to Saphos Trains, the Mayflower was named after the legendary ship that transported the Pilgrims to America in 1620. It mostly hauled passenger and freight trains in the Eastern region.

Known for her dependability and efficiency, she exemplified the pragmatism of steam locomotives in the postwar age.

Mayflower, which was taken out of service in 1967, was maintained and later restored to operating condition.

Her striking apple-green livery and robust performance have made her a darling among steam fans, preserving the B1 class legacy while also demonstrating the elegance and engineering excellence of Britain’s steam era.”
