'Evening Star' was the last steam British Railway locomotive to be built.  This BR Class 9F, designed at Derby under the direction of R. A. Riddles, was built in 1960 at Swindon. This was British Railways’ final and probably their most successful design.  A total of 251 of this class were built to haul heavy freight traffic, but when required, they successfully worked express trains such as the “Pines Express.”  

 

"I am sure it has been truly said that no other product of man's mind has ever exercised such a compelling hold upon the public's imagination as the steam locomotive. No other machine in its day has been a more faithful friend to mankind nor has contributed more to the growth of industry in this the land of its birth and indeed throughout the whole world... Those who have lived in the steam age of railways will carry the most nostalgic memories right to the end."  

R. F. Hanks – March 18, 1960 - Swindon, Wiltshire, UK at the naming ceremony for the ‘Evening Star.’

RIDDLES CLASS 9F 2-10-0 (Locomotives in Detail)

by David Clarke

 

The single largest class of new locomotive to be constructed after the Nationalization of Britain's railroads in 1948, the 251 representatives of the Riddles-designed Class 9F 2-10-0 were amongst the most powerful steam locomotives ever constructed in the United Kingdom.  First introduced in 1954, these impressive locomotives were destined never to fulfill their true potential as, in 1955, the Modernization Plane foreshadowed the complete elimination of steam traction from Britain's railroads. Construction of the class continued until 1960, when No 92220 Evening Star became the last main line steam locomotive to be constructed for use by BR. By this date, however, it was clear that the class was destined to have a relatively short life and, by the final withdrawal of main line steam in August 1968, many of the class had been withdrawn after less than a decade in service.  Designed primarily for heavy freight traffic, where they performed superbly on services such as the iron ore duties from Tyne Dock to Consett, the '9Fs' were equally at home on passenger turns. Amongst the lines that were to see the class regularly hauling passenger trains was the ever-popular Somerset and Dorset line between Bournemouth and Bath.
