37264

The British Railways Modernisation Plan of the 1950s identified a need for a powerful 1,500-2,000hp diesel, designated Type 3. The English Electric company's design was commissioned and the first examples built in 1959. Later renumbered as the Class 37, the type became a jack-of-all-trades, seen hauling everything from heavy freight to express passenger services and over 300 were built. Nicknamed 'tractors' for their noisy engines, a few are still in service on the British railway network despite their age, though most have now retired.

D6964 was built at the Vulcan Foundry in Newton-le-Willows in 1965, becoming 37264 in 1974, and served in South Yorkshire and East Anglia before transferring to Cardiff in 1988 and finishing her almost 35-year career there in 1999.

37264 arrived at the NYMR in 2010 and has been in regular use since. She is currently painted in the 1980s Large Logo blue livery.
