The English Electric diesel-electric Type 3 Co-Co now known as Class 37 – Colin Campbell

 

This 1750hp medium powered “go anywhere do anything” loco was perhaps the diesel equivalent of the LMS Black 5 steam engine. Introduced in November 1960 and the last of the 309 built came into service in November 1965. It was perfectly suited to both passenger and freight use and proved to be a very reliable engine. The term Co-Co meant that each bogie had 3 axles, each of which was powered. The maximum speed varies between 75 – 90mph . The introduction of the Class 66 locomotives heralded the large numbers of 37’s being withdrawn but there are still quite a few in use or in store owned by the likes of Colas, Direct Rail Services, DB Schenker and West Coast Rail along with about 40 on Preservation lines. The latest addition to the list of rail operating companies on the national network “Rail Operations Group” are currently completely refurbishing a class 37 which will have the ability to amend the coupling system on the loco so there will be no need to use barrier coaches when hauling any type of stock. It looks like the 37’s will be around for quite a time yet.
