OO ROG CLASS 37 COCO 37510 ERA 11

Entering service as the English Electric Type 3, the British Rail Class 37 diesel locomotives were built at the  Vulcan Foundry in Newton-le-Willows in a Co-Co configuration, based on  locomotive designs for export markets. Built to undertake both freight  and passenger work across all BR sectors, these engines proved highly  reliable and, after overhaul, many survived in service across the  network into the 1990s.

British Rail first placed an order  for forty-two Class 37 locomotives in January 1959, the first of which  was delivered in November 1960, entering service on 2 December with the  last of this original batch complete by mid-1962, by which time  subsequent orders had been placed. The last of the 309 locomotives built was delivered to the Western Region on 9 November 1965, originally  numbered in the range D6700-D6999 and D6600-D6608. Many Class 37  locomotives were refurbished in the 1980s, extending their life. As a  result, the Class 37 remains in service to this day as one of the  longest serving classes on British railways.

Second-hand  locomotives have been exported to railways in France and Spain whilst in the UK many locomotives no longer required to work have been preserved. Rail Operations Group operate a fleet of 6 locomotives built between  1961 and 1963. They have been modified to allow them to move EMUs around the network including modifications to allow them to couple with and  operate the brakes on various EMU classes without the need for  translator vehicles. Built in 1963, the locomotive was initially  numbered D6883 but became No. 37183 under TOPs in 1974.

The locomotive was renumbered to 37884 in 1988 having been upgraded to  class 37/7 specification. 36884 was purchased by Europhoenix in mid-2013 and painted in Europhoenix livery in mid-2014 before being leased to  the Rail Operations Group (ROG) from 2016.
