Outlines of Power - Nº 2: The Metrovick Co-Bo's

Here we have the second of the 'Outlines of Power' articles by Mike Turner that the magazine 'Rail Enthusiast' ran during the early 1980s. 
This one featured the Metrovick Co-Bo's or Class 28s as they were classified under the TOPS system. The accompanying annotation reads as follows:
Mike Turner has painted Metropolitan-Vickers Co-Bo diesel-electrics D5709/10 with the "Condor" fast fitted freight headboard that was often carried by the type in their early days.
The Metrovicks were introduced in 1958 and their Crossley V8 two-stroke engines produced 1,200 bhp at 625 rpm continuous rating. The Co-Bo axle design allowed the use of five Metropolitan-Vickers 180 hp axle-hung, nose-suspended, traction motors to be used and this, together with 3 ft 3½ inch driving wheels and an all-up weight of 97 tons, resulted in an impressive tractive effort of 50,000 lbs - exactly the same as a "Deltic".
