Engine
The engine of the Class 45 was a marine type slow revving diesel, a Sulzer 12LDA28B with a bore of 280 mm and a stroke of 360 mm. This gave 22 litres per cylinder or 264 litres for the whole engine. The unit was turbocharged and intercooled and gave 2500 hp at 750 rpm. The engine was of the double bank type with two parallel banks of 6 cylinders, geared together to a single output shaft. Six-cylinder versions of the engine were fitted in the Class 25 locos (amongst others) and eight-cylinder versions in Class 33s. Class 45s were the updated versions of the Class 44 locomotives, the latter having a 2300 hp non-intercooled version of the same engine. i.e. the 12LDA28A. The later Class 47 had a modified version of the same engine, a 12LDA28C.

“There is a small steam engine in his brain which not only sets the cerebral mass in motion, but keeps the owner in hot water.”
