The Class 16 diesel locomotive was ordered under the Modernisation Scheme as a Type 1 locomotive for the Eastern Region; based on prototype No. 10800. Only ten were ever built and were completely incompatible with virtually every other fleet. This class was troubled by poor reliability and was scrapped relatively early.
The engine was a Paxman 16YHXL with 7 in (178 mm) cylinder bore and 7.75 in (197 mm) cylinder stroke. The traction motors were 4 x GEC WT 441, nose suspended with single reduction gear drive. The Main Generator was a GEC WT 881and the Auxiliary Generator was also of GEC manufacture.
