British Rail Class 16

The British Rail Class 16, also known as the North British Type 1, was a diesel locomotive designed and built by the North British Locomotive Company in Glasgow. Ten were produced, numbered D8400 to D8409, after British Railways placed a small order on 16 November 1955 for Type 1 freight locomotives under its 1955 Modernisation Plan. The design was largely derived from the company's earlier prototype No. 10800 and used the road-switcher layout, with an 800 horsepower Paxman 16YHXL engine. The locomotives left Queen's Park Works about a year behind schedule, in the summer of 1958, and were delivered to Devons Road depot before moving to Stratford. Engine seizures, coolant contaminating the fuel oil and non-standard control equipment made them unreliable, no further examples were ordered, and all ten were withdrawn between February and September 1968 and cut up by the end of 1969.
