Английская Википедия:British Rail Class D16/2
Шаблон:Short description Шаблон:Use dmy dates Шаблон:Use British English Шаблон:Infobox locomotive British Railways Class D16/2 was a class of prototype diesel locomotives built by British Railways at Ashford Works and introduced in 1950–1951, with a third example being introduced in 1954. They had been designed by Oliver Bulleid for the Southern Railway and were authorised in February 1947[1] but did not appear until after nationalisation. The diesel engine and transmission were supplied by English Electric, but the Bulleid influence was obvious. The box-like body style closely resembled Bulleid's electric locomotives and was quite different from the usual English Electric style, typified by British Rail Class D16/1 which in turn was strongly influenced by contemporary American design.[2]
Unusually for pioneer British diesels, 10201 and 10202 were originally specified (prior to alteration of gear ratios to improve tractive effort when operating as mixed-traffic units) with a top speed of Шаблон:Convert rather than the Шаблон:Convert of 10203,[3] pre-dating the three-figure maximum speeds of the Deltic and Class 50 designs by some years.
Percy Bollen's bogie design[4] and the power train of 10203 were taken almost unmodified for the first ten production British Rail Class 40s but with a more traditional English Electric design of body with prominent noses and louvred side panels.
Operation
The original locomotives, numbered 10201 and 10202, worked services on the Southern Region of British Railways. They were transferred to Camden depot in the London Midland Region in April 1955.
Number 10203 was outshopped from Brighton railway works in March 1954, its modified engine giving a power output of Шаблон:Convert.[5][6] It was trialled on the Southern Region before joining its sisters on the London Midland, being allocated to Willesden depot.
All three locomotives were non-standard with regard to spare parts and servicing, and they were withdrawn at the end of 1963. After spending some time on the scrap line at Derby Litchurch Lane Works, they were eventually scrapped at Cashmore's at Great Bridge in 1968.
