courtesy of WikipediaThe British Rail Class 14 is a type of small diesel-hydraulic locomotive built in the mid-1960s. Twenty-six of these 0-6-0 locomotives were ordered in January 1963, to be built at British Railways Swindon Works. The anticipated work for this class was trip working movements between local yards and short-distance freight trains. The good all-around visibility from the cab and dual controls also made them capable of being used for shunting duties. The order was expanded from 26 to 56 in mid-1963, before work had started on the first order. They were numbered D9500-D9555.
The Class 14s, like many other early types of diesel, had an extremely short life with British Railways, in this case not because of poor reliability but because many of its envisaged duties disappeared on the BR network a few years after they came into use. BR started to dispose of members of the class from mid 1968, the entire class had been sold to industry or scrapped by the end of 1970. In their new careers in industry many had a working life of two to three times greater than that with British Railways. The industries in which they were employed, such as coal mining, declined during the 1970s and the class again became surplus to requirements. Several have found a third lease of life on preserved lines where they are ideal for both light passenger work and the maintenance of permanent way.
Unusually, D9504 was leased in 2005 from its preservation group and found itself in revenue-earning service on the newest mainline in the UK – High Speed 1 (known as the Channel Tunnel Rail Link during construction) – mainly in marshalling and stabling the 450 metre, 22-wagon concrete-pumping train on the final stretch to St.Pancras Station.[3]
D9524 was re-engined under the ownership of BP Grangemouth – it was later re-engined again under the ownership of the Scottish RPS who, following BR practice, gave it a number of 14901. It now operates with a Rolls-Royce DV8TCE (640 bhp).[4]
The last locomotive built, D9555, was the final locomotive to be built for British Railways at Swindon Works, in 1965; today the locomotive is privately owned and operates on the Dean Forest Railway, Gloucestershire, its original route.
