First introduced on British Railways in September 1962, the class was initially known as the Hawker Siddeley Type 4, later Brush Type 4 and finally Class 47 under the TOPS system. A total of 512 were built in a unique arrangement between the designers Brush Traction Ltd and BR. Brush constructed 310 locomotives and supplied equipment to Crewe Works where the other 202 were built. The earliest Brush Type 4s were allocated to the East Coast Main Line; gradually the class spread across the length and breadth of the system, ultimately coming to serve on all Regions of BR. Deliveries took nearly six years to complete, the final example not entering service until May 1968.
After some early teething troubles had been overcome, the Class 47s settled down to become highly reliable and capable performers on all manner of duties. All were built with vacuum brakes; train air brakes were fitted to later examples from new, and to earlier locomotives as they passed through works. The majority originally carried steam train heating apparatus. Electric train heating equipment was fitted only 22 of the class from new, although eventually 263 were to receive it as the use of electrically heated stock increased. With the decline of steam heated stock came the removal of steam heating equipment from most of the locomotives that had been fitted with it.
Apart from accident victims the class remained intact until 1986 when the first programmed withdrawals took place. Since that time there has been a steady erosion of their numbers as their former duties have been progressively taken over by more modern forms of traction. The sectorisation, and later break up and privatisation of British Rail, led to the ownership of the surviving members of the class being transferred to private companies. The decline in their numbers has continued, yet more than half a century after the first one entered service, it is still possible to see Class 47s at work on the main line as a small number remain in the service of present day train operating companies. However, it is in preservation that the long term future of the class can best be secured.
