The Severn Valley Railway is famous for its fleet of steam trains and preservation of railway heritage. Preservation started on the Severn Valley Railway line in 1965 when a group of railway enthusiasts formed the Severn Valley Railway Society in Kidderminster. Over its many years of operation staff have built up significant skills, experience and equipment to enable the preservation, refurbishment and maintenance of a large fleet of locomotive trains and rolling stock.
Built in 1989 the boiler repair shop at Bridgnorth station is a purpose built building with boiler maintenance and construction of boilers in mind. Named in memory of George Knight, a Deputy Chief Boiler Inspector of British Railways (London Midland Region), new generations of boilersmiths are still carrying out the very techniques George passed down to the early Severn Valley boilersmiths. At the time of installation compressed air to the boiler repair shop was powered by a small Atlas Copco compressor and a larger Broomwade piston compressor.
