The Severn Valley Railway is a standard-gauge heritage railway in Shropshire and Worcestershire, England. The 16-mile (26 km) single-track line runs from Bridgnorth to Kidderminster, calling at four intermediate stations and three request stops ("halts"), following the course of the River Severn along the Severn Valley for much of its route, and crossing the river on the historic Victoria Bridge. Train services are hauled by a mixture of steam and heritage diesel locomotives and are often composed of restored heritage carriages, though goods trains are run on special occasions. The railway operates most weekends and holidays throughout its running season, it also holds events featuring more intensive operation, such as steam and diesel galas.
