Changes

When the SVR began operations in 1970, the line was still subject to the 17 tons 12 cwt axle weight restriction. This meant that large locomotives such as [[61994 The Great Marquess]] could not be used until a program of upgrading the line had been undertaken. The successful completion of this means that the SVR has since hosted a GWR 'King' class locomotive, as well as similar classes of locomotives from other companies. However sections of the line such as [[Victoria Bridge]] remains remain subject to operating procedures which restrict the double-heading of locomotives.

The Light Railway Order under which the SVR operates specifies a maximum speed of 25mph for normal services. [[High speed testing|Operation up to 50mph ]] may be carried out between Kidderminster and Bewdley when the railway is closed to the public; a recent example being the testing of Metropolitan Railway 0-4-4T No 1 in 2012 prior to its participating in the London Underground events in 2013.
