As with other heritage railways, the SVR operates normal services at a maximum speed of 25 mph under its Light Railway Order and Safety case. The SVR and Great Central Railway have permission to operate non-passenger carrying trains at higher speeds under certain controlled conditions.
In addition, several locomotives (such as LNER-designed Peppercorn Class A2 No. 60532 Blue Peter in 2024) have visited for running in and testing at normal linespeed. These visits are not included here.
