Winter refurbishment works 2018-19
Borle Viaduct (Bridge 21) carries the SVR over Borle Brook. Like other bridges on the Severn Valley Railway, it was built with the capacity for dual tracks but only ever installed for single line running.
The viaduct is 42 yards in length, with four arches of 25ft span. The viaduct has suffered from mining subsidence over the years. Regular re-ballasting to overcome this has resulted in the line now being above the original parapet walls<ref>From The Window, Severn Valley Railway</ref>. Although originally there was no edge protection on the viaduct, sets of post and rail fencing were added.
During winter of 1976-77, tie bars were inserted in the viaduct to strengthen it as part of the program to upgrade the line for heavier locomotives. The work was carried out with the assistance of the [[Manpower Services Commission]]. Intense cold and heavy rain brought work to a temporary halt while a large slip at [[Sterns]] and the collapse of part of Bridgnroth [[Bridgnorth]] station car park were dealt with. Services in early 1977 ran for some weeks between Bridgnorth-Highley and Bewdley-Arley until work on the viaduct was completed<ref>SVR News 42-43</ref>.  During winter of 2018-19 contractors were appointed for the first phase in renovating the structure, which was showing fresh signs of water penetration. Planned work involved removal of the fill material down to the existing concrete “flaunching” to allow any degradation to be treated and some additional drainage discharge points provided, an application of high specification sealer and layers of new imported fill material. The works included the replacement of the fencing with more appropriate steel tubing fencing as used elsewhere on the SVR.<ref>Bond C., reported in SVR Forum 7 December 2018</ref>
