TSR intends to extend south beyond Horsehay & Dawley station to Doseley Halt, build a new bridge over the A4169 and continue to the Ironbridge Gorge passing through Coalbrookdale and eventually onto the power station site at Buildwas. South of Doseley half a mile of trackbed and two missing level crossings separate TSR's current railhead from the A4169 and Lightmoor Junction. Permission was given in June 2014 by Telford & Wrekin Council for trains to operate south to Doseley once all trackworks and building works have been completed. It is expected for work to commence south from Horsehay & Dawley station to Doseley Halt in the summer of 2015.
