I don't think this line was ever double apart from a short section where sidings ran alongside at the Kidderminster end. It looks like the viaduct over the River Stour and canal may have been built with widening in mind however but Bewdley Tunnel was definitely only ever single. The single track might suffice however for an hourly National Rail service as long as that section was under NR signalling control, but I wouldn't want colour lights to take over Bewdley station as the SVRs most interesting signalling installation with its two boxes and AB section through the platforms. Hence I propose a branching chord (yellow) before Bewdley onto the Stourport alignment (orange) where a new 'parkway' station could be established near the A456/B4195 bypass roundabout which could help support options for housing development in fields nearby. A station on the former British Sugar site near Hoobrook to support nearby housing development would be a mistake in my opinion because it would be midway along the shared single track section, with impact on occupancy times and thus capacity and reliability for both NR and SVR, although a new passing loop might be built at this former sidings site to help alleviate this, at considerable cost however. For my Bewdley Bypass option I would also consider extending the line further, partway along the old Stourport line then branching off southward across fields (yellow) to make a new approach to the town centre near the River Severn bridge and Basin with a new terminus in the car parks thereabouts. It looks like such a route might be possible without any significant demolition. Station area signalling at Kidderminster and Bewdley would thus remain SVR administered mechanical as now with slots working to the NR control of the single line between. the shared single track would be about 3.8km in length or 2.4 miles. Even at a typical heritage speed of under 25mph this should be possible to traverse in under 10 minutes so an hourly NR service should be easy to accomodate amongst the heritage traffic. At commuter peaks, when there is usually no (or only limited) heritage running, the NR service could be strengthened to half hourly, although that might require an extra passing facility on the new branch. I'd envisage Stourport trains to be Birmingham - Kidderminster stoppers extended.
