The land for the up platform at Pershore is still available but there is currently no access as the land behind the platform was sold off.
The current plan is to add a new car park on the up side at the east end of the station. A footbridge is available to link the car park but it is steps only no ramps or lifts.
Disabled parking would be on the existing small car park adjacent to the existing platform on the down side.
The problem with the task force proposal to double to just west of pershore is that there would then be a requirment to provide another footbridge with ramps or lifts.
Much cheaper to just keep the existing single platform and double to just east of the station.
No need for a passing loop so not realy a Penryn solution sorry S+TE
