Can I just add to this discussion that there IS a plan for an additional stairless exit from Platform 2 in the pipeline.
I did mention this on another thread, I believe the PV thread.
Funding is/has been sought, and now comes the design and concept of it. But just to put minds at rest, there is a plan.
I believe the idea is for the far end of platform 2 to exit straight into the PV car park, allowing disabled and car commuter access.
