I think i know why wedal road is part of crossrail. On early plans there was a single roath park station around where the gower hotel used to be. This split to be the better located crwys road (on loads of bus routes and well linked to alot of people), and wedal road roath park. The idea is to run a metro style bus along the a48 from the newport road station, with stops at major overpasses, link to rail at wedal and call at the hospital then on to waun-gron park. In the consultations people proposed that a station in gabalfa would complete the link. It would be a very useful line on the metro map, even if not trains.I would hope that Wedal Road would be called Roath Park because most people don’t have a clue as to where Wedal Road is - although it does give a more specific location than just Roath Park - which is big. I think the station would be on the south side of Wedal Road although it would be a good idea to have the platform as part of the bridge - similar to Waungron Park.
The benefit of Roath Park (Wedal Road) station would be massive as it would be the shortest walking distance into Heath Hospital - especially of they made a new footpath on the south side of the cemetery. (A pity Heath Hospital was not on the site of the cemetery as the station would have been right at the hospital - a mistake not being made with the new Velindre Hospital).
All day long, Wedal Road is rammed with parked cars - presumably from hospital workers.
Surely, this is nothing to do with Crossrail as that is a west > east route from Cregiau/Plasdwr via the City line to Central and down to the Bay and on to Newport Road via Splott?
