Before assuming anything of the sort, maybe you need to look at the basic facts - such as there isn't the track capacity available on the single-line section between Norton junction and Evesham west junction, even before you get to things like needing signals to allow trains to turn back at the high-level platform at Parkway if there were big enough gaps in the Cotswold Line service to allow it.
There are all sorts of things you could do if the supply of funding was limitless, but there are far bigger investment priorities in the Worcester area than this, notably modern signalling and a sensible track layout, without all the single-line sections.
Trains to and from Parkway will inevitably be quicker than the central Worcester stations as they don't need to go to Droitwich, call there and negotiate the junctions there and at Bromsgrove. Journey time will be 30-35 minutes for Parkway-New Street journeys, compared with 40 to 45 minutes on the fastest Shrub Hill/Foregate Street services to and from New Street.
No, because you didn't go back into post 616 and edit it so that that anyone else reading it can clearly understand which part of it is a quote from Parallel's previous post and which bit is your response to that quote.
The station is costing £22 million - the facilities are a bit more than basic.
