There's a map on this link

which includes the line to Creigau that in fact goes on to Talbot Green before joining the Swansea to Cardiff line at Pontyclun. There's also stations planned for Ely Mill, Culverhouse Cross and Rhoose and stations called Newport Road and St Mellons for east Cardiff, but it seems to me that a lot of existing stations (including Ninian Park) have disappeared!
They are turning that line into a walking/cycle path this autumn

So much for me thinking it would be part of this elusive "metro" system
