I bet if the Welsh Government had its way then we'd have three trains per hour for Cardiff to Holyhead!
As for Manchester-South Wales, I'd like to see it sped up but would it be worth adding Nantwich to the hourly pattern, at the expense of a few of the smaller stations between Shrewsbury and Cardiff?
Nantwich is only 35 miles from Manchester (57 from Birmingham via CRE) and has a population of 17,500 making it the 4th largest settlement after Shrewsbury/Hereford/Cwmbran between Newport & Crewe- the hourly Manchester trains should all stop there. It has the best potential for traffic growth.
