Cardiff metro: Rhondda Cynon Taf transport corridor plan
A planned metro-style train system for Cardiff and its surrounding areas would regenerate south east Wales, it has been claimed.
Cardiff council's cabinet member for strategic planning and transport, Graham Hinchey, said the £4bn network would improve transport links in the city and make it easier for people to travel without a car.
The proposals also include reusing an old line from Fairwater to Creigiau and improving links to Llantrisant and Pontyclun.
Mr Hinchey spoke to Oliver Hides on BBC Radio Wales.
