Pontypridd rail passengers on commute squeeze
The new Wales rail franchise holder will be held to account on issues like punctuality, cleanliness and service quality - or they will not get paid.

The winner - also new South Wales Metro operator - is expected to be unveiled in the next 24 hours.
Welsh Government ministers are discussing final details on Tuesday.
