Network Rail apologises as more commuters are stranded

It's been a week of misery and chaos for rail commuters. Passengers were left stranded again, today, because of cancellations and delays.

The disruption was caused by signalling problems at Slough - and between Twyford and Maidenhead. Routes through Reading station to Paddington were badly affected.

Today, Network Rail apologised for the problems. Cary Johnston talked to Dan Panes of First Great Western - which is likely to get an extension to its franchise.
