Rail electrification: 'I see the whole line being done'

Transport Secretary Patrick McLoughlin has said he hopes electrification of the Great Western rail line to Swansea can be completed by 2020 or 2021.

It follows a Network Rail report which said the London to Cardiff upgrade would be completed by 2019.

Visiting Cardiff Central station, Mr McLoughlin said he understood the "frustrations" of not having electrified the line 20 years ago.

He said they were "catching up" after previous governments failed to invest.
