David Cameron was shown the busiest section of railway in Wales, near Cardiff Central station, where the electrification of the Great Western main line and the Valleys lines will intersect.
The Prime Minister was shown round by Mark Langman of Network Rail Wales.
The Welsh Liberal Democrats say the decision to hand control of the Wales and borders rail franchise to the Welsh Government demonstrates their influence in the Westminster coalition. But Plaid Cymru say the railway track itself should have been brought under Welsh control.
Eluned Parrott also said she was "absolutely delighted" that the Welsh and UK Governments had resolved the funding of Valleys lines electrification. Plaid Cymru's spokesperson, Rhun ap Iorwerth also welcomed it as a "good step in the right direction" but said his party would continue to argue for complete Welsh control of the railway.
The Welsh Conservatives have blamed a lack of attention to detail by Labour ministers when Valleys rail electrification was first announced for the row over money that put the entire project at risk. Originally the UK government expected the entire £460 million cost to be repaid by the Welsh Government, primarily by increasing train fares.
Under the new deal announced today the UK Government will contribute £230 million to the scheme, though the rest of the money will still have to be repaid.
Network Rail say the go-ahead for rail electrification in the Valleys will mean a better train service and boost the Welsh economy.
Arriva Trains Wales has responded to today's announcement that the UK Government will pay £230 million towards electrifying the Valley Lines.
