Money saved from the cancellation of rail electrification between Swansea and Cardiff should be used to fund transport improvements in Wales, MPs have urged.
A report by the Welsh Affairs Committee, entitled The cancellation of rail electrification in South Wales, calls on the Government to not use the money on projects such as Crossrail 2 or the Northern Powerhouse.
The committee points to a "stark gap" in funding between Wales and other parts of the UK, and says the cancellation of the electrification scheme has had a "demonstrable economic cost to the areas affected" and "left local people and businesses feeling badly let down".
The report notes that electrification of the Swansea to Cardiff line would not have made a "significant" improvement to journey times unless the line was straightened, but says electrification would have brought other benefits such as fewer emissions.
It recommends that the Government considers the case for straightening to enable trains to run at higher speeds, and warns that it should "carefully" consider the merits and potential costs of the proposed Swansea Bay Metro.
