Connecting Scotland to High Speed 2 (HS2) must be a priority, according to the Scottish National Party (SNP) manifesto.
The party called for construction of a line connecting Glasgow, Edinburgh and the North of England.
The manifesto also called for full devolution of ScotRail from Network Rail, blaming 54% of ScotRail train delays on issues connected to the infrastructure owner.
“SNP MPs will make a strong case for the full devolution of Network Rail so that we can deliver a more effective and efficient rail service for Scotland,” said the manifesto.
The SNP said almost £6.4bn of infrastructure projects would be under construction in Scotland in 2017/18.
Energy efficiency has been made a national infrastructure priority by the party, with £500M of public funding earmarked for projects over four years.
The party said its oil and gas sector remained ”uniquely well placed” to develop carbon capture and storage (CCS) technology on an industrial scale. It said the UK government had “reneged” on its commitment to a £1bn CCS programme that could have benefitted Peterhead power station - and vowed to secure future funding for the Aberdeenshire project.
“We will work to ensure Scotland is not denied this opportunity by working to secure the funding needed to develop this vital technology here in Scotland,” it said.
The party remains staunchly opposed to the proposed nuclear power station Hinkley Point C in Somerset.
