Urgent need for new transport links from Scotland as rail group propose ideas to strengthen the union A series of key improvements to the UK s rail network has been proposed to the government in an effort to strengthen the union . The High Speed Rail Group (HSRG) submitted seven transport improvements to Sir Peter Hendy’s Union Connectivity Review that they believe will safeguard the strength of the UK economy. Among the ideas are upgrades to the existing Glasgow/Edinburgh to London and Birmingham/Manchester to Glasgow/Edinburgh to add capacity and reduce journey times. The proposals also call for an extension to the Borders railway, offering a useful diversionary route from Carlisle to Edinburgh.
