The UK is one step closer to a super-fast transport system after four potential routes have been short-listed fro Elon Musk's Hyperloop One project. The US start-up has disclosed a list of 35 routes in locations around the world vying to put near-supersonic rail transit system to the test. In the UK, four routes have been picked, that could see lines built from London to Edinburgh, Liverpool to Hull, Glasgow to Cardiff or a'Northern Arc' across a series of northern cities. The London-Edinburgh scheme was led by an Edinburgh University team that has plans to take the route via Birmingham and Manchester. If selected, it would mean travelling between the two capital cities would take just 45 minutes, and the journey from London to Manchester would take only 18 minutes.
