There is a report that Elon Musk is planning to build a very high speed transport system between London, Birmingham, Manchester and Scotland. The system is known as Hyperloop. It would operate at 1,000 km per hour. The journey time between Birmingham and London would be 14 minutes. It is claimed that this can be built at one tenth of the cost of conventional high-speed rail.
The system is claimed to be faster, safer, cheaper, and use less land, than conventional high-speed rail.
