Construction of the South Europe Atlantic high-speed line (HSL) will provide a continuous high-speed rail link between Paris and Bordeaux. With trains travelling at a cruising speed of 320 km/h, the two cities will be only two hours apart. Works started in 2012 and commercial service will start in 2017. The challenge: to build 340 km of new line (including 38 km of connecting lines) between Tours and Bordeaux in just five years, on an alignment that passes through 113 municipalities, six departments and three regions. This exemplary project will drive development and boost the attractiveness of France’s southwest regions.
