France’s railways are taking off. The National Assembly, prompted by President Macron, last month passed a bill to ban internal air services whose routes could be better served by trains. Short-haul flights will be halted in cases where a rival rail service can speed passengers between cities in less than two and a half hours. 

The aim is to cut France’s carbon footprint, but the effect will only be felt on a small number of high-speed routes, such as Paris-Lyon, Paris-Nantes and Paris-Strasbourg.
