A high-speed TGV train running between Strasbourg in eastern France and Paris derailed on Thursday, injuring 20 people including one seriously, local officials said.
A spokesperson for the SNCF said: “As far as we know, there are no serious injuries among passengers.”
Other trains were being re-routed and there was no interruption to services, the spokesperson added.
In 2015, a TGV derailed on the Paris-Strasbourg line during a test run prior to the line’s entry into service, killing 11 people.
That crash dealt a setback to the rollout of high-speed rail lines that are a symbol of French pride and intended to help support economic growth beyond the capital.
