French rail operator SNCF said Tuesday that 90 per cent of high-speed TGV trains across the country will not run on Thursday, when unions kick off an open-ended strike against a planned pension overhaul.
The SNCF expects 90 percent of regional trains as well as those on suburban lines in the Paris region will also be cancelled, while international services will be "severely disrupted".
"Thursday is going to be very difficult for our clients," SNCF spokeswoman Agnes Ogier said at a press conference.
"We ask our clients to cancel their trips or postpone them if they are able."
