French rail network fully restored after Olympic-day ‘sabotage’

France’s national rail operator says repairs to its network damaged by sabotage attacks were “fully completed” and there would be “no more delays” for travellers from Monday after widespread chaos before the Paris Olympics opened.

The situation on the main western line from Paris was “practically normal” and “three out of four” high-speed TGV trains were running on the main northern line from the capital city “without any increase in travel time from now on”, railway company SNCF said in a statement on Sunday.

Transport Minister Patrice Vergriete had also said on Saturday that services would be normal by Monday. He said security on the network was strengthened, with 250 personnel and 50 surveillance drones deployed along with police helicopters.

The attacks raised security concerns as Paris hosts the world’s largest sporting event. While an investigation is under way, the authorities have not identified the perpetrators.

“Who is responsible? Either it’s from within, or it’s been ordered from abroad, it’s too early to say,” Interior Minister Gerald Darmanin told France 2 television.

There has been no immediate claim of responsibility for the widespread disruption.

SNCF had said on Saturday it had partially restored services, but there were widespread delays and cancellations. It said its agents worked through the night in adverse weather conditions to improve traffic from the north, east and west to Paris. As of Saturday morning, normal service had resumed on the eastern high-speed line.

“On the north, Brittany and southwest high-speed lines, seven out of 10 trains on average will run with delays of one to two hours,” SNCF said.

Despite the disruptions, SNCF said all transport for Olympic teams and accredited personnel will be maintained as planned.

The coordinated attacks staged in the early hours of Friday saw cut and burned fibre optic cables running along the tracks that transmit safety information to train drivers.

The attacks were well-planned and carried out by the same organisation, a source close to the investigation told the AFP news agency.

SNCF estimated that about 250,000 passengers were affected on Friday.

Many travellers were on their way to Paris for the start of the Olympics, while others were hoping to travel in the opposite direction to start their summer holidays.
