The coordinated arson attacks on the French railway system that disrupted train service across northern France and beyond on Friday morning were expected to upend travel plans for about 800,000 customers, the national railway company said.
Here are the train lines facing delays and cancellations on Friday:
LGV Atlantic, the national high-speed line connecting Paris to France’s Atlantic coast.
LGV East, the national high-speed line linking Paris to Strasbourg, on the German border.
LGV North, the national high-speed line extending from Paris to Lille and the Belgian border.
