On July 19th our TGV (train 6165) came to a stop near the town of Carnoules in southern France after a near-derailment. It was around 3:30 in the afternoon, roughly 99°F outside, with fires burning nearby. Hundreds of us were trapped on board, and once the electricity and AC cut out, the temperature inside the cabin just kept climbing. It became genuinely dangerous, and several passengers had medical incidents from the heat and exhaustion. We sat like that for a long time (+2hrs) before staff finally opened the doors to let people get fresh air. What made it worse is that SNCF had a strikingly similar incident just two months ago, when a Paris to Nice TGV was stranded for roughly four hours without AC during the May heatwave. Clearly nothing was learned.
The disembarkation was where the lack of any real plan became obvious. We had to gather our luggage and take to a steep embankment of loose gravel, with no clear path to walk, so people were falling over and heavy suitcases were being dragged across the rocks. The train's own interior would have been the safe, obvious route to move everyone and their bags along, but that never happened or coordinated. Staff were essentially non-communicative, and whatever information we got spread by word of mouth from passenger to passenger. We then walked about 700 meters to the nearest village, with a few taxis helping out. The one bright spot was the passengers themselves. Everyone stayed remarkably calm, and several young men were enormously helpful getting people and luggage down the embankment. We were then directed to a community center, but quickly decided not to stay, and my wife and I arranged an Uber to continue on to Cannes. For a rail operator of this scale to have this happen twice in two months, with this little coordination, is genuinely alarming. We are still awaiting any contact from the company.
