I watch long videos on my TV (45 min - 1 hr) and YouTube has the audacity to shove minute+ long ad reels in my face every 15 minuets, claiming “fewer ads for this long video.” Bullshit. I have learned however that if you go to give feedback on the ad and flag it as inappropriate, it skips all the ads in that reel and sends you right back to the video! I can get past unskippable ads in a few seconds this way.
I was on this train. Amtrak paid me a settlement not to sue them, but it’s not Amtrak I blame, it’s BNSF, who owns the track. It’s very clear from the camera footage that the track was badly misaligned by the time the train went over it at 80 mph. That line is one of the busiest in the country, and if the freight locomotives (one of which had gone over that section of track barely an hour prior) had some kind of monitoring system, they would have alerted all the other trains to stop or slow down. I used to love riding trains, but our rail infrastructure is much too far behind places like Europe.
I’ve heard of a diesel-electric logging truck that uses this concept as well. Use the batteries going up the mountain empty, charge them again going downhill loaded.
