That reminded me of the time I was the chase vehicle when we roaded a Terex scraper, don't recall the model but it was a pretty good size machine believe it had a 12-71 Detroit. We ran it around 170 across New York State on US-20. This was no new machine and the three of us doing the move had never seen it before the day we left and the two drivers who took turns had never run one before! One image in your picture that rally brought back a memory was seeing those railroad tracks. We were running through a town, actually right near where the three of us grew up, and while going flat out, forget but that thing did move pretty fast for it's size, came upon a set of tracks across a fairly new section of road so no thought about them being that rough. Well when the front end hit the tracks and bounced all of a sudden there was a squealing of tires sounding like a 747 making an emergency landing on short runway. The machine bounded a few more times with more squealing of tires. Luckily there was a wide shoulder and the driver pulled over and stopped. When we asked why he stopped so fast he said "I didn't! Then we noticed it would not shift gears. Shut it down and it would not restart. That's when we found out one of the cables had come off the battery. This thing had an electric shift Allison and when he hit the tracks it must have caused a interruption in the power to shifter causing it to go from high gear right to low gear causing the machine to slow down way too fast. Surprisingly all we had to do was clean up the cable clamp and reatach and it was as good as ever. For about a year after that you could still see the skid marks on the road!
