Great footage, thanks David. it appears they overshot the dumper when spotting loaded train. Possibly to introduce slack in the train so the rotating couplers will function properly ?
@@davidrayner9832 creates terrible train dynamics when coming in hot, can cause ongoing issue for the train holding holding devices when dumping that entire train
No, the car positioner is seen at 26s. The thing on the end of the train is a pair of compressor-brake cars. The compressor keeps the brake pipe charged to normal pressure so the brakes on the train are released and also keeps the brakes on just those two cars to provide a little resistance and keep the train in a stretched condition so it doesn't run in and out every time the positioner moves it along. It'll move two car lengths 120 times during a dump and if there were no resistance, the whole train would bang and crash continually. Once, in around 2008, a train came in minus two cars and no one told the dumper opertor so he dumped the usual number of cars which meant the last dump was the compressor-brake cars. With nothing for the barrel's grippers to hold on to, they fell down the hole and it's a very deep hole. It took several weeks to get them out.
