I lived in the minning back in 80s of Pilbara had different mining companies which Cape Lambert had robe river iron associates and mt Newman mining Co in Port Hedland and Mt Goldsworthy mining Co from Mt Goldsworthy and Shay gap and Hamersley iron ore mining company
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.
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 ?

Wow ~ what an amazing bit of engineering . -Nate
I can imagine what a monday morning could throw in my face there...
I wish i could come to Austrailia. The mining sector is where my heart is as it regards to career interest.

Hello David. I would like to know what is the machine on time 00:48 ? Is this a Autonomous Machine to position Wagons into Car Dumper?

do you know of anywhere I might find even a basic drawing for those ore cars?
Not really.
S series? All built in China

No, the driver just overshot it. The shunter uncoupled and the dumper pulled the train back into position.

4 minutes of nothing 1 minute of car dumping
It's a process that takes around 3 hours. Want me to film the whole thing and bore you with it?
@@davidrayner9832 Take 'em for a tour of CD1.
Just found it! ha. Worked down that shitpit more times than I care to remember.
Wanna be a engineer don't work here lol
