Between Bing Siding and the Flashbutt Yard, Speno Rail Maintenance Australia appear to be testing / commissioning their new RG5 rail grinder, which is an RR36, meaning 36 grinding wheels with serial M36A. It is between RG3 and RR48 and RG4 another RR36.
BHP Iron Ore use Speno and Loram for rail grinding activities to enhance operational performance of their rail line and wheel wear.
Here's a panorama image of FMG's eight SD90MAC-H2 units stored out of service down the south end of the Thomas rail yard. From left (port) to right (mine) are 910, 911, 912, 917, 913, 914, 915 and 916.
From studying images, it looks like both 912 and 916 have the engines removed, while 917 is partially stripped. Also, other items have been removed, like handbrake mechanisms and no doubt other 'bits'.
There was a rumour these units are to be scrapped.
