Remarks: I arrived at Collier on September 4th while Q400's power was making its final backup move into the yard, and a few minutes later the train departed, giving me a good look at the lashup in its entirety. ES40DC 5400 and SD40-2 8204 appeared to be doing all the work, followed by AC4400CW 298, ES40DC 5368, Road Slug 2262, and slug mother GP40-2 6431 in tow.
