Remarks: My final catch at Collier Yard on September 19th turned out to be a surprise double feature. Q400 arrived around 3 PM and spent a little while shuffling around the yard, making setouts. Just as Q400 was reassembled and ready to depart, a northbound intermodal (a very late L174 I think) sailed past on the other main behind ES40DC 5299, ES44AC 771, and C40-8W 7726. The big train slowed significantly as it passed under Halifax Road, and as its tail end approached Q400 began to gather a little speed out of the yard. ES40DCs 5222 and 5270, SD40-2 8122, AC4400CW 386, and SD70MAC 4786 led Q400 under the bridge just as 174's last containers rolled past, and the pair continued their chase into the distance past BX.
