Productive day today.
Arrived at the diesel shops to find 522 with it's trio of SD40-2(W)'s dropping off it's train.
Passing by the bypass tracks on the Yellowhead, we saw a WB stack train with a pair of SD60's. We relocated to another spot and caught the train departing from Walker.
Hearing 418 coming in on the Westlock, we headed to Dunvegan Junction. 418/419 often rate interesting power. It's certainly not rare to find a SD40-2 or GP40-2 coming in from McLennan for a visit to the locomotive shops. This train didn't disappoint. Granted, it was a 1 hour+ wait for it to actually depart Dunvegan.
While watching 418 entering the mainline, I turn around, and let out a pretty foamy "Holy shit" as 1501 has snuck up behind us.
Acting on a hunch, we head further along the Westlock Sub and sure enough 1501 has proceeded through Dunvegan Junction, and then reversed onto the Westlock Sub. She was moving at a good clip, but, we gave chase towards St. Albert.
We approached the crossing at mile 4.79 hoping we might see the RDC somewhere. Tentative plan was to cut it off at Morinville. No need to. She was just about to return across the crossing when we reached it.
The unit then headed back towards Edmonton, so back towards Dunvegan we head.
The Dunvegan Yard is of course a former NAR yard. Today, all it plays host to are covered hoppers in potash service waiting to be taken to Scotford Yard, as well as some minor CN facilities including this facility where 1501 has been spotted in the past. Knowing that, was why Andrew suggested heading that way in the first place. Well, turns out that was eventually the destination for the RDC, so we got another shot at shooting it. Given that switches needed to be thrown, we had a little more time to shoot it and get our shots.
