Saw something interesting today.
Noted 1023/ 1024 heading south at Grey Nuns. Ran back into that pair Downtown at 100 St as they were heading for the 102 St stop. Watched them crossover from the westbound track to the eastbound track, taking the preferred routing.
Came out from Horton's and find the same pair stopped, while going back through the same crossover, so crossing over from the eastbound track to the westbound track. Not good. It seems it was a sudden stop as the train was partially in the 100A St crosswalk, and not fully pulled up to the lights at 100 St as per normal. After sometime, they switched ends and took the train back into the 102 St stop.
Could speculate on a lot that could have gone wrong, but, without much more than what I saw, there's simply too much that could have happened. I guess it's good that whatever the reason is, it occurred during testing.
The other crossover at 100 St is back in use. Rails nicely polished.
