Considering it's apparently on the track for cars needed for repair, might be it for now.
However considering it ran for 3 days, I'd say GO now seem serious about running these things.
No, I saw them all still at Willowbrook on Sunday, all lined up in different locations.
Though 206 recently having been turned to face west tells me we're not far from them entering service.
I believe the odd number consist markers are old leftovers from when GO had the old white and black stop markers, which is why they were never updated (and at certain stations they no longer appear).
Has GO done away with the split consist procedure? Now have noticed them not splitting the consists on the weekend at Georgetown for a few weeks now, and some of the old cab cars have started being used on non split trains, leading.
Seems some have been moved to one of the tracks near the Willowbrook canopy. (not my image)
Don't know if this means they're getting ready to put them in service yet but who knows.
