While taking the GO yesterday, I observed a Flexity running around the yard trackage at the new MSF. The blue lights on the emergency power-off stations were on throughout the yard, suggesting that the overhead is live at least in part of the yard. There were plenty of line trucks further south at the wye to the main line, which gave me some confidence that the overhead will be strung as far east as Keelesdale and perhaps beyond soon. So the ability to do run-ins and testing on the vehicles, and perhaps a section of the signalling, is certainly within sight.
We know that some number of Flexities have been delivered, and with so much time left there is reason to believe that more will be delivered by any potential commissioning date. With TTC, Kitchener, Edmonton and Crosslinx all receiving substantially similar vehicles, I'm increasingly optimistic that any common deficiencies or bugs are known. There is enough time remaining that the pace of deliveries and any rework resulting from test results is not really a concern.
That gives me confidence that the availability or operability of the vehicles will not be the limiting factor for when this line opens. Rather it will be some "missing link" of trackage or tunnel/station completion, or both, that sets the limit for when commissioning can begin.
It's not beyond possibility that the western section could be made sufficiently complete to commission the base elements of power supply, signalling, and operation. Perhaps even a "stress test" running full simulated service, at least between Mount Dennis and the next-eastern set of crossovers. That might make the installation and commissioning of the sections further east that much easier, even if it does not permit actual operation.
It's also not beyond possibility for Crosslinx to truck a couple of Flexities across the city if the easternmost segments reach the point where an operational test is possible. Stress testing might have to wait until the line was complete across the city, but some basic elements of testing the signals, data circuits, power supply etc might be possible. Again, that would not enable actual operation, but it might allow many prerequisites to be completed and bugs corrected, even while some other part of the line is still considerably behind schedule.
So, for me it all boils down to watching those big holes in the ground, especially Yonge and Cedarvale.
