The reasoning for making it backwards compatible with trolley poles was for the transition. They already made a section of St. Clair (east of Bathurst) pantograph only because they could do so once the 512 was an all-Flexity service.I thought the way the TTC has been wiring the panto compatible system, is that its backwards compatible with trolley poles. So they will never need to convert the heritage fleet to panto. They can still use trolley poles on the panto routes.
As intersections come up for maintenance don't be surprised if other locations become pantograph only because someone realizes it can be done for cheaper once there is no need to support trolley poles in revenue service.
