You don't think that the TTC might be forward planning for 750V all around? Remember it was TTC staff I spoke to who told me the change was to accommodate higher voltage.
Just *imagine* the size of the series resistor you would have to install to drive one of those 600V motors with 750V ;-)
Modern motor controllers can be quite tolerant of significant voltage variation. However, I doubt they're changing the voltage.
