If you make the SRT high platform LRTs and thus different technology than the rest of the LRT system you might as well save a billion dollars and just upgrade and refurbish the SRT with newer trains like they have in Vancouver, WHICH IS WHAT THE TTC SAID WAS THE BEST OPTION MORE THAN A DECADE AGO!One of the problems with the SRT conversion was that it was meant to be compatible with Transit City - the same low floor LRVs that are now running in Waterloo Region. This was so it could share the same maintenance centre at Sheppard and Conlins Road as the Sheppard East LRT. The idea was poorly pitched all-around. If built correctly, (with the Malvern extension and a better terminal at Kennedy) it would have been a major improvement.
The LRT should have been planned as a high-floor system, reducing the work necessary to rebuild the SRT stations. It would have been quite distinct then from Transit City. You could then pitch it as a distinct, high-speed system, and could have called it a light metro to appease the blockheads. By virtue of running underground, the Eglinton-Crosstown LRT escaped the Fords' wrath and will open in two years or so.
The replacement of the TTC's Scarborough RT has a tortuous history, and one that isn't entirely settled yet. We look back at what it has taken to get to this point, where a subway extension continues to be a point of contention.
