I thought 48,000 was the ultimate capacity with 90-second service. Which will require significant upgrades to reduce dwell times, including a second platform at Bloor Station, and upgrades at the terminals.where in the world did you get 48,000? Everything I've seen is the TTC is planning for a design capacity of about 34-36,000 on Line 1 following ATC upgrades.
Sure, the shorter trains on the Ontario Line can meet the required capacity about 10 years after it opens. But what about 40 years after it opens?
