Capacity is a function of frequency. They don't need 3 mins on each Western branch. But they absolutely need 3 min headways on the central portion. And given that Orleans has a single line/branch, they need 3 min frequencies at peak too. The 4 mins right now, in the East, is proving inadequate. They clearly need 3 mins right now.
Also, with branched service in the West, assuming a 1:1 ratio on each branch, means peak service will be half of mainline at each branch. So any headways higher than 3 mins on the trunk, mean greater than 6 mins on the branch. Go to 4 mins on the trunk, and it's 8 mins on the branch. Similar to Trillium today. This is what people don't get. Past the split, the Confederation Line looks a lot like the Trillium Line in the West and Southwest.
