Remember that earlier discussion that we had about the line speeds? The Grimsby Sub is only 65mph, with a long stretch of 30mph (the Hamilton PSO). The Kingston Sub has a couple of PSOs of 75mph, but is largely 95/100mph track. That alone will account for a substantial amount of time savings.
Which then goes back to the question about improving the line speeds on the Grimsby Sub, and what it would take. (In theory, not much. In practice.....who knows. It's up to CN.)
The other thing to consider is that the timings on the Grimsby Sub also include an allowance for the drawbridge over the Welland Canal. There isn't much that can be done about this, save for figuring some way to realign the line to not require a drawbridge. (Yes, GO has said that they've negotiated an agreement with the Canal Commission to try and keep the bridge clear for the morning and afternoon rush hours, but the fact of the matter is that the bridge will still remain an impediment until it is bypassed.)
I think we're saying the same thing. My understanding was that the question was about how much time would be saved if we had a 140 km/h speed limit without those slow zones. 95 mph is 13km/h more than 140 km/h, but I think the travel times should be ballpark-comparable.
