don't see why we should accept that transit vehicles shouldn't go as fast as possible on their ROWs.
One major reason why this may be is because, on a local transit line (which this is), there is only so much speed you can attain, before you have to slow down again for the next stop. And the higher the top speed is, the longer the braking distance will be, and, paradoxically, the less time the vehicle will spend operating at top speed before it has to start braking.
And no (this is not directed specifically at you, but to anyone who reads this and wants to reply): cutting stops is not an option. This is a local transit project. Transit is not a failure because it serves local needs and isn't a super super fast cross regional super express. People who live along minor roads also deserve higher order transit and not to be stuck in bumpy, uncomfortable buses.
Are the subway slow zones acceptable? Should we accept that it's "faster than a streetcar [the Yonge streetcar it replaced in 1954]," and therefore a great success? If the parameter by the success of a billion-dollar transit investment is judged is "faster than a bus without private lanes" (ie. mixed flow), something's gone horribly wrong with planning and operations.
I don't think this is a 1 on 1 comparison, because the subway slow zones are artificial speed restrictions caused by infrastructure decay. A much fairer point of comparison would be the design speed of line 1. From Bloor to Eglinton West, even in times of good maintenance, it is still relatively slow for a subway, due to the timers and curves on the line. Or, here's the original comment which set off the discussion:
These trains need to be seen outpacing cars.
On Allen Road, do you see the line 1 trains outpacing cars? If somehow they managed to get up to highway speed, they soon have to stop for the next station. Should we remove line 1 from the transit map?
Transit outpaces cars during rush hour in the peak direction, or otherwise in incredibly dense areas with constant, all way, all day traffic congestion like Manhattan. On a suburban stroad like Finch West, this was never a realistic expectation, and is therefore an unreasonable metric by which to judge whether a project is well designed. To have trams outpace cars on Finch West, you'd need to run a super express with little to no stops from Finch West to Humber College.
If we want to saddle our suburban LRTs with stupid operational practices as we have on the 510/512, we may as well have called this the "536 Finch West" streetcar, and set those expectations low.
What operational practices are you referring to? I haven't seen anyone refer to this. All we're talking about is how the line will have the same speed limit as the street it's on, which, if Google streetview imagery is still accurate, is 60 km/h. How is this a problem?
The issue isn't so much the rolling stock as it is the speed of the line. 60km/h is too slow. If we're trying to entice people to get out of their cars, then transit has to go faster. Especially with the amount of money we spent on this project.
Calgary C-train hits an average speed of 80km/h
I don't want this to sound offensive, but to me it sounds like your expectations for transit are entirely too high.
Taking transit (especially in the suburbs) because you want to save time as compared to the car is like expecting every passenger on transit to conform to your own personal behavioural standards. In both cases, you want to take the car to satisfy these expectations, because you are asking something of transit it can never deliver. Unless, again, it's rush hour in the peak direction, or you're in Manhattan or similarly dense urban areas. It is rarely faster to even take the GO train, never mind a local transit line.
