Calling the 2013–15 upgrades a disaster is not the same as calling the Trillium Line [as a whole?] a disaster.Don't agree. They were supposed to cut headways from 15 to 8 minutes. They spent twice the money the original line cost, ran random service for a few months, then settled on 12 minutes. There used to be 2 vehicles doing the route in 12 minutes providing 4 trips an hour, then 4 vehicles travelling the route in about 16 for 5 trips per hour at twice the operating cost. The average wait was reduced by a couple of minutes and the average trip length increased by the same. For 50 million dollars. Then they scrapped the original vehicles that could have run several years longer. Great value for money.
A marginally longer trip time is not "disastrous".
Also, the original vehicles are actually still sitting in the yard. They intended to sell them for scrap after no one would buy them for other uses, but no one even bought them for scrap.
The story of their retirement pretty much amounts to the fact that it was impossible to get any new ones, and they had already been wanting one to increase the spare ratio anyway.
I'll also just point out that despite the original price tag being $21M, there was additional spending in the 13 years that followed to upgrade the line. Reworking the Ellwood diamond, welding the rail, purchasing the corridor from CP, etc.
"it will need to be completely rebuilt to accommodate a second track"The problem is that the line needs to be shut down for very long periods (months to years) to perform any sort of upgrade. They have said that to improve frequency modestly to 10 minutes requires replacement of the Walkley overpass. But there are further complications. Because Walkley Station is being designed as a side station, it will need to be completely rebuilt to accommodate a second track. Yet another lengthy shutdown is inevitable. We simply have a poorly designed line that has not been futureproofed. I am not sure how you gain public confidence if we keep needing to shut down the line every few years. We gained ridership when both Line 1 and 2 were opened at the same time, but that lasted a mere 6 months.
Really? Is that really what you think?
Walkley will have side platforms. Why would the other side need to be "completely rebuilt"?
