The only thing wrong here is that the SRT is on it's last legs and past its lifespan, with no realistic plan for the implementation of its replacement in the foreseeable future.

Orion V Posted September 26, 2019 Report Share Posted September 26, 2019 I'm just throwing this idea out and can't remember if it was answered before. I read Translink will retire the 95 batch of Mark Is in 2021-2024. There are exactly 20 units which consists of 5 trains of 4 sets. Why can't TTC buy this batch then refurbish it to use on Line 3 now that the Line 2 extension has been delayed? And if it's not enough, get some from the 91 batch. The 95 batch was not rebuilt so TTC can rebuild it to their liking and are a decade newer so it should last TTC another decade pending the completion of Line 2 extension.

One reason is that McCowan is overfilled as it is right now, and adding to the fleet will only make things worse. Its operating at full capacity right now.

What if we split our fleet and couple in a Vancouver car, so there are 2 cabs per train, (one on each end), and 2 non-cab cars in the middle? (C-V+V-C, Similar to the Crosstown design (kind of).

They could also berth trainsets in McCowan station overnight. Link to comment Share on other sites More sharing options...

The yard can hold 2 more trainsets than currently operated, but with the storage of Work cars, the max. amount of cars to be acquired by the TTC would be 8 individual cars, then the yard would be 100% full. I've always heard stories of it being filled. Link to comment Share on other sites More sharing options...

I don't know if there are compatibility issues or whatnot, just thinking out loud. While the cars are operated in pairs, there are no physical limitations preventing them from running as single cars (unlike the subway cars). So what you are suggesting is possible, yes. The bigger issue, however, is that the Skytrain cars are not in any better condition than the cars used on the SRT (and in fact may be worse, as they have higher mileage), and that each car's VOBCs has been upgraded to a different spec than the TTC's. And, of course, there's the issue with buying 30+-year-old used equipment.... Dan 2 Link to comment Share on other sites More sharing options...

The only thing wrong here is that the SRT is on it's last legs and past its lifespan, with no realistic plan for the implementation of its replacement in the foreseeable future. Well, the fact that it's been used hard since day one and kept going well past any reasonable service life has caused the Scarborough RT to turn into a clapped out piece of junk for sure but there are a number of questionable design decisions with the system. The big one to my mind which is an inherent wrong I think is the linear induction motor. Half the motor is literally left out exposed to the elements. Rain, snow, freezing rain don't directly affect the reaction plate between the rails directly because it's a passive component, it just needs to be there in order for the system to work but it doesn't do anything by itself other than heat sink waste energy when there's no load on the line to absorb regenerative braking output, but precipitation accumulates on it and it's in very close proximity to the live part of the motors on the underside of the cars. This along with the side running third and fourth rails for power collection are susceptible to problems from precipitation. The power rails freezing up means loss of power but generally no huge damage. But snow and freezing rain in particular have had a long history of damaging motors on the trains. So, what to do? Raising the motors on the trains and giving a larger air gap to provide more clearance is an idea except that knocks down how tightly coupled magnetically the motors are to that reaction strip which means more power consumption and heat generation. In the early days, they had serious problems with motors overheating. The solution to that was to lower them, make the air gap smaller, and get much better magnetic coupling to the reaction rail to reduce power consumption and heating but that makes the problems caused by accumulated precipitation much worse. No matter which way you go on this, you lose badly. To me, that's an inherent design problem. Link to comment Share on other sites More sharing options...

yrt1000 Posted September 28, 2019 Report Share Posted September 28, 2019 Forgive me if I sound a bit crazy...bear with me here. I’ll try and explain this as best I can. I know the TRs have a sort of hum or buzz to them at all times, but has anyone else noticed that some of the TR sets are, well, louder? I’ve been commuting for work the past 3 months now, and I’ve noticed over the past few weeks that maybe, I dunno, 1/3 of the trains I ride have this sort of constant loud, high pitched sound. Kind of sounds like the higher-pitched hum the TRs have when they start to accelerate. But it’s at all times, whether stopped or moving So does anyone know what I’m talking about or am I legit going crazy here, haha Link to comment Share on other sites More sharing options...

You get the carrying capacity of an LRT without the flexibility, but with the separation requirements and costs of a subway minus the capacity, along with a serious dose of single source supplier vendor lock-in on practically everything involved, and because it's all proprietary, it comes with a heavy cost premium. In terms of obtaining a lose-lose-lose outcome, nothing else comes close. Link to comment Share on other sites More sharing options...
