TTC: Other Items (catch all)

[kvvoyage]

Not too sure where to put this, but after a service disruption this morning due to "emergency rail repairs" Kipling-bound Line 2 trains seem to have slowed down after leaving Warden once again.

Didn't they do a closure in this stretch to do track work?

It did wrap up after the numerous weekend closures and Kipling bound trains did return to a normal (or quicker?) speed after leaving Warden for a bit

Isn't all the new wiring panto-only now instead of the pole-and-panto hybrid plan that had them adding ears to all the frogs? That throws a wrench into the "switch to the pole and inspect the panto later" backup plan...

A lot of it is, but not all of it yet.

That said, in an emergency, the pole can be (carefully) used on pan-only overhead with the help of someone following along, watching and guiding it. The shoe doesn't need to be on the overhead - the entire pole is conductive.

Huh?? That doesn't sound correct at all probably only necessary at switches and if the streetcar had to revers with the pole up otherwise the shoe would follow the wire

Not true at all the pole is non conductive the only part that is the piece of carbon in the shoe that makes contact with the wire, The pantographs also use carbon on the conductive suffice as well

So will this weekend closure of line 1 address the davisville slow order?

Not so sure about that.

Seen by me - one of the old CLRV streetcars became stopped with its pole under a section isolator, it was stuck - until another car came from the other direction. The operator of the other car used the rope to position the pole of the stuck car against the overhead cable outside of the section isolator, and the operator of the stuck car was able to move forward to the point where the pickup shoe would no longer be under the section isolator. It struck me at the time that the operator on the outside of the car had not positioned the shoe on the other wire, just the side of the pole in order to make the connection. So obviously, the pole was conductive at the point where he placed it against the overhead wire.

Check your information. Trolley bus poles are fibreglass, as you don't want to create a short by having a dewired pole touch both lines.

Streetcar poles are steel, and have been forever. That's why they bend and don't break when they fail.

Dec 15
The Kipling surface west entrance is finally open with access to/from it in all direction.

There is a milling n]machine on site now and not sure where it will be milling unless they plan on redoing the kiss-ride and cab parking area. Until that area is fully clean along withe the removal of everything store on it, milling and paving cannot happen and most likely happen some time this week.

Looks kike it happen some time this past week.

The section isolators don't have power. It's basically a section between two sections of power lines, that's why they would have signs for the drivers to proceed without power and only coast through them.

what's your source on this? I've seen one of the maintenance team replacing a broken pole on one of the new streetcars one time by Spadina and Queen's Quay and it definitely wasn't steel. The poles being steel would be very dangerous if they made contact with the wire as they would conduct electricity to anyone who touches it,

My source?

The TTC. And having actually handled a pole.

As in the trolly pole at the back of a streetcar?
Maybe I was wrong about it but it sounds dangerous to me to have it be a conductive material as it can still touch the wire above if you aren't careful when handling it.

I think there is a difference between streetcars and trolley buses. See: "A trolley bus uses two overhead wires to draw power with two trolley poles, while a streetcar (or tram) only needs one overhead wire as it uses the rails as the return path, meaning it only needs one trolley pole to collect electricity; essentially, a trolley bus is a bus that runs on rubber tires powered by overhead wires, while a streetcar runs on rails and is also powered by overhead wires but only needs one wire due to the track acting as the return path." As long as the streetcar is on the tracks, it is grounded.
