TTC: Streetcar Network

Why is UT so obsessed with pantographs?
Because we haven't ever seen one in use in Toronto. It's something that was planned on about 30 years ago when the CLRVS and ALRVS were being designed but things changed due to cut backs and we stayed with the tried and true trolly poles of old.
 
My fantasy streetcar route change is the most modest of all: swap the western ends of the 514 and the 504. This is intended to reduce the track capacity issues at Dundas West and Broadview, improve passenger distribution between the 514 and the 504, and improve line management by equalizing headways.
Hang on. There's already capacity problems between Gerrard and Sumach in AM peak, and you want to reduce service?

The capacity is not reduced. A 30-metre streetcar every 6 minutes is more capacity than a 15-metre streetcar every 4 minutes.

While that's true, the schedule used to be a mix of 15-metre and 23-metre cars southbound almost every 2 minutes. Though the capacity issues really only rear their head, when they can't pull that off.

Here's a look at Broadview and Gerrard southbound in spring 2015, when capacity problems were quite evident when I used to head downtown sometime after 8. As you can see there were about 18 cars an hour (supposedly using some ALRVs) compared to 25 cars in the lighter used 7 AM to 8 AM, and 25 cars from 9 AM to 10 AM (ignoring the 5 heading to the yards - Greenwood/Queen).

And here's after 514 started in November 2016, when it was actually working better. 24 to 26 vehicles an hour steadily from 7 am to 10 AM.

So how's it doing now? My schedule hasn't had me out that early there yet. 14 cars an hour from 7 to 8. 15 cars from 8 to 9. 13 cars from 9 to 10. History tells us that's not enough, and I don't think any of these are ALRVs.

If you look at Queen and Broadview, it improves, presumably as the 504 buses are joining then (have they forgotten last year's lesson that it works better if the 504 buses enter along Gerrard?). But there's still only 15 cars from 8 to 9 AM.

Presumably, it's a disaster currently. 4-minute Flexities are probably the minimum.

Why is UT so obsessed with pantographs?

Personally I could live with poles indefinitely, if doing so diverted money towards accelerating installation of new track switches so the cars could run through without stopping/slowing

Maybe one reason for a RFP for 100 (not 60) additional new low-floor light rail vehicles (AKA streetcars), on top of the current 204 Bombardier order. See link.
It's not an RFP. It's not even an RFQ. It's an RFI. That's a long, long, way from an RFQ.

Photographs make going through switches easier. What you currently see being installed is all tempory. Once they are ready to go all Pantograh they will remove the switches and crossover connections and the wires will just intersect with each other. Poles need a switch of their own to guide it through where as a pantograph only needs to make contact with the wire.

There is a very clear explanation of all this on Steve Munro's site. https://stevemunro.ca/2017/09/12/pantographs-up-on-harbourfront/
