Miscellaneous TTC Discussion & Questions

Personally, anything that's regularly above 100 dBspl sticks out as a big problem so I checked a reference table and that puts you between jackhammer and jet engine sound levels and comfortably above the threshold for long term hearing damage and even further above the point where hearing protection's recommended.

Obvious to say, but this must be why most GO SuperLo ops wear ear plugs, those things are very loud in the lower deck. I don't know what it is but I'm curious as to why they are like this, because their predecessors have essentially the same engine but way quieter. And its not dissimilar to how TTCs 79 and 8000s are noisewise from the inside. 

But returning back to Novas, I think this noise issue is consistent and related with the "rear heated bench" feature, which for the record, seems to be standard equipment, not an optional extra.

Yeah I'm sure they have plans how to utilize the real estate... I have a feeling one of the boxes will be used for advertising, and the other for service announcements, like subway delays, detours, or closures. They have to monetize the displays, I can almost guarantee it, or there would be no point in having them over the single line LED signs.

Re advertising- what about the panels on the side? Plenty of space there. The last thing a rider wants to see when trying to make their connection is a pizza ad.

 So much has been revised on these new hybrids, there are fewer similarities than differences. Operating characistics are simply an uploaded laptop file, so no doubt it’s different. Tweaks are likely ongoing too.

The whine is due to (for lack of a better term) an aluminum “turbine” impeller assembly mounted inside the traction generator on the older hybrids to move air through the field windings. Not the greatest design feature, as it introduces road grit (abrasive) and salt spray (conductive) in between the tiny gap between the spinning permanent magnets and the copper field coils. Since they’ve typically charging the batteries at anywhere from 450-600v, it doesn’t take much for the polyester coating on the wire to nick and flash over. Makes an oily, salty mud when the rear main crank seal fails too.

Now that they have their own self contained oil cooling, the combined generator and traction motor assembly is hermetically sealed, so no more fan.

Thanks.

I can't remember if this was asked 9 years ago but why are the MiWay 2010 Orion hybrids sound and accelerate so differently than TTC's 2007-2009s? They are essentially still BAE 1st gen series hybrid only with a EPA2010 engine is it not?.

I was on the 3422 today, on 21 Brimley going to SCT. My initial impressions:

  • Seems a lot louder than a Diesel Nova. I sat in the back seats on purpose, and the engine sound was rough and very boomy inside the bus. I had a quick look at a decibel meter app on my phone and the max was ~105db. Not a scientific measurement by any means but it did appear significantly louder. I took a ride back to Kennedy on a Orion NG Hybrid and it was a LOT quieter and engine sound was smoother.
  • The auto engine shutoff seems to kick in at some stops and not others, and doesn't seem to shut off when a bus is at the lights and does not open its doors, or just stops in traffic for a longer period. Seems to be a delay when the doors close to when the bus moves off.
  • The seats are nicely improved, especially the back double sets which have a plastic "filler" between the seats so they don't snag backpack and purse straps as I've seen oh-so-many times.
  • USB ports are neat, lots of them everywhere.
  • The large LCD displays are nice, but they are stuffing the same Next Stop, Stop Request, OP #ID and Time on the same line on top, just like if it was a traditional single row LED. Lots of space wasted where those could be displayed. That may change of course as the TTC figures out what to do with all that screen real-estate.

The series hybrid I later found out they used is the BAE HybriDrive Series-E. It usually shuts the engine off when the bus picks up customers or on a layover. This is quite different and comparable to the original HybriDrive on the 2006-09 Orions which keeps the ISB engines running.

Not like we have a choice in many places. Including video signage on subway platforms. As long as there is no audio on the bus screen ads, it can easily be ignored. The TTC needs revenue wherever they can get it.

Nope. 2nd gen. so what I posted applies to them also. From way I understand, they were one of the first to recieve them.

So basically you guys already have a system close by where you can see the long term reliability (they've been using it for almost 9 years) of this 2nd gen hybrid system instead of being the guinea pigs like the 1st gens where you guys found problems out yourselves.

In a broad sense, yes.

So, explain to me, how is the disposition of a large chunk of the TTC's Orion 7 fleet unrelated to the TTC?

Another question: What???!! I've never seen this before. What is it used for? image.thumb.png.277c8a6acf5146cdb06f403eee16632e.png

Also, are there any more D40LFs at Mt. Dennis? What about the lone Orion V?

They are long gone. The D40LF's I would presume are scrapped. As for 9433, it's definitely scrap.

I would also assume it's scrap at this point.

I am guessing that this unit was forgotten about until you brought it up.

TTC activates external cameras today. Footage on buses and streetcars will be kept for 72 hours while footage on Wheel-Trans will be kept for 7 days.

Does anyone know why (according to CPTDB Wiki stats at least) high ridership routes like the 37 and 41 aren't on the 10 Minute Network?  I know the 41 has artics but it still seems a little strange.

because dispatch feels like it.  

its run 116 for all who feel like venturing out in this thing we call Canada

I thought there was something with the signals preventing the TRs from running?

as far as I know the TR's can run on BD just fine. They ran a bunch of them two years ago during the summer heatwaves when the T1 AC's were horribly unreliable.

Correct.  They can and have shifted Toronto Rockets to the Bloor Danforth line as needed no problem.  The second set of O, P, S, and 6 markers that were added a few years ago as the TRs arrived on both lines indicate to train drivers where to do what with those trains since they have differing performance characteristics to the T1s.

It's the reverse situation that's the problem now that ATO/ATC is live in places on the Yonge-University-Spadina line.  Shifting T1s from Bloor-Danforth to cover a problem isn't practical anymore as they'd be confined to a smaller and smaller part of the line as it gets resignalled.  Once ATO/ATC reaches the interchange between Museum and St. George and goes live there, it won't really be possible at all.

Can you explain what that means, if you don't mind? Thanks. :)
