Honest question, are the covid vaccine 7900 buses returning to service?

They maybe rolling stock, but I wouldn’t officially know for sure. 7958 passed by Mt Dennis after dropping off 7937 a few days ago

Hey @Bus_Medic @FabianColeyLOVESBUSES, can anyone tell me the fate of #1220, #1255, #1288, #1318, #1352, #1576? I think they’re likely being decommissioned despite being tracked dead on the same spots.

1288 has a rear axle spindle that pulled out. Most logical fix is a complete axle swap with another decommissioned unit, they’re on the fence about investing the labour.

I’ve  been off since the end of august burning off my vacation now that a pending surgery date has been set. My modified duties assignment during my rehab likely won’t be anywhere near Malvern, so I’m not able to update for several months to come.

The others I really don’t know but the usual culprit is a fried traction motor or generator.

No less than six traction motor cores were prepped for shipping to Harvey for rewinding my last day there however, so they may be turned around in the next month or so.

I don't know of this is the right place for this but does anyone have a picture of a ng hev traction motor? I'm curious as to how it looks

I thought I had a picture of one removed from the bus, I guess not. End cover is removed in this one. They’re normally hermetically sealed, oil cooled.

Both the 1000s and the NG orions use the same traction motor, and are completely interchangeable.

does anyone know whay these mean? I see them and other similar phrases on retired buses.

Top: veam (brand name of heavy duty electrical connector) are physically  disconnected on the roof.

Translation: the battery tub has been electrically isolated  from the rest of the bus, rendering all high voltage components downstream safe for removal or decommissioning.

One task on a checklist of about 25 things that must be done before a bus is released for scrap disposal.

 

Bottom: Propulsion control system (PCS- the 2nd box on the roof at the rear) has been removed, either for repair or re use elsewhere, and the high Voltage side of the bus must not (and frankly can’t be anyway) energized. Actually, the vehicle data loop runs through there, so the multiplex won’t work, and nothing will run.

Usually with decommissioned buses, there’s a shopping list of major parts to pull off to be cannibalized, PCS, ACTG (alternating current traction generator) and/or ACTM (alternating current traction motor), depending on what failed in the first place to bring about it’s retirement. The tape notes just save the next shift a few minutes time knowing what’s already been completed at a glance.

Ah understood. Decommissioning seems more complicated then pulling off parts and decals lol

Does anyone have any updates on 1202? It’s been sitting around at Mount Dennis for nearly a month now. It’s either getting new plates, waiting for MTO inspection, waiting for a part or possibly retired. The traction motor sounded pretty awful the last time I heard it.

I am curious about the life span for these parts,how often do they change them?

It's not a rumour. I posted a few weeks ago that 1120 was retired. You must have read the post since you reacted to it. Why ask again?

Yes I know it's retired. I was simply wondering if the collision information was true or not as you never mentioned it. If it's true then what exactly happened?

1120 was in a collision and the damage was deemed too expensive to fix. As for what happened, we are not told the details of collision investigations so I can't answer that part of your question.

Dam, I was hoping none of the 10/11s would retire from fires or collisions, there goes that

Given how badly people drive in the GTA, collision happens all the time. As the fleet ages closer to retirement, they will be deem not worth the repair cost. So it's bound to happen to all batches.
