2013 Transit Budget

Recommended Posts

Here is the 2013 Budget for OC Transpo: http://ottawa.ca/cs/groups/content/@webottawa/documents/pdf/mdaw/mjg0/~edisp/cap290214.pdf

Take a look at "906964 Hybrid Propulsion Replacement" on PDF Pg 32 of 47 - if I understood the description correctly, it appears that they will select five Orion VII Hybrids and convert it to regular diesel (EPA 2010 compliant) for evaluation.

And here in Gatineau they will increase the fares by 6%. Presumably because of the planned conversion of Express routes in the Gatineau to those local regular fare feeder routes to the Rapibus(unless the opposition is too stiff) rather what they say - increase fuel costs even though they look to be the similar cost at the pumps than last year

cool. I like this... Let Ottawa spend the money, and the TTC will simply observe.

I'd also like to hear what outside entity has designed such a replacement, as they're alluding to.

Both involve cummins powerplants.

I hadn't heard about the "high failure rate" of the electric motors in the hybrids. Nor had I heard about the cracking engine cradles before this report. Other transit authorities have the same model of hybrid bus, do they have these issues also?

The hybrid motors have been failing, didnt hear about engine cradles though.

The engine cradles definitely have, I remember seeing a few at Eastway when I was working there briefly. BTW, terrible place all around. I trusted my work obviously, and a few of the others there, but overall, quality control is really lacking. I doubt the Orion VI's that were refurbed there won't last as long as they promised.

With regards to the Hybrid buses, here is a link to the presentation they made: http://app05.ottawa....gs&fileid=29565

Loved the presentation. Thanks JCL.

I suspect OC Transpo would not be considering de-hybridization if they had routes with more frequent stops. Anyone know how many stops per km on Routes 2, 85, 18 and 14? (referred to in the presentation)

Sorry for not replying sooner.

In regards to your question on how many stops per kilometre, I'm not able to provide you a number, but I can tell you that there are a lot of bus stops placed closely within each other. Also, those bus routes do encounter heavy traffic congestion and a lot of signalized intersections.

As for Route 85, this route requires artics on weekdays and Saturdays because of ridership. Route 12 would also be a good candidate, in my opinion, for hybrids but requires artics.

Late reply, but Toronto's hybrids have been plagued by engine cradle structural cracks too.

Jury is still out as to wether we convert, or just retire them early.

At the current moment, not only are we paying big money for batteries, the cummins engines are failing at a remarkable rate.

Medic, are you talking about buses 1000-1149 (from 2006)?

Is there something about the series hybrid system that is hard on the engines? I recall you noting problems with those ISBs before. And here I thought they were supposed to have it easy, sitting in a sweet spot to feed power to the generator.

Is the engine undersized for the application?

Any news on this proposed hybrid propulsion replacement project?

I have just been going through the audio cast from the past Transit Commission meeting posted on the City's web site (November 20, 2013).

One of the Transit Commssioners did ask management about the progress of this project. Apparently the money budgeted for this project was not spent at all in 2013. According to management, they've been working with NRC to study the whole issue of hybrid buses and whether the conversion should go ahead. OC and NRC are supposedly finalizing the study and put together proposals.

Other than that, there have been no specific details given out on what exactly they are going to do next with this project, other than management saying that they will start spending that budgeted money soon. We will have to see whether they will actually be doing any conversion(s).

ALL of them. Not just the 2006s.

The late production 24 valve 5.9s and early 6.7s have proven themselves to be unreliable in general,

As have most diesels from about 2006-2011, when urea dosing came about.

Any updates on the hybrid buses. how long will they be evaluated for?

I personally haven't heard anything new on this project other than what I wrote a few months back.
