GO Transit Fleet Equipment and other

[smallspy]

Hawker Siddeley (the original manufacturer for these cars) originally designed them to be very modular, the Series 1 cars when they were first built had provisions for EMU conversion inside of them, however I assume after multiple rebuilds those provisions no longer exist or would work with modern tech.

GO studied converting the Bi-Levels into EMU’s in a 1980 study and concluded that it would be too complicated and wouldn’t work with a lack of space in the cars for EMU equipment.

This is a bit of a misnomer. Yes, Hawker Siddeley designed an EMU based on the BiLevel (although with some design differences to fit all of the additional equipment necessary to make them so). But the BiLevel coaches as built for GO were not designed to be converted to EMUs.

My understanding of the GO studies was not that the cars were to be retrofitted/rebuilt into EMUs, but more something akin to what NJT is doing, and coupling existing unpowered coaches with newly constructed power cars.

honestly i think this would be a much better use for the bi levels than tacking on locos. they can kill 2 birds with 1 stone, electrified multiple units.

I’m just reading that off the 1978 brochure I have for the GO Bi-Levels (specifically the last two points, or most importantly last point), maybe I’m not getting it right though:

I would interpret that as indicating that as of 1978 the design had the capability to be built with power modules and/or pantograph.

That does not necessarily mean that the cars as built for GO retained the capability to be converted to such. Nor that this could be done cheaply without more significant modification.

Also, being a document dating from the 1978 design - it does not establish that later versions of the cars could be either built with such or converted to such. Subsequent modifications to the design may have traded off some of that potential.

And, since nobody ever took them up on that claim, we have no prototype or even drawings to demonstrate how easy that configuration was (or wasn't) to build. The claim is aspirational, but not service proven.

I did say that in my original post too

My major concern with this bi-level EMU conversation is that it really does seem like the most likely configuration would be set of one power car with two trailers... At which point I question whether there would actually be any meaningful performance gain over a locomotive left.

Most EMUs have unpowered axles, so it’s not the worst issue. You still would have greater adhesion weight.

The upgrade that they should prioritize is fitting all equipment with electro-pneumatic brakes. It would make a big difference in reducing the stop penalty.

The change in paradigm may well be a move away from single discrete cars to two- or three- or even four-car semipermanently connected railcar sets. One sees that happening in many other jurisdictions, including VIA. And when you look at how traction motors and appliances are spread over those railcar sets, you won't necessarily see a "power" car or "trailer".... the car set is closer to an articulated LRV in design, with things spread along the whole set..

That is a plan to go with conversion to Cat5 from the 27pin MU/Com, but how do you figure that it would improve braking, exactly? The trains already have graduated release and blended braking.

EP brakes can be applied and released faster and more evenly than a pneumatic system.

673 I have seen acting as a shunter for Whitby Yard.

If this is GO, I am guessing that means we probably will see more MP54ACs then.

The Boise plant is gone so that would be an interesting situation.

Yeah the B end door and a entire window needed to be removed on the Series 5b-10 coaches to add a lower level washroom, you can’t add them to older coaches without putting them through a massive retrofit.

Here’s a comparison between the Series 1 and 10 coaches, you can see the door is moved over quite a bit on the Series 10 coach:View attachment 584298View attachment 584299

I like these diagrams, thanks for sharing. What's the source on them?

I'm not shocked by GO Locos outside their east side maintenance facility...........but the idea that you, AHK can be found in such a place is astonishing indeed!
