    GO Transit: Construction Projects (Metrolinx, various)

    ^ That might be part of it, but there's no reason why that alone would require such extensive closures/modifications. Given that they say "this work can only be done when trains are not running on certain tracks" makes me think there's some trackwork involved (new switch(es)? crossing...

    GO Transit: Construction Projects (Metrolinx, various)

    Metrolinx's weekly newsletters say that Guildwood is having "signal upgrades" tonight and over the weekend. Does anybody know any specifics? I'm trying to assess whether it's worth going out there for some 'before' photos, and/or hanging around overnight like I did for Waterdown West last month.

    It's not. The tender is still open until August 30th.

    GO Transit: Construction Projects (Metrolinx, various)

    Not as it exists right now: there's only about 4 metres on either side between the edge of the roadway and the points of the switches. So to make room for a detoured crossing, you'd either need to (re)move the switches or build them into the road. This is why the original underpass plans...

    GO Transit: Construction Projects (Metrolinx, various)

    As I write this, CN work crews are commissioning the new controlled location at Waterdown West, which connects the west end of track 4 back to the mainline. This will allow half-hourly service to Hamilton using only a single track between Bayview and Burlington West, keeping GO trains separate...

    GO Transit: Union Station Shed Replacement & Track Upgrades (Zeidler)

    Photography isn't a crime. I'm happy to admit that using the phrase "illegal photo" is hyperbole and/or an oversimplification, but such is life on Twitter. If you think this is a case of "idiot tweets about breaking the law", I promise you I'm not that stupid. It's since been clarified to...

    GO Transit Fleet Equipment and other

    Alstom is not leading the procurement: Metrolinx is. Alstom has no problem maintaining locomotives from EMD and MPI on GO's behalf. In fact, Alstom also maintains fleets of Siemens trains in Bulgaria and the UK.

    GO Transit: Service thread (including extensions)

    Air Canada offered to put me on a Toronto -> Ottawa train (after I'd already volunteered to be bumped twice netting myself $800 cash). I happily agreed. I went to the customer service area in T1 (near domestic security) where they changed my reservation and gave me a prepaid UP Express voucher...

    New GO Train Control+Signalling (PTC, CBTC, ETC) -- Safety & Subway-Like Frequency

    It's a big risk for sure, but not in the way you might think. There's no reason why CN's operations on GO's network need to change at all from how they are today. Given that ETCS's singular underlying design goal was interoperability, the system (writ large) is flexible enough to accommodate a...

    New GO Train Control+Signalling (PTC, CBTC, ETC) -- Safety & Subway-Like Frequency

    I wouldn't say it "doesn't support"; rather, it "doesn't need". A train can operate in L3 on a line that is equipped with wayside signals and conventional train detection, but neither will be relevant to the operation of the train. You're correct in saying that every train needs a train...

    General railway discussions

    The Digital Automatic Coupling (DAC) programme in the EU is seeking to replace the ubiquitous chain-and-buffers coupler on freight wagons with an automatic coupler that includes air and data. They're going to do this on half a million freight wagons and locomotives in Europe. I got a really good...

    That's exactly what the Wabtec FLXdrive does.

    Metrolinx: Other Items (catch all)

    I hope one of the rail people here knows the answer to this question that's been puzzling me for a few weeks. In a recent ad, PNR Railworks were listing the types of assets that they maintain on Metrolinx's behalf. The list included a single WILD (wheel impact load detector). This was a...

    GO Transit: Construction Projects (Metrolinx, various)

    At the Planning & Development Council Meeting on Feb 15th (quite a while before this news broke), Mayor of Oakville Rob Burton asked the Clerk to prepare for exactly this outcome. I can't upload it to the forum so I'll transcribe it (emphasis mine): I guess he had an inkling where things were...

    Union Station platform renumbering and signage

    Nor does their explanation/formula make sense: Except there is a Platform 3. But it's okay, maybe they'll explain it in the next paragraph: Makes sense, follows the formula... Uh... why did the formula suddenly change from 2x(track)-1 to 2x(track+1)-1? Surely it would be easier to just...

    GO Transit: Construction Projects (Metrolinx, various)

    It's certainly the case for the western approach to Waterdown, as the eastbound signal on T3 will need to be changed to protect the new switch. I'd imagine it will change to a three-head signal so it can show (slow/diverging) to limited in case an eastbound movement is routed straight through...

    GO Transit: Construction Projects (Metrolinx, various)

    Thanks for that information. Since we're on the topic, according to the GO Transit Track Standard Plans, the maximum recommended speeds through turnouts is the following (where L = lateral and E = equilateral): no. 8 L: 15 mph, not to be used outside of yards no. 10 L: 15 mph no. 12 L: 15 mph...

    GO Transit: Construction Projects (Metrolinx, various)

    I didn't want to make too big a deal about it in the tweet, because I don't think it's that big of an issue. At the east end, there's a #20 switch good for 45 mph. But at the west end, it's either a #10 (15 mph) or a #12 (25 mph) purely based on the signalling gantry. (In theory I could've...

    GO Transit Electrification | Metrolinx

    The Vivarail D-stock conversions are super neat for many reasons. They've actually got (at least) three types of prototypes right now: straight diesel, diesel-battery, and straight battery. The cool thing about the power modules is they're entirely self-contained. Problems with one diesel...
