if VIA will be equipping Corridor trains with ETCS gear, wouldn’t that get some of the expense out of the way for deploying the same tech on their own trackage?

If QConnexiON manages to win the ViaFast tender, making Deutsche Bahn the operator, its likely that ETCS will be deployed in that corridor as well. If Cadence wins then they wouldn't bother as no company in that group has experience with it.

I dont think thats true, notice how alstom is suspiciously missing from the RFP's?
I think theyre waiting to be the designer and builder of the trainsets for the winner. Alstom does signalling too in europe.

Yes but only a small proportion of the total expense of adding a new signalling system. However, if their trains are already ETCS-equipped then that would certainly encourage them to select ETCS if they're looking for a new system, not just to avoid of the cost of maintaining two sets of onboard equipment, but also to reduce training requirements and potentially reduce the number of signal system transitions along the route.

The question is what Via would gain from upgrading to ETCS. Safety (automatic train protection) is the most obvious one, but that doesn't seem to be a pressing priority for Via or TC at the moment, probably because there haven't been many Via train crashes recently. Unlike GO, it's unlikely that Via would have any routes entirely within ETCS territory, so they wouldn't get the cost savings of reducing from two engineers per train to one.

Capacity is not an issue for Via, since even with HFR we'd likey only be looking at a handful of trains per hour.

Speed is a potential advantage, since ETCS offers cab signalling and ATP. I'm not sure what TC's rule is about max speed while depending on line-side signals, but many countries require cab signalling and ATP for speeds over 160 km/h.

Given the above, maybe Via would be interested in ETCS L1 on Via-owned lines, since it gives them the speed and safety improvements while being simpler than L2 and potentially cheaper for installations such as Via where block lengths are quite long.

ETCS L1 only makes sense as an overlay onto existing signalling. For new-build lines, or lines where the existing signalling is at end-of-life, ETCS L2 is cheaper (as it requires less lineside equipment).

Given that a lot of Via's current signalling was built after 2008, I don't imagine there's much equipment at end of life yet, so L1 might still a more economical option for them. Also since they still need to maintain access for CN using lineside signals.

Though if they run fast/frequent enough service that they specifically need to upgrade the signals, then they'd probably also need to rebuild a lot of trackage in which case L2 would be more economical.

I just saw this and looked back but couldn’t find what frequencies would be. Thanks!
 
The choice of the Richmond Hill line is very wise, and speaks to what a major technical challenge the transition to advanced signalling represents. RH is the least complex line with only moderate traffic. Best place to teach a workforce that has never built or maintained or operated this technology.

I'm certainly not a signaling expert so I could be completely wrong on this, but is it also good choice because there are various speed changes with all the curves?

Be a good way to find out how resilient Eurobalises are to flooding, at least.

I'm not knowledgeable about the intended spec, but if speed control is included, then yes a line with many changes in zone speed, and also PSOs, will be a useful challenge for the learning curve.

Curves also impact fixed signal spacing and location, and track speed.....no doubt the RH line has constraints because of how signals had to be placed so that crews have a hope of spotting them before they roll by. Assuming ML is moving to a virtual-block technology, we could well see speed improvements as the curvature ceases to be a visual limitation.

Alstom is about to test ATO on the ETCS system, specifically with the intent of enabling Remote Train Operation. Given the Alstom is a member of ONxpress and they intend to convert Toronto to the an ETCS based system, this news seems relevant to Toronto if only for yard movements during maintenance.

The ARTE project aims to implement automated train operations (ATO) without the need for additional trackside equipment using the European Train Control System (ETCS). This will support the digitalization of the German rail network and ensure a smooth transition to modernized operations. The Landesnahverkehrsgesellschaft Niedersachsen (LNVG) is providing two regional trains for testing as part of the project. With this project, Alstom aims to test autonomous train technologies on real railway lines and demonstrate how this technology can be implemented by retrofitting existing lines.

The remote train operation (RTO) system is also being introduced within the scope of the ARTE project. Thanks to this system, operators will be able to control trains remotely via tablets. While the train is waiting at the depot or at a specific station, remote commands can be given to manage the train. By monitoring the front of the train with live cameras, operators will be able to both control its speed and ensure the safe operation of the train. One of the biggest advantages of this technology is that it allows remote intervention, ensuring that trains remain continuously operational.
