Not what I said. But sure, if you feel feisty over a disposal method and want to ignore the actual point, go with that.....
Isn't it? Here is the flow of conversation. It started with you saying:
What VIA plans for and what is the depreciation timeframe are two different things though. VIA can plan to use them for 30 years, with the locos having substantially reduced economic values after 15 years. Basically, the point at which they need a midlife overhaul is the best time to try and sell them. Get someone else to pay for the overhaul and a good time for VIA to buy the latest and greatest.
To which I asked the question:
Who would VIA sell them to? If the conditions have changed such that VIA needs to replace them with some type of fully electric locomotive, I don't know how much market there will be for used diesel-electric locomotives. Even if there is a market, they would be getting pennies on the dollar.
You quoted the part in bold and replied with:
Mostly because they might not need them if funding comes through for BEMUs.
Again, we're all looking at all these discussions through the lens of VIA as they are today. But the Charger/Venture fleet won't be fully delivered till 2024 (2025-2026 for VIA). So 15 years from that is the late 2030s. That is a long ways away. In that time, assuming HFR is built and hopefully even extended, VIA will be a substantially different entity. GO will have hopefully finished the RER buildout and may even be considering service and electrification partly or fully on the HFR corridor to Peterborough. Battery tech may be so good that BEMUs capable of doing 300 km at 200 kph will be available. At that point, it becomes logical for VIA to consider whether a midlife update makes sense or they would be better off selling the whole Charger/Venture fleet to some developing country and get a brand new BEMU fleet, or even just sell the locos and get an electric tractor (like the ACS-64). We'll also have a much higher carbon tax at that point, improving the business case for moving away from diesel substantially.
Most of that reply (other than the part in bold) has nothing to do with the question you were supposedly trying to answer ("Who would VIA sell them to?" or in other words, who would buy them). The rest is trying to justify why the new fleet would become useless (which I had kind of said, though only about the Chargers) but you chose to ignore (and delete) that part of my post.
The point is, if battery technology improves so much and carbon taxes become so great that the entire new fleet (not just the locomotives) are obsolete and useless to VIA Rail and need to be sold, the same would be true for any potential customer of the new fleet, unless they were looking for a bargain and didn't care about carbon emissions.
Implicit in your post is the assumption that coaches can't be easily reconfigured at depot. And that they must be sidelined if they don't fit a consist configuration on a PowerPoint slide. I don't think that's how things work in the real world. The coaches are configurable.
I'm not 100% sure what you mean by "reconfigured." I agree they can build trainsets in configurations that are different from the ones listed in the PowerPoint slide. There are likely reasons they chose the configurations they listed.
However, If you are trying to say that they can easily reconfigure business class coach with approximately 44 seat into an economy coach with approximately 66 seats, I disagree. I expect the business class seats are wider to allow passengers to be spaced further apart, so they would need to remove all of the seats and replace them with economy seats. Not a type of reconfiguration that can be quickly and easily done in the depot. It could be done in a refurbishment phase, but I don't expect that to happen for 15 years. It would be better to have the correct number of each type of coach built that they expect they will need.
They might be able to use a business class coach as some type of economy plus coach (the seating configuration of business class without the service) but given that economy class on trains is much more comfortable than economy class on airplanes, I don't know how much demand there would be for that type of service, especially if only a few trains had it.
And should be particularly easy between subtypes in the same category. (Economy 1B to 4A).
I totally disagree with you that it would be easy to convert a cab car (Economy 4A) into an extra economy car on a train (or vise versa). The cab cars will likely have a standard (Janney variant) coupler at one end of the coach and a semi-permanent coupler at the other, so unless you coupled 2 cab cars together nose to nose, you can't insert them into the middle of the train.
Not that they would. But if demand warranted it, they absolutely should. That's how economics works. Acela in the US is an example of this. All business class service.
That would only be feasible once we have HSR in parallel with HFR. The HSR trains would be a premium product and the HFT trains would be more economical. This is not something that we should be planning for before we even have HFR.
