Question, Dan, would a regulation tying freight train length to siding length be likely to produce a useful outcome?
ie. If CN/CP were told, you can run a train only as long as the length that sidings along its route can fully accommodate, thus allowing either the freight or a passenger train the ability to pass/be passed.
It has happened in the past on a number of occasions - CN has had Transport Canada issue orders limiting their train lengths on a number of subdivisions over the years for various operational reasons, but they are generally for a short term and as a punishment for deeds done (or not done, as it were).
But to enact a piece of regulation to do so on a permanent basis? I really can't see that happening. Transport Canada is basically a lobby group for the freight railways, and any move to limit train lengths on an ongoing basis would only serve as a detriment to the freight railways' operations.
To continue with your hypothetical situation, however.....I'm not sure that it would be particularly useful, to be honest. It would require more crews to move the same amount of traffic across the railroad. It wouldn't necessarily make those trains travel any faster either, as the freight railroads run their calculations and therefore operations based on a trailing tonnes-per-horsepower rating for each train, and therefore each train would have fewer locomotives. While the trains would then be able to fit into more sidings across the railroad, without other plant improvements those trains are still entering and exiting the sidings at low speed.
No, I think what is far more beneficial for everyone involved is more track and switches, along with localized improvements in alignment where possible and desired, and improvements in the signalling system to allow for both higher speeds (especially into the sidings that can handle just about all of the trains as they are) and shorter headways between trains. But unfortunately, those things cost money - something that the freight railroads are adverse to until it's almost too late.
I can answer that... yes. The main reason VIA goes into the siding is the trains they meet do not fit.
That's extremely simplistic, and not necessary true. When meeting trains, it is generally preferred to put the first train arriving at the meeting point into the siding to allow the second train a more preferential signal indication - and thus allowing it move out of way more quickly.
In that case, it's irrelevant whether the train is a passenger train or not. It just matters to keep the railway fluid.
