More importantly if the siding is not long enough to hold the long freight train then it is the short Amtrak train that goes in the hole while the long freight train trundles by slowly or even at a moderate speed.
I thought the Amtrak train is always the one that the host railroad puts into the siding.
No. That is not true at all. Though it is true that when an Amtrak train gets placed in the siding, the uninitiated notice it, whereas when it thunders by freight trains parked in the siding very few notice it. The latter is the more common occurrence. Otherwise Amtrak trains would consistently be days late.
Nope. I think you're more into wishful thinking, than basing such on any kind of facts.
From my years of travel on Amtrak, I find that its the Amtrak train that gets the siding more often than not. I don't know if such is a matter of the host railroad keeping its own trains moving, and on time, vs. a train that just a mere guest. Or if its the reality that the short Amtrak train can fit into the siding easier than the typically quite long freight train. Or if its that the short Amtrak train can slow down, and even stop, easier than the heavy freight train.
Plus, its the freight train that thunders by, not because of speed, but rather its enormous weight on far more wheels.
Actually, you're the one that's not basing this on any sort of facts (and the semantic argument over whether any given train "thunders" by another doesn't really help your position at all).
That your experience comes from years of
traveling on Amtrak rather than from the front seat of a locomotive or a dispatcher's desk, where your view is limited to what you might be able to notice outside the window, if you happen to be looking (and only while awake) actually is what jis was talking about. It's a lot more likely for a passenger to notice the train they're riding slowing down/stopping than the train they're not riding. Some of it is a matter of you actually being able to feel what is happening to the speed of your own train. Some of it is just a matter of visual illusion (when you're traveling at 50/60 mph, it's hard to tell if something next to you right out the window is stationary, or moving slowly in one direction or the other). And some of it, as I said, is a matter of the passenger simply not looking out the window 100% of the time to see when you pass other trains.
The statement that Amtrak gets the siding "more often than not" is simply a false statement. If you have data that show otherwise, let's see it.
As for another common theme on this thread, I find the siding length argument to be rather irrelevant. There are some situations on Amtrak routes where some freight trains can't fit in the siding, but in general, that's not that big of a factor. After all, Amtrak is passing a given siding a couple times per day, whereas freight trains on these lines may be passing that same siding a dozen or two (or more) times per day. If a railroad's freight trains couldn't fit in their own sidings, then in many cases they wouldn't be able to run anything, since (and again, a passenger would almost never see this) a freight train meets another freight train far more often than it meets passenger trains. This is obvious given the sheer difference in the number of freight and passenger trains.
Now, to get really nit-picky about the topic, not every train that waits for another does so on a siding. Plenty of trains hold the main track waiting for the other train. There are plenty more examples of trains in multi-track territory waiting for other trains, for any number of reasons. Often the question of who has to wait is simply decided by who gets there first. Now, the dispatcher could hold a freight train further back so that it's tucked away by the time he passenger train gets there, but that could actually tie up the railroad even more (particularly when there are other trains behind it).
Main point being, it's generally not possible for a passenger on the train to get the lay of the land as far as what's happening around him/her on the railroad.
