Oct 16, 2022 at 17:06 comment added Paul Paulsen Thanks for the tip. I also came across the train option after some persistent googling around directly before I had to leave. Unfortunately, It didn't fit my schedule at all due to the timing of the trains and so on, otherwise I would have liked to try it! In the end I gave hitchhiking over a shot, but the only ones who stopped in about an hour were Uber drivers trying to take me for payment. Which is what I ultimately did.

In that case all our delays were at the departure (frozen toilets). I personally think that's the best answer; have a (legal) speed reserve. I think Amtrak is doing that since they haven't tightened the schedule after getting 79->90. However having ridden many transcon trains, delays are an almost unsolvable problem. Stuff just happens. Really, America needs national HSR and pay for it by accepting priority freight also. The freight lines are totally saturated.
Oct 16, 2022 at 7:21 comment added Harper - Reinstate Monica @Ángel historically Amtrak ran at track speed, 79 mph most places due to lack of automatic train stop, but PTC fixed that and track speed is now 80 or 90. Once I was on a late Albany-Cleveland train. Tip top track (but no train stop), dead of night on a Sunday, overpowered train rated for 105 mph. The train Could NOT Be Allowed To Block The Mainline. (relief crew would take hours due to blizzard, which also kept people with radar guns away LOL). The crew would die in 7.5 hours and the trip was 9 hours. Well... I awoke near Rochester, that was not 79 lol. Trip took 7 hours.
Oct 16, 2022 at 3:02 comment added Ángel Similarly, the trains will not be traveling at the maximum speed supported by the engine and track. That would mean that on any slightly adverse meteorological condition, which would force it to slow down, the train would end up delayed. The train will have some margin, which can be used (under good conditions) to regain [part of] the time lost. I remember a case when the train really speeded up, managing to arrive to the station just before hitting a delay deadline which would have made them pay an (higher) reimburse to the users. Something really making them interested on arriving on time :)
Oct 16, 2022 at 2:55 comment added Ángel @Harper-ReinstateMonica you raise good points. However, that's still a scheduling problem. If 9 times out of 10 the train from A to F, arrives F late, the arrival time should have been set at a later time, even if sometimes the delay happen on B, others on C and others on E. And the time that you would have already arrived at F on time, well, you will need to wait (a bit). But that's still better than angry users due to the late train (except for those that arrived late to the station, of course!).
Oct 15, 2022 at 20:25 comment added Harper - Reinstate Monica @nobody easy in theory, harder in practice. You can't leave a station early, and people HATE sitting long times at stations for no reason. Pad time that is behind you is like runway that is behind you - useless. Amtrak's latest trick seems to be to slow down the trains, so they meld better with freight and if they're late they can open it up to regain time. On the backup train, pencil it out for the California Zephyr assuming 2-3 consecutive late trains could happen. How many spare trainsets and crews do you need on standby at Denver, Salt Lake and Oakland?
Oct 15, 2022 at 18:24 comment added Nobody "That means delays only accumulate (stack)" That's not really true... If you don't want delays, you put buffer times into your time tables. You have extra trains on stand by that can take over a route if necessary (so when the train from A to B to C is late, then the backup train will depart B on time towards C). It's pretty telling, in some countries, when you are on a train that departs late, there is a good chance you will still arrive on time. In other countries even if the train departs on time you are not likely to arrive on time. Mostly a question of money.
