Interesting idea, but I'm not sure it makes financial sense for Amtrak. Perhaps it would on routes where Amtrak has multiple daily trains (corridors, etc.), but on the typical long-distance route, Amtrak runs two trains per day--one in each direction. That's an awful lot of time for that track to be mostly unused, even if the occasional freight train is allowed to use it. Maybe Amtrak loses millions due to freight delays every year, but you can figure each mile of CTC track costs $1 million to build. Doing this to Amtrak's entire system would cost in the neighborhood of $15-20 billion. It'd take a lot of freight delays to make that project worthwhile.I have to wonder if not delaying Amtrak would cost freight railroads millions, though.
A part of me wonders if, for example, in places where there is currently double track and the right of way is wide enough for a third track, if it would make sense for Amtrak to buy part of the width of that right of way sufficient for one track, and Amtrak could build a new track there to high speed standards, and then some arrangement could be worked out for Amtrak to use the freight tracks along that right of way when they need a passing siding, and Amtrak could let the freight railroad borrow its track in return when there was no passenger train occupying it.
Making the signal system work right in that environment might involve some extra challenges, though.
It depends what you mean by "high speed standards." To reach truly high speeds, the route of the track is as much as factor as the track itself. Anything approaching high speeds is going to need to minimize curves, which existing freight trackage may or may not do. AFIK, with regard to the signaling, Amtrak would need to install equipment for positive train control to be allowed above speeds of 79 MPH.A part of me wonders if, for example, in places where there is currently double track and the right of way is wide enough for a third track, if it would make sense for Amtrak to buy part of the width of that right of way sufficient for one track, and Amtrak could build a new track there to high speed standards, and then some arrangement could be worked out for Amtrak to use the freight tracks along that right of way when they need a passing siding, and Amtrak could let the freight railroad borrow its track in return when there was no passenger train occupying it.

It's also questionable whether trains would just experience additional bottlenecks at places where there wasn't enough room for a third track without major expense. I'd imagine the number of such places would be high.
In a utopian world, what I'd love to see is real high speed corridors installed along major routes, with upgrades made to freight tracks on lesser used routes. For example, extending the Boston-Washington corridor to Flordia is occasionally talked about. However, to make this competitive with airline routes, you'd want true high speed service. I'd love to see average speeds of 110-120 MPH (I believe the NEC is about 60-70 MPH average). At such speeds you'd be able to go New York to Orlando in around 9 hours, which I think thousands of people would opt for over the hassle of air travel, especially with the proper onboard amenities. And that's really not even considering everyone would get on and off at intermediate stops.
I think you could see similar New York-Chicago markets also, and a number of other corridors. However, until things dramatically shift in this country, the required billions will never be available. Not to mention the airline industry will spend millions lobbying against the project and trying to kill it in any way possible (consider Southwest and the Texas TGV project in the early 90s).
FRA standards are a result of many things, including the both of the above, but certainly not limited to them either. Then throw in some politics and you get what we have today.Are the current FRA standards mainly as a result of collisions with other trains? I always thought that they were primarily a result of high numbers of grade crossings in this country, which isn't the case in Europe.
I'm not trying to argue with you but there seems to be alot of line on the ATL-WAS portion that has 79MPH running. Even ATL to BHM, where it is quite curvy, there are a few portions where 79MPH is reached. I can only imagine that properly banked and maintained track would provide faster running. Not saying that 90-110 would be the speed limit for the entire line, but I'm sure that it would be possible for some faster running.The ex-Southern main Washington to Atlanta is a good example of this. Once south of about Charlottesville VA very little of the line is straight enough for a long enough distance to allow even the 79 mph track speed, much less anything faster. And Atlanta to Birmingham: The slightly over 4 hours for 165 miles is as good as it is going to get without an almost complete rebuild on new alignment. For the most part the speed limit is 50 mph and under due to curves.
There is a good deal of 79mph between TCL and BHM and then a fair number sections between BHM and ATN and then a few smaller sections between ATN and ATL. I have been at the stations in ATN and TCL and hear the defect detectors come over the scanner announcing the speed being in the upper 70s and occasionally reaching the lower 80s. Unless there are inaccuracies in the speeds reported by those defectors there si a lot more 70-79 track than there used to be, NS has been doing a good bit of upgrading between MEI and ATL, a number of curves have been smoothed out and super elevated (granted not as much as on the NEC), the Crescent is doing very well at keeping schedule in this section, and amazingly well over the whole route. The last time I was on the Crescent the conductor told me that its not uncommon for them to run slightly above 79, the locomotive's speed limiting software has a buffer of up to 82 for a full minute, so an experienced engineer could take advantage of this to regain lost time, he said he's heard of engineers hitting 85+ in straight-aways then bringing it back to less than the 82 buffer limit before the minute elapsed. Apparently if the crew at the terminals forget to set the software correctly for the route that the locomotive is running trains that run in 90mph territory could be stuck in 79mph mode and 79mph territory could be in 90mph mode or the system could be completely off and only provide dead-man alerter monitoring.I'm not trying to argue with you but there seems to be alot of line on the ATL-WAS portion that has 79MPH running.

It's hardly worth it for an engineer to ever bother trying to push the train up to 85 and risk getting scrammed by the computer for a speed violation. First of course, would be the issue of the computer shutting him down and his having to explain why he was speeding. Second, if he got caught by the host RR or the FRA, he could loose his license to drive the train.The last time I was on the Crescent the conductor told me that its not uncommon for them to run slightly above 79, the locomotive's speed limiting software has a buffer of up to 82 for a full minute, so an experienced engineer could take advantage of this to regain lost time, he said he's heard of engineers hitting 85+ in straight-aways then bringing it back to less than the 82 buffer limit before the minute elapsed.
I'm far from an expert on this, but AFAIK only certain locomotives are fitted with the necessary equipment/overlays to permit 90 MPH or greater operation. Since these locomotives, with the three different overlays are limited in number, they are generally only sent out on routes where they can actually run at higher speeds.Apparently if the crew at the terminals forget to set the software correctly for the route that the locomotive is running trains that run in 90mph territory could be stuck in 79mph mode and 79mph territory could be in 90mph mode or the system could be completely off and only provide dead-man alerter monitoring.
All locos out of DC are officially part of the Chicago pool, and those locos are not equiped with ACSES. The ACSES (NEC) equipped locos largely operate on the Downeaster, Adirondack, Maple Leaf, Vermonter, Lake Shore, and the Springfield shuttles.As for the engine computer being set for 90mph operation, are the Crescent Locomotives not based out of WAS? If so, I would think it would be possible to get a NEC locomotive ocassionally, not always, but certainly sometimes.
Oh ok.. gotcha. Are some of the Chicago engines capable of 90, for the Chicago-St. Louis Portion? Not saying they would ever make it on the Crescent though, that would seem quite odd, but just curious.All locos out of DC are officially part of the Chicago pool, and those locos are not equiped with ACSES.

I know that they were working on improving that corridor, but last I had heard the system had failed and money had run out. So I'm not sure that any trains are operating at the speed on that line. I've no idea what has happened to the few locos that had equipment installed for the testing. They may still have that equipment installed, it may have been removed.Oh ok.. gotcha.

Not anymore and not at risk of loosing the license that allows him/her to do their job. And as I pointed out, unless the train is only about 10 to 15 minutes late, the limited speeding that an engineer can do isn't going to bring the train in on time. Sadly as we all well know, for most trains outside the corridor, we're not talking about being 5 to 10 minutes late. We're sadly talking about hours.Wouldn't getting there on time be a matter of pride for the engineer, and perhaps a reason to speed?
It used to be in the old days, but not this day in age. It is not worth the possible days in the street or the loss of the job all together all because of a speeding violation! And it must be noted, that an engineer who speeds who doesn't work by the rules puts MY job in jeapordy if I am on the same crew. And above all, it can be a major safety issue with my crew as well as other train crews operating in the vicinity. Nope, I am sure it still happens on occasion, but with computers, etc, one should not even take the chances. It is not worth the miniscule time to be gained.Wouldn't getting there on time be a matter of pride for the engineer, and perhaps a reason to speed?
The FRA will still care, and it will suspend, if not revoke the license of any engineer caught speeding.Some crew members do hold a lot of pride in being on time so I would say yes, then you have the problem with crews expiring (in this case Amtrak, the Freight RRs and pretty much everybody else involved would care less if the train broke the speed limit if it meant that a train didn't have to be halted in the middle of nowhere.) Also you have to consider the fact that the crews don't get off work until they arrive at the crew change point or they expire.
Well Alan has pretty much summed it up for you.The FRA will still care, and it will suspend, if not revoke the license of any engineer caught speeding.Some crew members do hold a lot of pride in being on time so I would say yes, then you have the problem with crews expiring (in this case Amtrak, the Freight RRs and pretty much everybody else involved would care less if the train broke the speed limit if it meant that a train didn't have to be halted in the middle of nowhere.)
