blue streak 1Here is a thought. How many classification yards are there in North America that receives cars from other yards (n)? If a major RR yard had (n) classification tracks then each track would be able to have blocks that would only be subject to block swaping to final yard. Of course various tracks for RIP, Storage, trim, departure, etc would be needed. No additional classification of car(s) until reaching final yard. Not too practicl. Even with another set of yard tracks maybe a mile beyond the first yard set way too many switches and other infrastructure?

In the final years I was working, the 'plan' was to eliminate switching at as many outlying points as possible, thus eliminating yard jobs at those points. Put EVERYTHING from the outlying location together for pick up by a road train to take it to a hump yard to separate everyting towards its ultimate destination. That plan could put several hundred additional miles of backhaul for some traffic.
I never got to see the 'savings' sheet with what was save from crew abolishments and what additional costs were incured in car hire for both the additional day(s) cars were on the property plus the additional milege money the accrued in the car hire accounts.
Never too old to have a happy childhood!
SD70Dude I've got to say that I'm a bit disappointed. I was expecting something more creative, perhaps a giant 'hand of God' in the sky. You know, the fastest way to switch on a HO scale layout.........

In the beginning of railroads, it was natural to perform switching just by using the basic train hauling principle of flanged-wheel railcars running on tracks as though they were short trains with very short destinations. But with advancements of machinery, automation, and computerization, maybe the railroads can move beyond the mechanical speed limits of current yard switching practice.

Our Symington (Winnipeg) and MacMillan (Toronto) hump yards are both duals. And they survived Hunter Harrison's rampage up here. Must be pretty efficient.

EuclidHigh capacity multiple-stage railway switching yard It looks like there is plenty of development under way to make railroad switching yards more efficient. Here is a Patent reference with a lot of detail, but a little hard to follow. What is needed is highly detailed animation that shows what is happening with all the moves; accompanied by clearly explained narration at each step. This type of explanation should also show how this new system differs from the current state of the art. https://patents.google.com/patent/WO2002042142A1/en
zugmannI worked in yards that have that. Not exactly a new invention. Quite the opposite, actually. A lot of older yards have multiple crossovers, or switching leads in addition to ladders, many of the latter being compound. Could easily have 4 crews working in an area at once.
Yep. The dual hump at the "why, exactly did we build this? Moorman hump yard" in Bellevue OH was supposed to accomodate two trains humping at once with a crossover on the down hill portion of the hump.
Worked great in process simulations. Never worked in practice. Why? Not for any reason I could comprehend or understand. So, there's that.

I would need to see this diagrammed to see where the advantages in the 'multiple movements' are, but I speculate that the 'other railroad context' would be CTC.
The immediate applicability of this is not in 'marshaling trains' but in making up ordered platoons of those Parallel Systems autonomous boxcars. I would dust this idea off and see if there is a 'fit' with some of the things their current paradigm hasn't worked out yet.
The other thing this needs is a well-designed 'autonomous' counterpart in each of the switches. These will have to work many times more frequently than 'regular' yard switches and would be difficult to 'route-interlock' in the ways current complicated track layouts need to do to be safe. What you will have is multiple autonomously-guided movements that will have to have their switches thrown as they go, but coordinated on a larger scale for safety and for dealing with anomalous conditions (power, derailment, weather, etc.)
croteaudd If multiple movements transpire simultaneously what tremendous time productivity could be had

Many yards lost some of that in favor of simpler ladders with larger switches (cars/engines getting longer and heavier), less to maintain, blah blah blah.
croteauddThis likely will be my last post or one of my last posts, as posting and sharing ideas has radically changed in most areas in the last five years, and hostility is everywhere now and misinterpretation is the order of the day. Besides, few seem to be left here at the TRAINS magazine forums. For the civilized posters that remain, best wishes and it is hoped things go well with you!
You keep saying that, yet you keep posting. If you're going to go, just go. Or stay. Nobody really cares.
So that Backshop and others here won’t have convulsions or a possible heart attack and die on us, I attempted to diagram what that attorney was shown close to thirty-five years ago, but because the TRAINS website chronically malfunctioned, I gave up. But picture two parallel tracks with a bunch of X double crossovers. If multiple movements transpire simultaneously what tremendous time productivity could be had!
As noted previously, with Intermodal, railroads are no longer confined to rail access. So, boxcar, tank car movements, and the like I don’t believe has a future. Thus, it is now questionable how practical a ‘sorting facility’ as described above would be, especially as those mentioned shipments decline and the costs of the movements go up dramatically.

I can't see any railroad stampeding to any innovation unless it was something they saw someone else do first. Most militaristic organizations operate this way. Change has to be forced upon them it is rarely a voluntary operation.
croteaudd Over three decades ago the elevator brought me up to the patent attorney’s floor. In his office, it took only a few seconds to draw him a new type of yard. At seeing it for only two or three seconds more, he exclaimed, ‘There is money in this!’ What he didn’t know was that what I drew him already exists in another rail form, so can’t be patented!

Ulrich I'll reserve judgement as I don't know what the idea is.

I'll reserve judgement as I don't know what the idea is. But sometimes the best ideas come from out in left field, from people who aren't familiar with the industry and thus aren't encumbered with "how it's always been done".
Having said that, I wouldn't waste time and money on a patent. Instead get a prototype if you can and market the heck out of it. Patents will make the patent lawyers happy at your expense and that's about it. If your idea is any good it will be copied regardless of any patent..may as well forget about it, or maybe just state "patent pending" which costs nothing and may serve to discourage the laziest of the copycats.
This thread got me thinking about the Electrification thread where many of us regular posters stated how old we were. Most here seem to be enjoying their retirement years, even with the physical challenges. A few though, are turning into bitter, grumpy old men who aren't happy with their life and what they did/didn't do.
croteaudd To round out my perspectives, my vision involved (1) mainline operations, (2) labor peace methods, besides that (3) sorting facility. And, for the record, two man crews are a must, just like two pilots are a most for commercial airlines!

I seriously doubt that the OP could attain labor peace when he's insisting on two-man crews.
croteauddAs exhibited by posts in this thread, railroaders (as in any industry) tend to be hostile towards change and economic reality discussions and prefer to be in a dream world.
Says the person that has never worked in the industry (I'm guessing) but has this "dream idea" of a new yard but it's a secret that won't be discussed?
Go sell your plan and be rich if it's that great of an idea. Stop wasting time playing victim acting like the only impediment of your plan is that "people don't understand".
Our yard can get full of "idle cars". But that's because the customers are full (or closed gate) and aren't taking them. What are we going to do with them? There is literally nowhere else to go with them, unless we send them off the other direction for some kind of S.I.T. sort of thing.
And if our yard gets full, the next bigger yard further up the pipeline may have to hold some of our cars becuase we don't have room, but they do.
Just because a yard is full of cars doesn't mean the RR is doing something wrong. That's a very narrow viewpoint.
croteauddSimply put, that ‘sorting facility’ (NOT a yard, that implies idleness) is so, so stupidly simple.
I know - you could even put gravity to work. Push the cars up a small hill, and when they crest the hill, they can roll into tracks designated for specific destinations. When the track is full, or when a train is scheduled to head to said destinations, they can pull all those cars and take them there!
If they don't want to make such a hill, then locomotives can push the cars into such designated tracks. In fact, if they get a little speed up, the cars will roll to their destined track.
So simple! It's a wonder no one has thought of it.

You, Euclid, seem to be more civilized, and are to be commended for that! Indelibly etched in my memory are photos of railroader’s disillusioned faces when all the famed passenger trains ended and Amtrak took over in 1971! That reality was a hard pill to take for many within railroading, but reality is reality.

Retirement is blissful and I no longer try to get people’s attention. A fast sorting facility is only presented herein to get railroaders and railfans to think! Can you imagine a whole train sorted in just a few hours and then the cars being on their way instead of cars being in a hump yard for 24 hours or more? We all follow a dying industry! In 30 years, I don’t think there will be boxcar traffic. Nor petroleum tank cars. So, the miracle sorting facility is eternally dead. Intermodal is the next to die as ‘time value of money’ conscious shippers start zeroing in on time. Have fun kicking all this around! (Nothing more will be said, no answering questions, no nothing!)

CN, UP, GATX and TTX have all been taking delivery of brand new plug door boxcars over the past year........
As long as there's someone that thinks "I'd rather get one huge delivery once a week instead of five small deliveries five times a week" or "I need 500 tons of this stuff and I need it all at once," it isn't a dying industry.
??? Dying industry? Last I checked carload handles mostly commodities that don't require expedited transit or sorting... I mean we have SIT (Storage In Transit) for a reason..
You also say boxcar traffic is dying? Well considering the change in industrial production to smaller lightweight cube out widgets. What good is a boxcar? Boxcar's have settled into a nice niche handling: forest products, appliances, beverages, and longshelf life perishables.
Concerning your remark on tankcars hauling petroleum.. Not anytime soon. Nor ever... Petroleum outside of product, happens to be the building block comprising alot of your everday items..
"there is money in this" can be read either as "it has potential" or it could mean "I want those five minutes of my life back"
croteauddCan you imagine a whole train sorted in just a few hours and then the cars being on their way instead of cars being in a hump yard for 24 hours or more?
I mean, we do that in my yard like every day. Still don't know what this new yard design is. Does it involve trebuchets?
We just adopted a cat from our local humane society, and so I was looking into some pet food companies to determine which food I want to feed him. Interestingly one company has as part of its mission to increase use of trains rather than trucks for the transportation it uses.
