Does that mean you are withdrawing your assertion dated February 21 of "$30 billion (I presume you mean incremental investment here) for HAL"?

Well, I didn't say heavier rail per se, I said upgrading rail, but nonetheless your point is well taken, and indeed I made that point myself a few posts ago. What I am infering is that the maintenance costs for keeping that rail in optimal condition to support the 35.75 tons per axle cars has skyrocketed in constrast to the maintenance costs of that track if the axle weights were limited to 25 tons. And don't forget that the 35.75 tons per axle cars were plying the network well before most of that rail was upgraded, basically forcing the replacement of nominally good trackage due to the increased wear and tear caused by the 35.75 tons per axle cars. There was still perfectly functional jointed rail in existance all over that had to be upgraded to 136 lb welded rail once the damage caused by the HAL cars became evident. When you add in the shortline and regional rail conumdrum, you can see how the problem has metastasized. And the HAL article in TRAINS basically supports that contention.

As bad as they might want track for heavy cars, the rate of generation of capital is not going to allow the Class 1's or anybody else to put in track any faster than heavy weight cars go into operation. And you may be a tad under on the replacement rates for cars for bulk materials. It is possible that half the fleet consist of such cars and at 10,000 cars per year replacement would span 75 years.

For reference, here's the last three year's data on new car orders and deliveries:

http://www.railwayage.com/B/freightcars.html

Thus, the three year average for new car deliveries has averaged a tad under 50,000 per year. Of those, approximately 1/3 are true heavy haul cars. Historically, rail car deliveries have averaged about 30,000 a year, so although my 10,000 figure for heavy haul cars is apt, but I'll adjust it upward since the trend is heading upward.

So for the sake of number crunching, let's assume that new heavy haul cars will average 20,000 per year. 20,000 x $5000 is $100 million per year. Or lets take a more "heavy" weighted prediction and go with 40,000 heavy haul cars per year. 40,000 x $5000 is $200 million per year. Thus, it would take 5 years to reach a billion $$, and 35 years to reach the $7 billion figure used for the shortline upgrade example. Either way, the annualized cost of new heavy haul cars equiped with three axle trucks is still far less than the annualized cost to upgrade and maintain a nationwide network of track capable of handling the HAL cars.

Now if you can design a car with a 75 year life, get going, because I guarantee that you will sell a bunch and you if you like you can even equip them with 5 axle trucks.

Well, 5 axle trucks might be a stretch, unless we're going to have 500 ton cars in the future!

That said, we're delving into another topic for discusion, namely can today's railcars last longer than the FRA mandated retirement age? Some shortlines still have perfectly functional 220k cars plying the light rails dating back to the mid 1900's. Thus, it is not inconceivable that today's modern freight cars could last into 2075 if they're not abused.

jeaton,

You give a good cost assumption, but remember we're not talking about retrofitting the entire 1.5 million car fleet with three axle trucks, only new orders for heavy haul cars. That limits orders of three axle trucks to coal gons, grain hoppers, etc. not intermodal, large boxcars etc. Since new car orders for heavy haul cars usually amounts to a few thousand per year, the cost would acrue incrementally over decades rather than in the relatively short time period required for network rail upgrade. Assume orders for heavy haul cars is about 5,000 per year, and the three axle trucks cost the extra $5,000 per car, the added annual cost comes to about $25 million per year, and at that rate would take 40 years to approach the $1 billion threshhold. At 10,000 heavy haul cars per year, that's $50 million per year, or 20 years to approach the $1 billion threshhold.

In other words, it would take hundreds of years before the cost of three axle truck orders would come close to the cost of upgrading and maintaining a nationwide rail network to handle 40 tons per axle, even if the shortlines all go belly up.


beaulieu,

I agree that the Class I's have no real interest in the viability of the shortline industry, statements of "our shortline partners" notwithstanding. But even without the shortlines, the cost assumptions I make do suggest a higher cost curve for upgrading and maintaining a HAL rail network rather than upgrading and maintaining a LAL railcar fleet with three axle trucks for heavy haul cars. Again, I wish we had more raw numbers to work with, because I think this debate is paramount to the interests of the railroad community.


Mac,

Since my hypothesis is predicated on the premise that the amount of steel and the cost thereof required for HAL rail and rail components is mega-times greater than the the amount of steel and subsequent manufacturing intricisies of the necessary components for rail-friendly three axle trucks on all future heavy haul railcar orders, the apriori basis favors my null hypothesis. When an apriori basis favors one side (e.g. the null hypothesis), it is up to the proponents of the alternative hypothesis to prove otherwise if there is disagreement with the apriori.

[jeaton]

I will speculate about the numbers. If the US/Canada car fleet is about 1.5 million and the the three axle truck costs $5,000 more than the two axle version, the eventual replacement of the existing fleet with three axle trucks would cost an extra $15 Billion.

My view here is that it is going to take much more than back of the envelope calculations to derive the answer, expecially when none of us on the forum have any real numbers to work with. I will agree that the railroads fell all over themselves getting to the 100 ton 256k car fleet, and they paid a big price for that in rail replacement and track maintenance. That happened because formulas said the cost to net tare ratio dropped more than enough to give both the shippers and the railroads a big chunk of savings.

Even during that transition, I heard folks of some authority say it may have been the wrong thing to do, but these were voices in the wilderness. Once started, no railroad was going to be able to hold out for smaller cars and survive the competitive pressure.

Seems to me that the Trains report is saying that there is much work to be done before there will be any significant move to a 315k car. Maybe it will result in the wide spread use of a three axle truck or maybe the answer is in rail and track structure or maybe even stay with the status quo. However, at this stage of the game an assertion that any one answer is positively the only way to go is just forum drivel.

You generally portray yourself as smarter than the entire industry. If you expect anyone to believe that claim, which you are clearly making in this thread, you need to provide the evidence. You have not.

The burden of proof is always on the prosecution.

Let's go back to the topic question for a moment. To paraphrase, the topic starter asked about the cost of upgrading rail, presumably to handle heavier axle loads (although he makes the same fallacious generalization as the "rail professionals" of the need for upgrading rail for heavier cars, when in fact the specificity of rail wear is due to increased axle loads, not necessarily heavier cars which are more affective on track structures such as bridges).

My question to you is this: Don't you think it is more expensive to upgrade the nation's entire rail inventory for HAL cars than it would be to manufacture LAL three axle trucks for all new heavy haul car orders? Because that is the gist of the issue. Our nation is at the brink of losing most of our shortline network simply due to the fact that railroad decision makers have decided to stubbornly bull ahead with HAL to increase load factor, when the technology now exists to commercialize track friendly three axle trucks to accompli***his same goal without the need to overupgrade or alternatively abandon the shortline network.

Yes, I wish I had access to some cost figures for installing three axle trucks on all new heavy haul cars built from here on out, so we would have something to compare to the $7 billion figure touted to upgrade our nation's shortline network for HAL cars (not to mention the untold billions probably needed to upgrade and/or maintain the Class I mainlines for HAL over and above that which would have been needed to maintain a LAL sufficient network). Until and if some other TRAINS contributor can come through with such numbers, logical thought does follow that it would have been less expensive to upgrade to three axle trucks for all new heavy haul car orders rather than having to upgrade the tens of thousands of miles of track across the nation.

Also, even though you'd need 50% more braking equipment on three axle trucks than two axle trucks, the wear on those brakes would be 33% less. More brakes cost more money, but more brakes also spread the wear more evenly. More brakes means more stopping power.

As for radial steering (or some variation thereof), one thing is for sure - whether you have radial two axle trucks or three axle trucks, you would never hear a single flange squealing around curves when such trucks have the radial steering.

And one more thing - having LAL's via three axle trucks for heavy haul cars would also mitigate the effects of flat spots on wheels. 40 tons weighing down on a single axle with a flat spotted wheel will cause much more damage to the rail than 25 tons.

Dave, what makes you think that the Class Is are that concerned about the Shortlines? It's not their problem. If the branchlines and Shortlines can't handle the heavier cars then they will have to make do with the dwindling supply of older cars, or buy their own lighter ones. Or perhaps the Farmers will truck their grain to a shuttle loader located on a mainline.

Well, first of all no one is confusing my opinions with the HAL article, because the HAL article didn't even touch on the spread axle alternative. I'm not sure how you can infer that as my presentation of the article's data.

Speaking of sliding in opinions, your statements that the three axle truck would cost "significantly" more is purely subjective, because we don't have any actual cost comparison numbers to analyze. Yes, three 25 ton axles would cost more than two 39 ton axles, but not by much, maybe 25% more, because each 25 ton axle presumably costs less than each 39 ton axle. The use of independent suspension would also raise the costs of trucks, but that would apply to two axle trucks that might use independent suspension as well as three axle trucks. The trade-off comes in greater ride quality for the load.

First off don't you consider 25% more significant? The cost of the truck is more a factor of the cost of the forging, casting and machining required than the cost of the steel. I would expect that the amount of steel used in a two axle truck and a three axle truck designed to carry the same load to only be a little more. The cost of the manufacturing processes to create the parts will be 50 percent greater with the three axle truck. You are also going to need 50 percent more brake shoes, the brake rigging will be much more complicated and if the truck is a radial design the brake rigging will have to be worked around that equipment.

QUOTE:
And you should also point out that the 125 ton truck is much heavier than the 70 ton truck and therefore also increases the light weight of the car, yet because it allows for larger revenue lading it increases the load factor. That same line of reason also would apply to the three axle truck, e.g. the greater the accumulated gross weight limit the greater the increase in lading potential.

I don't understand the relevance of this to the discussion, you are suggesting reducing axle load not changing capacity. I don't think that you are suggesting that your notional three axle truck would be lighter than a two axle truck of the same capacity.

QUOTE:
And I am suprised you include the "increase in rail and flange wear" argument (due to the longer wheelbase of a three axle truck) in the same sentence as the reference to the radial steering, because it is precisely the radial steering that would reduce rail and flange wear, and in fact would make a three axle truck less wearsome to the rail and flanges than a standard three piece two axle truck. Therefore, if the truck has radial steering, the length of the wheelbase is meaningless in regard to rail and flange wear. It may even be that the savings in rail and flange wear from using radial steering would offset the maintenance costs of radial steering technologies.

You may have noticed that EMD has introduced a new design truck for their locomotives, the HTSC a non-radial design. There is some concern that the HTCR radial truck hunts more than the older HTC trucks at higher speeds, not in the pivoting sense, but rather radially. You may also have noticed that the new HTCR - II truck used under the SD70ACes has a heavy strut and damper to control this. If this same effect is seen on radial freight car trucks then it will ad further complexity to control ride quality.

QUOTE:
And we well soon start to see radial steering mechanisms used on two axle trucks. The RailRunner technology already employs radial steering on it's two axle trucks.

The bottom line is that a three axle truck at 25 tons per axle would allow for lighter (and thus less expensive) rail and rail components than the proposed 39 ton axle. HAL is for the birds.

So you say, the power companies and other car owners may say differently.

Start with TRAINS March 2006 issue, the HAL article. Then use a comparative check of the load factor numbers provided by the author with a similar hypothesis plugging in the six axle concept. You can plug and play any number of hypothetical combinations.

Try this one for size. According to the article, the 4 axle 286k car increases lading by "10 to 15 percent" over the 4 axle 263k car, while "weight on the rail grows by only 8.75 percent". Although not specifically mentioned in the article, the 286k has roughly 35 tons on each axle while the 263k has roughly 33 tons on each axle, and they are using 36" and 33" wheels respectively.

With a six axle 300k car using 28" wheels and 25 tons per axle, you get the same "10 to 15 percent" lading increase over the 263k car, but actual weight on the rail decreases by 33 percent!

The article also states that shortlines and regionals represent 30% of the rail network, and would need $7 billion to upgrade their tracks for the 35 -39 ton axles. From that you can infer that it has cost the other 70% of the rail network roughly $24 billion to upgrade their tracks for the 35 - 39 ton axles.

$30+ billion total, soley for HAL! I can bet you it wouldn't cost a fraction of that if they had instead gone spread axle on their new higher lading freight car purchases/leases.

I like the way that you slide in your own opinions as though they were part of the article Dave. The three axle truck you suggest using, would cost significantly more than a larger two axle truck, would be heavier (increasing the empty weight of the car), would have a longer wheelbase even with the smaller wheels (increasing flange and rail wear) or if a radial design would require more maintenance and be much more expensive.

Has any manufacturer, beyond Buckeye Steel Castings ever produced 3 axle trucks in any appreciable quantities? I have only seen them used on loco tenders and some heavy weight flat cars [ mostly DOD] for hauling tanks. I would think that to produce them would have to be an off shore operation, in light of govt regs nowdays.

I see what you're saying Dave, but I'm not sure I agree with your mathmatecal inference. To relate $7billion to upgrade 30% of the rail network as meaning the other 70% will take $24billion, is to say that the 70% of trackage is in the same condition as the 30%. I hope to believe that UP's transcon is in a little better shape than The Ellis & Eastern, which hauls gravel through my town. That little detail could sku the mathmatics a little.[:)]

Well, it is an assumption since I don't have access to individual railroad upgrade cost accounting, but for the purpose of example it is apt. I would venture the Class I's have spent much more than $24 billion upgrading* (or replacing) their lines to 35 tons per axle, then in anticipation of 39 tons per axle, so for the time being I'll stick with the $24 B figure.

*I will concede also that much of the Class I rail trackage had heavy rail in place for those monstrous steamers of yore, and have kept that grade of rail in place when replacing rail. But wouldn't it have made sense for the railroads to keep axle weights at 25 tons and thus at the onset of dieselization been able to go with lighter rail than what was required for the steamers? 136 lb rail does cost more than 115 lb rail, doesn't it? Perhaps if they'd of gone with lighter rail for diesel powered trains, the Brown study could have reflected this cost/benefit in favor of diesels![;)]

I can't figure out why the 6 wheel truck hasn't been perfected to the point at which it becomes viable in this context.

From what I've read so far (and I have a lot of material to go through yet), the older three axle trucks used for the Rail Whales and heavy haul flats had a either rigid side frame (bolster?) or a hinged side frame, but neither was adaquate for allowing the wheels to follow the curvature of the track. The TA2000 from ABC-NACO based on the Unitruck design (with it's independent suspension and radial steering, similar to the Flex Coil trucks used on locomotives) had just come out in the late 90's and hadn't been implemented for use in heavy haul cars, probably because by that time the decision to go HAL had already been committed to, and then ABC-NACO goes belly up and the patents and such are probably stuck in some drawer somewhere. The bottom line is that we don't have any data on the use of the TA2000 radial assisted three axle trucks for use in heavy haul service such as coal and grain hoppers.

When I was riding the Adirondack last fall, the crew was discussing the rehab of the track between Saranac and Tupper. IIRC, they cited $1M a mile. Based on the the numbers given above, that would seem to be reasonable.

[mudchicken]

That $2 Million cost includes signal, structures, more like 30-50 feet minimum in new dirtwork, drainage work, sand fences, structures rehab and so -on. Plus some of the most bizzarre environmental accomodation measures ever seen (404B permitting is out of control)...

That 30 mil a mile comes from what it is costing the BNSF to double track the transcon.

It's only costing UP $2 million a mile to double track the sunset route.... (and granted I don't have alot of industry insight but that sounds like alot of money for a 15foot wide 1 mile long stretch)

Cost reduction!?!?! If cost reduction was a high priority, we wouldn't even be discussing HAL. HAL raises costs, both in terms of needing costlier rail and rail components, and in terms of increased maintenance. I made the point before that should be obviously to everyone - it would have been less costly to make the upgrades to tri-axle bogies than it is to make the upgrades to the rails, because the rails cover what 50 - 60,000 miles worth of material (and how many tons worth of steel?), while all the new railcars, whether the new "improved" HAL railcars or the proposed tri-axle bogey cars, put end to end might amount to a few hundred miles of material at most.

Nope, if cost reduction was paramount, it would have been better to spend "new" money on the spread axle concept for all new heavy load railcars than it is to spend it on replacing miles and miles of track (not to mention the loss of shortline and branchline business due to these incomprehensible HAL's).

Probably more, given the independent suspension and radial steering. The point is, would it have cost more than a new 125 ton truck (both absolutely, and in relation to load factor and rail/wheel interaction costs)?
