Absolute Dollars perhaps? The ratio was improving, but the worst performing trains were being cut off and it wasn't helping much. Overall the railroads financial performance was sinking. Do you have the figures for AT&SF? They were still trying to run top quality passenger trains on their most important routes.

There are two fundamentally different methods of financing involved here...................................


That's great but how about answering his question??? I've noticed you conveniently ignore relevent questions or go off on tangents hoping to confuse readers. Fortunately most of us are too educated and intelligent to fall for it.

Well, just because you didn't understand the answer, that's not a basis to assume I'm "hoping" anything.

Steam $120,000. Equivalent diesel, $160,000, financed. Steam paid out of internally generated funds. It costs $120,000. Diesel, financed at 5%, costs $207,207 dollars, at 10% $260,392.63. Ultimately, that is three times the cost of the steam, because the funds are borrowed, not internal.

Answered?

I appreciate that you feel both educated and intelligent and look forward to that approach to the conversation.

Best regards, Michael Sol



If they had internal resources of $120K for Steam they only need to finance $40K to upgrade to Diesel. Apples to oranges me thinks??[?] There cost analyisis showed the savings of increase transisit time with additional reductions in labor and facility charges should have offset the finance charges. The dramatic drop in passenger revenues and steel wheel to rubber did not allow this to happen. Bad crystall ball not bad cost forcasting. It was there own consevative inability to adapt quickly to changing traffic cycles that drug them down. Not EMD's sales department.

How about providing some reference for your views, for starters? All you've done so far is to attack a logical premise and hard statistical data with nothing but your Democrat spitballs. You and Hillary make a nice couple.

If you have a reference to your inference that the 1940's - 1950's dieselization improved the railroads ROI rather than degraded it, then by all means present it here in this thread. We won't even accuse you of trying to "hijack" this thread back to status quo of possible mythology as it relates to the *history* of dieselization into which we've all been indoctrinated.

You seen to believe in some sort of conspiracy to undermine the credibility of the railroad press. What's it to you, anyway? Does it really harm you or your trade if it turns out that the method used by the industry to dieselize may not have been the best way to accompli***his task? Isn't the whole purpose of historical analysis meant to get it right, rather than allow myth to become percieved as reality? Most of us know that history isn't black and white, that there may be certain misconceptions that have been worked into the fabric of establishment, and to re-explore these possible misconceptions so that the factual record is not scewed, such is apt.

Besides, we all know that the established railroad press is rife with gross misrepresentations of fact. Take the rail industry myth of highways being "subsidized" while railroads are entirely financed via the private sector - we all know that intercity highway corridors are all paid for mostly via user fees, it is only local roads that get de facto "subsidies", and of course the rail industry is immersed in various amounts of state and federal aid over the years. Or take the AAR's propaganda campaign that railroads are "taking trucks off our nation's roads and highways", when in fact the whole process of retrenchment of trackage and consolidation of rail terminals has actually forced more trucks onto the highways. Or the false premise that longhauls are more profitable than shorthauls, when actual cycle times relative to per car rates more often than not prove the opposite to be true.

Nevermind, Old Timer, you go right on believing whatever the railroad press has established as *fact* over the years. 1940's Dieselization good, 10 year old steam bad. Longhaul good, shorthaul bad. Highways subsidized, railroads not. Trains take trucks off highways, not put more trucks on highways.

There, now do you feel better?

If passenger expenses were "exploding," then the only thing that explains improving operating ratios would be that revenues were "exploding" even more.

I doubt that.

Railroad ROI during this period was declining. Passenger service had nothing to do with that. Rather, improvements in passenger service operating ratios could only benefit ROI during the period of Dieselization, at least for the railroads referenced.

To Anthony's comments.

I've gone back and revised some of the numbers to show correlations with ton miles, removing the Electrification numbers entirely from the mix. Except for percentages, all numbers are stated in 1944 dollars. Further, train crew and train "enginemen" expenses were looked at. No yard crew or expenses are included in these figures.

Cost per 1000 ton miles, locomotive fleet maintenance, plus fuel, plus financing charges.

1945: $1.24/1000 ton miles.
1960: $1.54/1000 ton miles.

This is a 25% increase in costs during a time when revenue declined by 17.5% and all other operating expenses declined by 23%.

Interestingly road crew costs increased as a result of Dieselization. Comments on this thread would have led one to believe otherwise. The 1945 cost associated with road service train crews was 89 cents per 1000 ton-miles, and after Dieselization was completed had increased to 96 cents per 1000 ton-miles, a 12% increase in road crew costs.

During this period of time, wages associated with maintenance of way decreased by 41% and wages associated with station agents declined 43%.

Overall, fuel, maintenance, financing, and road crew costs, which represented 18.5% of revenue in 1945 consumed 23.3% of revenue in 1960. Overall, these expenses increased by 21% from $2.13 in 1945 per 1000 tons to $2.59 per 1000 tons in 1960.

For this specific railroad, fuel costs and maintenance costs declined, but these savings were overwhelmed by financing costs and crew cost increases.

Not exactly the conventional wisdom, and the analysis is far from complete, but I think these numbers leave no doubt that the idea that Dieselization was an economic benefit to this particular company is just simply false. There is no basis in the statistical record for that conclusion. Since this supports H. F. Brown's findings with regard to the Santa Fe, the Pennsylvania and other U..S. railroads he looked at, Milwaukee Road at least is further evidence supporting his findings, that Dieselization "represented a net economic burden on American railways."

With that, I've analyzed these numbers just about every which way and they keep leading to the same result. There is no doubt to me that anything which increases operating costs is going to decrease ROI, particularly when the substantial investment made generates a net negative internal rate of return.

While the admiration for Dieselization takes on virtually religious overtones -- in which no factual demonstration to the contrary will shake an article purely of faith -- railroads are business enterprises. There is no place for pervasive mythologies perpetuated by self-annointed knowledgeable insiders. As I noted to one of teenagers early in this thread: "go to the source."

Interesting misfire on facts, since the motivating study on this was paid for by an experienced railroad, British Rail, which practically invented railroading, at the time a government agency, and the study was conducted by the most experienced transportation consulting firm of the era by one of the most experienced motive power engineers of the time.

Talk about false assumptions ....this isn't just a misunderstanding, this is willful ignorance.

Spin, pure and simple.

I don't know Brown personally. But I did know the Boston and Maine and Denver and Rio Grande Western managements personally, and always had huge respect for the Norfolk and Western. The B&M had some special reasons for rapid dieselization, which I discussed ealier on this thread. Indeed, so did the Santa Fe with its getting-water-to -the desert problem. But the hardheaded and competent managers of the D&RGW and N&W also opted for fairly rapid diesilization, the N&W after giving modern steam the very best opportunity to prove itself that any railroad could. I cannot agree that their decisions were wrong.

At the same time, Michael, regarding the Milwaukee, you may have a point, especially since many people agree that the western extension should have been kept as the real moneymaker, and somehow the money should have been found to upgrade and extend the electrification. That certainly would have slowed the conversion of the rest of the system to diesel.

Michael - Thanks for the analysis. You have done a great job making and defending your case. I'll admit that I have nothing to offer in the way of analysis since I have no access to inside railroad data. I can only ask questions.

Have you considered writing an article for Trains Magazine, rebutting Jerry Pinkepank, the author of the article "How the Diesel Changed Railroading" in Diesel Victory? His response would be interesting, since he is supposed to be a renowned international railroad consultant.

What I'm trying to get a handle on is what direct and indirect economic benefits the Diesel offered to the railroads. I'm visualizing a balance sheet showing debits and credits for the Diesel. If I understand was has been discussed thus far, Michael's analysis indicates that there was no economic benefit to the railroad anywhere. (I'm a little confused as to whether the Diesel saved the Milwaukee Road anything in fuel and maintenance.) No credits, just debits. I am searching for anything we can place on the credit side.

Can anyone show quantitatively any economic benefits realized through Dieselization? It should be easy to show if any of the following qualitative advantages are true.

1. Lower terminal costs because locomotive "turning" is reduced/eliminated.

2. Reduced track damage by eliminating the hammering associated with steam.

3. Reduced intermediate servicing facilities.

4. Reduced non-revenue carloads associated with fuel transportation.

5. Easier on-site handling and storage of fuel.

6. Elimination of water towers and the whole issue of boiler water quality and treatment.

7. Elimination of ash handling and disposal.

8. Higher locomotive availability.

9. Reduced need for helpers.

10. Higher efficiency due to a more centralized operation.

Can anybody shed any light on these or any other areas?

If we cannot show quantitatively that the Diesel benefits the railroad anywhere, then what else can we conclude?

As rrandb asked, why would it ever make sense to Dieselize?

Thanks

Anthony V.

Steam has certain advantages. We have plenty of coal resrves which they can use as fuel which diesels cannot. In theory, you can even burn prepped refuse. With care, they have a long service life. With new combustion technology developed by Porta, they are efficent users of fuel with greatly reduced emission problems.The disadvantages are they are labor intensive, cannot be mu'ed ( at least now-if you discount the ACE design which never got off the drawing board). The main problem is also the secondary cost of reinstalling service facilities. The only disadvantage of diesels is the fuel they burn which is becoming a problem that will only grow worse with time. I expect to see studies made by the Class I's in the next few years to study this problem of fuel supplies. Where is the tipping point? It's a moving target I cannot predict. I am no expert. It's an interesting topic that is seemingly inexhaustable.It's amazing that nearly 50 years later, the "debate" continues.

Nothing is more fairly distributed than common sense: no one thinks he needs more of it than he already has.

...primarily because the gap in cost between coal and diesel fuel closed. ACE 3000 was pitched at a time when the price gap between coal and oil was very high. Later on, there was a very large gap between the cost of oil and nat'l gas that led to some work on using CNG and LNG as locomotive fuel. That interest also evaporated as soon and the price gap closed.

I think you missed your own very good point.

If 90% of the traffic goes away, so do the fuel costs and maintenance costs as well. Employees can be furloughed. With Dieselization, one big cost thereafter remained that railroads could no longer control: the interest charges on the investment.

It may be that 90% of the traffic goes away, but 40% of the cost remains even when the shiny diesel-electric locomotives are just sitting there. Except that it becomes 80% or 90% of your cost and there's nothing you can do about it.

However, this does fit with your comment that railroad management at this point viewed railroading as a short term enterprise. Bankers, who benefitted the most from Dieselization, sat on most railroad boards at this point.

Walter Cummings, the chairman of Continental Illinois Bank, sat on the Milwaukee Road Board of Directors 1945-1966 ... it's most senior and influential board member during that era. When he retired, he was replaced by his son Tilden "Tillie" Cummings, by then, Chairman of Continental Illinois Bank.

Dieselization performed as promised on fuel and maintenance. Inflation adjusted (1944) maintenance costs for the Milwaukee non-Electric fleet went from 67 cents per 1000 GTM (average, years 1945-1948) mostly Steam, to 53 cents per 1000 GTM (average, years 1958-1962), all Diesel.

Michael:

I don't mean to nitpick, but on page 11 you stated the following:

"Maintenance costs of motive power per revenue ton were, if anything, overall slightly higher after dieselization than before. Where's the benefit?"

"Fuel costs are slightly higher after dieselization than in 1944 when Milwaukee operated 1094 steam engines and only 79 diesels. Where's the benefit?"

Could you clarify whether there were savings and why the conclusion has changed?

Thanks

That's a fair question. In this instance, the units measured are different. Compared to net tons, the relative costs of motive power operations increased. Compared to ton miles, the relative costs of motive power decreased.

The capital costs of conversion to steam would only duplicate the same problems encountered with Dieselization. As I mentioned early in this thread, making the same mistake twice doesn't fix the first mistake. Dieselization would have been a net benefit, but for the means of achieving it, which wrecked the whole endeavor. As to pollution, combustion by-products present difficult problems whether from internal or external combustion engines. Diesel engines have been much less susceptible to the proven solution of catalytic converter technology which worked well with gasoline engines and other point-source pollution problems. Whether that would be true for the different pollution by-products from external combustion steam, or some internal combustion use of coal is, to my mind, problematic. Coal is a dirty energy source. On the other hand, hydrocarbon combustion in general, including Diesel, produces all manner of stuff that shouldn't be going into the air. Perkins, Cat, International and others have been working feverishly the last 15 years anticipating higher emission standards for Diesel truck engines. They have devoted enormous resources to the problem with only marginal success. It has been a tough and expensive problem to overcome.

I can hear you guys now ,thats 8,000 tons less,ahh touche but they had fricton bearing's. Not the nice roller bearings that todays power house junkers get to pull. Took 4 count em 4 to get the same train pulled by one steam loco.So before you all say steam was horrible l suggest you re read your history. Had WWII not forced railroads to run power that was beat up and out of repair the diesel might have had to wait till the 70's.
Funny we all talk about how great diesels are and versatile but can a 70 mac do locals? a Trash 9? I dont think so folks! Diesels were versatile one day long ago,not now.
There are some fundemental differences in the way trains were operated .
In the old days it was not unheard of to exceed speed limits, you could get a good run at a hill whereas nowdays you cannot !!!
iT'S NOT JUST THE LOCOMOTIVES THAT CHANGED RAILROADING !!

Anthony,
I just found some data and analysis last night from the early 60's on the improvement in efficiency brought about by diesels. I think there is probably a wealth of data and analysis out there in various company archives on the subject.

That's a fair question. It depends on the unit of measure. By a revenue ton comparison, costs went up. By ton miles, they went down. Depends entirely on which measure you might think most important.

This may have sounded counterintuitive. It was a statistical fluke in this case.

Revenue tons, 1945-1962, decreased by 24.5%. Line haul increased from 348 miles to 358 miles and so the ton miles decreased by only 22.1%.

Adusted fuel and maintenance costs decreased by 22.8%. So, relative to revenue tons, these motive power costs appeared to increase per revenue ton. However, relative to ton miles, motive power costs appeared to decrease per ton mile.

Had these cost percentage declines been greater than 24.5%, or less than 22.1%, the comparison with either revenue tons or ton miles would have been identical that is, representing an increase in such costs over the study period or representing a decrease in such costs per unit measured over the study period.

A fluke, but accurate.
