I think you guys are missing the question. Best freight locomotive? This has got to be the lowly 0-6-0 switcher. They outlasted the more glamorous road engines and probably throughout their life moved more freight then a given class of road engine. They could also go places where the others feared to tread. Some were in service for more then fifty years. I am sure if the diesels could be held to road service there would be some 0-6-0s working the yards today.
As for glamor? That would have to be the C&O /PRR 2-10-4. Functionality would go to the PRR I1sa 2-10-0. For the size it had 90,000 lbs of tractive effort at start up. It could be pushed to 50 mph. The all around bread and butter loco would be the 2-8-0. Thousands of these could not be wrong.

Well, I think if you go by sheer numbers, it would have to be the 2-8-2. But the six-coupled and eight-coupled were not really intended, nor purchased, as 'freight' engines. Yes, they switched in freight yards, and some were used on industrial spurs as 'road engines', but few of them. A Mikado could do the same job, but it was a much better handling, and safer, engine at track speeds.

Actually, builder statistics would show more Consolidations built than Mikados.

... East of the Mississippi? The C&O-NKP-PM-Erie 2-8-4...
The 2-8-4 is one locomotive that I never understood why it was built. If you look at the boiler on the typical 2-8-4, specifically the direct heating surface area, and compare it to one of the larger 4-8-2 Mountain types, there isn't much difference in steam production capacity. In other words, for the size of its firebox/combustion chamber area, the 2-8-4 really didn't need the 4 axle trailing truck. Tractive effort was similar between them too.
Take the C&O 2-8-4, compare it to a big B&O T4 or ICG Mountain, and you would not see much difference in boiler capacity. The biggest Eastern 4-8-4s, such as the N&W Class J, and C&O J3a had a much larger direct heating area than any of the 2-8-4s or Mountains, and certainly needed the 4 axle trailing truck to support it.

Perhaps so, but in terms of their overall utility (ton-miles), the Mikes would surely be the greater haulers by quite a margin. Just a small sampling shows their TE to be in the order of 5-10K pounds more than a sampling of Consolidations. They would have moved more tonnage at a faster pace as a class, depending on routing and loading. If they are second only to the Consolidation in numbers, then, when you think about it, it puts them at an advantage in determining overall utility, and thus places them ahead of the more numerous Consolidation Class.
I believe the key difference between a large 4-8-2 like the B&O T4 (ex B&M) and the NKP 2-8-4 is the grate area. Although the direct heating surface is similar (474 vs 461??) which also indicates that irebox volume may also be similar, the 4-8-2's grate area is 12% smaller (79 SF vs 90.3sf). In order to release the same amount of heat, the small grate area must operate with a faster burn rate in lbs/SF/hr. All other things being equal (which they never are), the NKP 2-8-4 would have a probable advantage by burning its coal at a slower unit rate.

That's only true if the quality of the coal was the same. Did the NKP have access to the same high quality steam coal the B&O did? The B&O (also C&O and N&W) used Pittsburgh coal (from various veins) that has a high volatile organic component that was gasified as the coal "cooked" on the grate. The gasified volatiles didn't burn on the grate, but ignited into a white hot flame up in the firebox and combustion chamber where most of the steam was produced.
Of course, if one does not have this type of coal, a larger grate area would be needed to produce the same heat output. What is interesting is that the T4 Mountain has more direct heating surface to absorb the released energy than the NKP 2-8-4.
Look, I wasn't "there", so all I know is what the books tell me. As far as the Berkshire type, some lasted right up to the end of steam, 1958-1959. A thirty year run for a locomotive type is pretty impressive any way you look at it. The "Big Boys", the record speaks for itself. You have to look at excellence of design, longevity, and the ability of the machine to do anything that was asked of it. Living in Virginia I could be parochial and say the best of them all were the Norfolk and Western A's and Y's, but I'm trying to look at the big picture. Some old timers I've met told me they used to chase the A's along Route 460 from Petersburg to Norfolk and the A's would run away from them, doing 70 mph+. A good way to get speeding tickets in those small "speed trap" towns! Of course, we could say the best freight locomotives were the humble 2-8-0's and 2-8-2-'s that lasted up to the end of mainline steam and beyond that no-one paid much attention to. We all have our favorites though, and that's a fact. Keep on chuggin'!
Erh – can we beef them up with best suitable coal specification? Will we be allowed to tune them up ever so slightly before the events?
Would it be considered doping to install high efficiency draughting Giesl – Kylchap – Lempor style?
What about if on my favourite last series cast steel unit frame UP-Nine 4-12-2 triple barrel stormer I were to throw out that grizzly Gresley derived valve gear and mount my home designed customized needle bearings Baker long lap valve gear of three independent sets, bore up just a little that cylinder in the middle to get more even torque (had shorter stroke), install Wardale type cooled valve liners and piston valves, re-surface all cylinders inner steam passages, then revamp the firebox design with shorter, deeper grate, doing away with Gaines wall, replace it by equivalent length of regular combustion chamber, revamp tubes arrangement for high superheating by A type superheater of SNCF 5P4 design, add two-stage preheater - or, preferably, have my new all-welded boiler design installed …
Ok, just dreaming …

This was an answer to the comment steam Olympics quoted below. It was meant as a contemplation on a transcription to classic steam of rebuilding / up-grading / customizing the way some owners of classic American muscle cars indulge these iconic automobiles with, or subject them to – depending on point of view and quality of work performed.

We need a Steam Olympics. How about in Olympia, WA?

Great idea. But I will repeat my own favorites. Non-articulated best freighter, the AT&SF 2-10-4. East of the Mississippi? The C&O-NKP-PM-Erie 2-8-4. Articulated? N&W A 2-6-6-4 I certianly can understand others having different favorites.
Juniatha,Must you write in that small print that is harder to read than the default size?
Quite frankly, I pass right on by all of your posts because, why waste my time trying to read something the poster obviously doesn't want to be read in the first place.
And, why is your post to "Steam Olympics" here under the "Best Freight Locomotive" thread?
.
Hey, Big Jim! A Juniatha post isn't something you can breeze through. You've got to slow down and savor it. A Juniatha post calls for a fine wine, a cheese spread, and some classical music in the background, say Wagners "Overture to Tannhauser." Something about that piece of music makes me think of a steam engine, Norfolk and Western's Class J for example. Don't know why, it just does. Yes, I'd like her print to be a bit bigger for those of us who's eyes aren't what they used to be. Or never were, for that matter!

With that combination, I think Jimi Hendrick's "Purple Haze" would be a better song.
The only thing "Purple Haze" makes me think of is where I put that bottle of Tylenol! I couldn't stand Hendrix 40 years ago and can't stand him now! Nuthin' but noise!
Think about it a little deeper. Purple haze really fits the bill.
OK, NOW I get it. The print color and the font. Still can't stand Hendrix. Or Jim Morrison for that matter. How about this: "When the deep purple falls, over sleepy garden walls...."
Juniatha,Thank you very much for editing your print. I really appreciate you taking the time to make your post so much easier to read. I hope others do to.
To get back on track: The Best Freight Locomotive. Nowhere is a mention of the 4-4-0 (American) Type. Admittedly they had peaked in the early part of the 20th Century, but they were virtually everywhere in the American Railroad environment. They were wood burners, they were coal fired and they were also oil burning.
They pulled freight and passenger trains. they were on mainlines; branchlines. all over the U.S.A., and Canada, as well. They were made by all the locomotive builders at one time or another. they appeared in a wide array of sizes and weights. They were ugly, and they were beautiful, a show of pride by their crews.
Here is a DL&W American about to go into the bore of the Manunka Chunk Tunnel in 1900.

Admittedly, this is a little far afield, but kind of interesting.
This is a link to photos showing this same location in recent pictures of the twin bore tunnels on the former DL&W that was baypassed when the 'Lackawanna Cutoff was completed]

Note: from the SHORPY web site referencing the term " CHUNK"
"...Only other "Chunk" name I've ever heard of that has been implanted on the landscape anywhere is the place in Pennsylvania once called Mauch Chunk. I wonder what "Chunk" in these instances means? Is it a land feature? (And hasn't the former Mauch Chunk been renamed "Jim Thorpe"?)
[According to the Interwebs, "chunk" is the Lenape Indian word for bear. Mauch Chunk = "sleeping bear" (after the shape of a nearby mountain). Can't find the meaning of "manunka." - Dave]..."
As the great Dave Barry would say, " 'Manunka is an old Indian word meaning 'Manunka'!"
