[@missyd0g2]

I love that big steam locomotive. A little fun fact. When the Blue Goose airplane arrived at the Henry Ford back in the 1970’s. I was one of the team of volunteers who helped put the wings back on. The Henry Ford and Greenfield Village has amazing volunteers. Very nice video

[@williamkeith8944]

About 5 years ago I was awakened by the sound of a steam whistle near my suburban Houston home. Lo and behold it was the Union Pacific "Big Boy" in town on tour. Magnificent engine and tender. Back in the summer of 1971 when I was in college I worked for the Santa Fe Railroad in Pampa, TX where they had a work train set up to weld 37 foot lengths of track into quarter mile sections. I had a job to use a pry bar to align the track as it emerged from welding onto the quarter mile of rail track cars; there were slots to hold 24 quarter mile sections. Up and down, pry and push as the 37 foot welded sections came out every 5 minutes or so. It was a grimy, boring, laborious job that paid well. I suppose that describes most railroad jobs. Thanks for this video, the days of steam railroads were glorious and opened up America for commerce.

Hope to get there one day and see it first hand.

We had engineering drawing as a subject and there were draughtsmen to prepare the blueprints.objects were translated according to blue prints. Only cut n paste was not there so any correction was either remake the drawing or add a correction slip. Was a wonderful time and one practiced engineering out of ones mind rather than computer base data. Of course there were data manuals to refer to. In fact all aircrafts were on blueprints also. Drawings were quite accurate so to speak for. Well cad cam has eased everything but only drawback is less of human intervention and any programme is only as good as its programmer

[@brenthill3241]

A magnificent machine. I stuck my head underneath and checked out the massive foot thick steel frame at the front along with those huge leaf springs when I visited the museum back in 1982. Yes I've been thinking it would be great to see one of these run now that a big boy is on the rails. The locomotives are close in weight with this early H8 at 389 tons less the tender and the Big Boy at 384 tons for the early series and 386 for the second series so maybe a few miles of rail could be spared for historical purposes. It definitely had the clear edge in power.

The Allegheny was always my favorite big steam locomotive, even more so than the Big Boy. It was just a beast of a locomotive, and I thought it was the best looking of all the big articulateds. Just my opinion...I do like the Big Boy, though, and it's good to see the 4014 back on the rails!

[@markantony3875]

The Allegheny never put out 7400HP. That was an outlier on the drawbar scatterplot while the test train it was pulling was coming out of a sag in the track. It put out 6600 to 6700 HP at the drawbar, still the strongest drawbar HP of any reciprocating steam locomotive.

[@gingerbread6614]

[@travelingtom923]

Thank you.

[@Martin_Adams184]

Thank you and well done! This is a video tour that lets sight do its own thing - no drawling commentary on how the locomotive is heavier than 500 double-decker buses (but how heavy is a bus?) or that demonstrates the commentator's limited knowledge. What we see here is what happens when you walk around the exhibit. Lingering here, lingering there, peering at this detail, stepping back for a wider perspective. Great stuff! It leaves me with a strong awareness that this 2-6-6-6 is an awe-inspiring piece of engineering.

[@09JDCTrainMan]

The Alleghenies, though heavy nor having THE biggest boiler, likely has the best boiler while still being huge, at 109". It can average 6,700 to 6,900 drawbar horsepower, sustain a max of 7,375 DBHP and can peak at 7,498 DBHP at 46 mph, and runs on just 260 psi. Boiler pressure alone doesn't pay the bills, hence why it can still produce a lot more DBHP than the Big Boy, which operates at 300 psi. The Allegheny's steam generation is also superb, likely able to generate more steam than any other steam locomotive.

[@travelingtom923]

That's right. Many experts believe this locomotive had even more power than previously stated on paper. It was a fantastic and well designed locomotive for its time.

[@09JDCTrainMan]

@@travelingtom923 Yeah. What I found out is it's because of the superior design of the steam passages to the steam chest, and as a result, a higher steam pressure is going into the cylinders than the Johnson Bar (reverser) indicates. An Allegheny exerted up to 119,500 lbf of starting tractive effort with worn 65.5" drivers. Going by the usual calculation of .85 (85% efficiency), it should've exerted only 112,735 lbf of starting tractive effort, but with the superior steam passages, it was actually working at slightly higher than 90% efficiency (.9%). It's the slightly higher than 90% efficiency that it was able to exert that 119,500 lbf figure.

It's highly unlikely, unfortunately. Unless CSX decides to start their own steam program, I'm not sure who would have the money and facilities to do it. I've heard they've permitted 2716 to run on a section of their system, but that's a much smaller engine. At least the WMSR is restoring 1309 for us to enjoy (it's like the Allegheny's "little" sister).

[@FS2K4Pilot]

It would be easier to restore this engine, rather than the 1604, because this one had just been freshly shopped before the C&O sent it up to Dearborn under its own power, and on top of that it's been indoors in a climate-controlled museum the entire time, and the tracks that it got into the building on are still there. On top of that, the Greenfield Village Railroad has sidings it could be put on for work, plus the Roundhouse has steam mechanics and machine tools needed to work on it, including a wheel lathe. Furthermore, Dearborn is less than three hours' drive from two major organizations with extensive manpower and experience with the restoration, operation, and upkeep of Lima-built, Van Sweringen-owned Super Power locomotives: the Steam Railroading Institute in Owosso MI, keepers of the Pere Marquette 1225, and the Fort Wayne Railroad Historical Society in Ft. Wayne IN, keepers of the famous Nickel Plate 765. I would think that between those three groups, you'd be able to muster most, if not all, the resources and know-how to steam her back up. Of course, you might also need help from the folks on the Western Maryland Scenic Railroad, for dealing with aspects particular to an articulated locomotive. The biggest difficulties I can think of (there's probably more) are: 1) Getting it out. Not only will you have to temporarily remove the equipment displayed behind the locomotive, but the curvature of the track going into the museum is so tight that the engine derailed seven times going around it when they first stuffed it in there. 2) Even with the facilities and trackage they already have there, you'd need to make a concrete work area and inspection pit suitable for jacking the locomotive up and removing the drivers and wheels from the locomotive and tender (maybe a full enclosed engine house with overhead crane) plus you'd still need to strip it down to bare boiler and frame, ultrasound the boiler, maybe new flues and sheets (God only knows what if any kind of lay-up they did on that boiler when they stuffed it in there), check the staybolts and caps, plus rebuilding or reconditioning all her running gear and appliances, maybe trueing and reprofiling her wheels, possibly new bearings, rebuilding her brakes, a new brake stand, plus God only knows what else. 3) All of the above takes time and money and labor, figure $2,000,000 and one or two years of labor, not counting work on the facilities. 4) Of course, the biggest pain in the d!ck of all will be scamming CSX into letting anyone run the bloody thing anywhere on their system, assuming that clearances and track alignments on their system will still accommodate such a giant locomotive. A Pacific or a Berkshire/Kanawha or a Northern/Greenbrier type is one thing. An Allegheny is something else again. I'm not saying it couldn't be done, and I certainly have my hopes, but it would be easier and cheaper to buy a scale model from Rivarossi or MTH.

[@luckygour3241]

Wow.. Great video 👍👍

[@rogerwhittle2078]

Now, see, this is where my engineer's sense of form and function sets off alarm bells. Yes, it is a most amazing example of extreme engineering, yes it would be interesting - in the same way NASCAR racing is 'interesting' - to see it steamed again. The same goes for almost any preserved steam locomotive, but you wouldn't want it to go on a near nationwide tour to show itself off, would you? Inevitably #1601 is compared directly with the UP 4000 class of which there were 25 - I don't know how many of the H8 class there were. The UP Challengers (4-6-6-4) were about 628,000lbs (280 long tons - not incl tender) while this thing was 778,000lbs (347 long tons) 67 long tons more - almost the weight of a good sized British tank engine - on the same wheel arrangement. Just that fact scrapes the inside of your skull, like a fingernail down a chalkboard. The UP Big Boy was 340 long tons with 30% more driving wheels! It's all very well claiming world records (14,000 ton freight train etc.,) but that was once. The Big Boy was designed to pull 9000 tons over Sherman Hill unaided and it did. Day after day, year after year, doing what it was designed to do. Yes the #1601 is an intriguing thing to look at, but it ain't handsome. #4014 is seriously handsome and although huge, it is nicely proportioned and is obviously the logical extension of #3985 (UP Challenger) which is downright good looking. There were 105 Challengers, so they were doing some good somewhere. So, it is good that #1601 is sympathetically preserved, but please don't dream of ever steaming it again. Because it will only prove once more, just what a rush of poop to the brain it represents.

[@stephensmith799]

@@travelingtom923 Generally US steam design was ahead of the UK. Eg long travel/ long lap piston valves and high superheat were adopted by the GWR I think following the lead demonstarated in US pacific designs in the early 20th C. Crew conditions were far better in the US till at least the 1940s with cab controls laid within easy reach, steam reversers and of course mechanical coal feed instead of hand firing. I know traffic conditions were extremley different but for example in some British designs it was not possible to reach the brake handle while looking backwards from the cab while reversing onto a train. GWR tender locos did not even have cab doors... ever! For mechanical sophistication the French ended up ahead but at a price in terms of maintainance. Interestingly British steam built by private manufacturers for export was up to modern standards particularly as built by North British at their Atlas works in Glasgow for South African Railways. Most British railway companies built most of their own locos. The Midland Railway was famous for its backwardness even by British standards... small locos, short travel valves inside valve gear and inadequate wheel bearing surfaces even in their 4F goods locos built by the company's successor, the LMS. Obsolete from the day they were built. As for British Three Link Couplings... they led to many hundreds of deaths among Shunters who had to step between vehicles to throw the links over drawhooks or else flick them over the hook from outside the buffers. Many died crushed between buffers. Most freight vehicles had hand brakes only which were operated on the move by a shunter using a pole to lever down the brake lever. To apply enough force they rode the pole putting their whole weight on it at about 10mph... running alongside each vehicle to get the pole in place then leaping on to ride it on their stomachs. Lethal and ùtterly backward compared with US 'knuckle' automatic couplers. Three link couplings allowed very small locomotives to draw rolling stock forward one truck at a time to put in enough momentum to tug the last vehicle, a brake van. Small locos, long trains and three link couplings were very poor indeed.

[@DeCasoU1]

@@stephensmith799 Hollow stays were found on a few British locomotives but given that arsenical copper fireboxes with a range of staying materials depending company practice, stress levels to be dealt with, best suitability etc formed by far the majority of fireboxes on British locomotives it is clear that the companies involved had good reasons to adopt this practice and in the main continue it to this day. The Institution of Locomotive Engineers papers can shed a great deal of light on the thinking taking place. The subject of long travel and long lap valves is tied in with trying to deal with lubrication and wear issues, also the use of narrow versus broad valve rings. There was a great deal going on at the time, the introduction of the narrow rings was felt by some to be more beneficial than the introduction of long travel and long lap valve gear. Locomotive cabs fitted with seats for the crew and well set out controls came into use in the 1920s, you don't need power stokers on grate areas of 50 sq ft or less, nor do you need a power reverser, unless your valvegear is inordinately heavy and lacks balance weights or springs. The Midland 4F was not the best design of its type but the idea that the wheel bearings were undersized is not correct and you can buy a book explaining all of this. Give yourself a start by checking out the size of the boxes fitted to these engines in comparison with engines of a similar size and type from the other companies. It was powerful enough for the work it had to perform, large trains were seldom needed in the UK. No one stands between the buffers they are usually touching or very close to it. The main problem comes about when someone moves the train while coupling work is being carried out which is why the brake hoses are uncoupled to make sure that nothing moves while you are either swinging the buckeye or working on the screw link, this assumes fitted stock. The UK did have a large legacy stock of unfitted vehicles and companies were making efforts to move to fitted freight trains before WW2, and now things get complicated because the Government decided that all freight stock should be nationalised for the good of the war effort. In the UK there were a large number of privately owned freight wagons and these were taken up into railway company ownership and if you believe that the Government picked up the bill, think again. So there you are trying to modernise your freight services and a war comes along and you are forced to take on thousands of vehicles at significant financial cost. And the rest is history. The problem was that the railways expanded very quickly from basic industrial beginnings and the growth produced a number of issues that became very difficult to address and the unfitted goods wagon was just one of them. There were accidents, thousands of them, unsafe working practices were a major issue. You can work unfitted stock relatively safely, the preservationists keep the art alive to this day but they have the time and the training to carry the task out. Inadequate training coupled with commercial pressure, less than ideal conditions which could be pretty poor anyway with all the noise and you had a recipe for carnage. Rather like the chain brake the loose coupled freight train lasted longer than it ought to have done. The French were good at thermodynamics, their drawing office practice left something to be desired.

Hey Tom. What kind of boiler pressure do these run? Are there water tanks in that trailer? How far could they go on one fill-up? You said it was to heavy for some tracks back in their day, so if the big boy is heavier, how do they manage to run it around nowadays? Great video. There sure are a lot of valves in that cab. Are some of them for bypassing bigger valves to bleed small amounts of steam in the lines to preheat them so they are not shocked by a large amount of steam hitting them all at once? I worked engine rooms aboard ship in the navy and we preheated all the lines with bypass bleeder lines when the boilers were lit off. That is, they bypassed the main valve in a line. Even with those heater lines you got a lot of nocking from cold lines being heated. That would flake off the insulation, asbestos, then you ended up with a very hot engine room!

The tender that follows behind the engine is indeed a water tank and fuel bunker carrying 25 tons of coal and 25,000 gallons of water. How far that will take it all depends on how hard the engine is working. A lot of those valves are just valves for shutting off/turning on miscellaneous appliances, such as the dynamo which generated electricity for the lights or the air pumps (mounted on the smokebox front)for the brakes. A good amount of the valves on the left hand side of the cab are for the fireman to control the amount of coal going onto the fire. As seen at 12:25 there's actually a mechanical stoker powered by a separate engine like you would see on a stationary steam engine assembly. It brings coal from the tender to the firebox through an Archimedes' screw and is moved into the far reaches of the firebox with jets of dry steam, also controlled by valves on the fireman's(left) side. These engines were equipped with what I call a 3-45 air conditioner- You open both cab windows and the roof vent and go 45 mph... and that's your AC! you have to stick your head out of the cab window a lot as the engineer on a steam locomotive anyway, that long boiler in front of you doesn't make for good visibility at all! And as far as their weight is concerned - The weight of the powered part of the Allegheny is heavier than the powered part of the Big Boy by about t3000 pounds. The Alleghenies were actually heavier than ordered. In fact, C&O sued Lima over the large difference in weight because Lima even tried to hide it. Running a Big Boy nowadays... well, the main difference is the C&O had different terrain to deal with than the UP. in the curves and bridges, quality of trackwork, tunnel clearances etc. etc. Nowadays with advances in technology, we could probably (theoretically) run the Big Boys on a regular basis on the UP and not have any significant difference in the amount Maintenance of Way needed because the quality of UP's mainline has increased greatly since the 1940's. Here's the specs of the Alleghenies and the Big Boys for comparison: Allegheny (Chesapeake & Ohio) : Wheel Arrangement: 2-6-6-6 Length: 125' - 8" Drivers: 67" dia. Weight on Drivers: 504,010 lbs Locomotive Weight: 775,330 lbs Tender Weight: 431,710 lbs Locomotive & Tender Weight: 1,207,040 lbs Grate Area: 135 sq ft Cylinders: (4) 22.5" dia. x 33" stroke Boiler Pressure: 260 psi Tractive Effort: 110,200 lbs Water: 25,000 gallons Coal: 25 tons Big Boy (Union Pacific) : Wheel Arrangement: 4-8-8-4 Length: 132''10" Drivers: 68" dia. Weight on Drivers: 545,200 lbs (second class) Locomotive Weight: 772,250 lbs Tender Weight: 436,500 lbs Locomotive & Tender Weight: 1,208,750 lbs Grate Area: 150 sq ft Cylinders: (4) 23.75" dia. x 32" stroke Boiler Pressure: 300 psi Tractive Effort: 135,000 lbs I hope you find this information as useful and interesting as I do. Locomotives are my main passion in life, and for as long as I can remember (about 20 years so far!) I've been studying them. Most of this stuff is recited from memory with minimal online/book research just to confirm some stuff I wanted to double check. false information is quite abundant in the world... I try my best not to contribute to it and instead put out only the facts!

[@cdjhyoung]

@@PowerTrain611 Why the Big Boy can still be on the rails and the Alleghany won't be is found in the axle loadings of the drivers: the Big Boy carries 34075 lbs. on each axle, the Alleghany carries 42000 lbs. That is a big difference.

[@travelingtom923]

@@TugIronChief To say it was a lot of labor is a understatement. Most of the fire arch is burned away in the smoke box. The fire arches only had a life span of about 30 days and had to be replaced. Lots of manual labor for that. Coal cinders constantly wore stay bolts down to thin metal in the firebox. I read that on some locomotives fireboxes had to be replaced yearly. This locomotive looks like a mechanical nightmare. Just fixing steam leaks was probably a full time job. You look at the guys working on these steam engines and the majority of the time they are old men!

[@ohboy2592]

cdjhyoung rails today have no problem holding this kind of weight. The rail used back then was much lighter and thinner than today.

[@trevo6213]

What an excellent video. I have a favour to ask though. My retirement project (or at least one of them) is to model this locomotive in live steam. I live in Australia and am not sure I am ever going to get to the US to take my own photos of the locomotive to enable me to design the model. Would it be possible to obtain a copy of the video so I can take still photos of some of the detail? Stopping the video on KZbin is always difficult to get the right spot but video editing software will allow frame by frame. All help is appreciated.

[@RocketStephen618]

Hey Tom, I love the Alleghenys. I'm glad you got to go see it. Where is the museum located? I would love to go see it one day. I hope you get to see many more steam locomotives in the future. Keep up the wonderful content! Best Regards - U.P. 4014

[@drtidrow]

Dearborn, Michigan, a suburb of Detroit. Greenfield Village, right next to the Henry Ford Museum and part of the overall complex, has several operating steam locomotives that convey visitors around the outside of the village. Well worth a visit to both if you're in the area.

[@SledPrn6]

If you do go to the Henry Ford Museum in Dearborn MI where this beautiful engine lives give your self a FULL day if not two. If you hustle you can cover the whole place in about 2-4 hours, but you are just selling your self short of enjoying everything this place has to offer!!! I've been twice with FFA and later with my colleges Auto club for spring break. Both times for only a few hours, and foolishly I made the mistake of saving the trains for last, both times get to this engine and it was time to leave!!! hoping to go back on my own to really enjoy the place and start at the trains!!!!!

[@drtidrow]

@@Laura-6887 Or get the annual pass and go whenever you have some free time... though not right now, what with COVID19 and all. Definitely worth it, though - always like to go to Motor Muster in June, which is a big car show for cars made in the period 1933-1976. In September they have the Old Car Festival, for cars built earlier than 1933. Over in the village, they play historic baseball games on summer weekends in Walnut Grove Field, using 1867 rules, which means no gloves for the fielders, strikes and balls are normally not called, and the pitcher pitches underhand (much like softball). Perfect way to spend a sunny summer afternoon. ^_^

Awe inspiring! But think how much coal would be needed just to move itself along the rails!

I remember reading that you could put a table in the firebox and have 28 people eating dinner at the table.

[@travelingtom923]

@@TugIronChief Yes there is no way you could hand fire that locomotive. Probably shovel coal all day long and not even raise the steam gauge off of zero.

[@FS2K4Pilot]

Traveling Tom I've heard of one Big Boy that had to be hand-fired light from Laramie to Cheyenne (Last of the Giants Vol. 3). The dispatcher wanted to assign them to haul a train. The fireman had other ideas. I believe that he and the head brakeman took turns shoveling coal. Fortunately things got easier once they got to Sherman and started heading down grade.

[@dodgydruid]

Wow that is sure bigger than our humble BR class 9F 2-10-0, it even puts to shame our Beyer-Garratt's which were monsters of their time, shame to see it static and not actually moving but I imagine with the state of some of the US's wooden sleeper lines it would be pretty hard to keep on rail and prob give some of the concrete stuff a headache.

[@FS2K4Pilot]

Our mainline track is pretty strong. It's really a matter of just using properly hefty rails and sleepers (or ties, as we Yanks call them). I couldn't tell you about the ties, except that the wood ties can stand up to plenty of abuse, and the concrete ones are even tougher. The rails, however, run between 131 and 160 pounds per yard (0.9 meters), and they can handle 15,000 ton freights, or cars or locomotives with axle loadings of up to 80,000 pounds. This locomotive comes in right about that heavy. It wouldn't be gentle on the track, but the track could handle it.

[@Deadbuck73]

[@aaronbonatz9485]

Is the UP Big Boy locomotive still bigger than the Allegheny H8 C&O?

[@scottgriggs2596]

@Aaron Bonatz Yes, the Big Boys were longer, heavier, and had more starting tractive effort than the H8. The Big Boys were also rated to pull much heavier trains on comparable mountain grades (4450 tons on a 1.14% grade for the Big Boy, compared to 2950 tons on a 1.14% grade for the H8 Allegheny). The Alleghenies did have an edge in horsepower above 30 mph.

[@scottb8175]

Lots of info on the "biggest" steam locomotive at steamlocomotive.com. These C&O Allegheny where reported to be the most engine weight, weight on drivers, boiler size, and draw bar horsepower (actual measured pulling force on a train at speed using a "dynamometer car") at 7500 DBHP. But other locomotives, including the Big Boy and DM&IR M-3 & 4's could have been coaxed to high DBHP for short distances, too. Too many variables are involved to make any meaningful direct comparisons. Even N&W's 600's made short duration pulls in excess of 6500 DBHP, and those are much smaller and lighter locomotives. But other locomotives had more tractive effort (TE), total weight, etc. Some lesser known of these monster articulated steam engines made unbelievable claims on pulling power, like the N&W Y6B and WP M-137's (which should have nearly the same as the much lower TE rating as SP's AC-11/12 Cab Forwards, as the WP and SP locomotives are nearly identical Baldwin designs). Very good that 1601 survives in good "unrestored" condition at the Ford museum vs. rusting away in some outdoor park display. Very unlikely it will ever be brought back to operation, though. The cost would probably far exceed what UP spent on 4014 (which was extremely well cared for while on display in Pomona and thus in better condition before restoration began).

[@alzinn8231]

The real issue here is not which one had more horsepower or tractive effort, but the fact the the 2-6-6-6 Allegheny was really a poor choice for what the C&O needed - i.e. a mountain coal hauler. The would have been much better served by a modern Yellowstone type, such as B&O's EM-1 2-8-8-4. The Allegheny 2-6-6-6 was built because the head of the design team, Dan Ellis was obsessed with beating the N&W class A 2-6-6-4, even though N&W used their A's primarily as flat land haulers. It was Ellis who forced Lima to hide the excessive weight of the completed locomotives, even falsifying the weight certificate at time of delivery. The Allegheny may have been slightly more powerful than the UP Big Boy, depending on how you measure power, but that misses the point that the UP engines all came in within their design requirements including axle load, while the Allegheny was way overweight. As far as tractive effort goes, the DM&IR Yellowstones were more powerful than either, and the PRR Q2's made more horsepower. The Allegheny is a magnificent beast, but the UP Big Boy was a better locomotive.

[@markantony3875]

The EM-1s were never designed to lug coal either. The had an articulation joint between the front and back drive wheels designed for highspeed stability and the produced their maximum HP from 40 to 50 mph. They were purchased by the B&O for higher speed general merchandise and express train operation. They ended up pulling Great Lake bound coal trains and the end of their careers after all the main line trains were dieselized. That's when most of the photo and films were taken...when people realized it was only a matter of time before they were scrapped like the rest of steam.

[@DeCasoU1]

@@Automcanic For the weight of the locomotive it is poor. 5,500 indicated horsepower, giving slightly more than 4,200 hp at the tender drawbar, can be delivered by a locomotive weighing 326,284 lbs. The Allegheny class weighed in the order of 751,830 lbs and had far too much weight on carrying axles.
