Union Pacific Big Boy: The Behemoth Train that Tamed the Rockies

[@michaelloth6728]

As a 13 year old I stood in front of 4017 in Green Bay, WI. and asked the tour guide at the train museum if the Big Boy would ever run again. The answer was, "No". In July of 2019 as a 57 year old, I stood in Clyman, WI. and watched 4014 steam under the old coal tower that still stands there. My eyes were watering. It is a beautiful Locomotive. It also helped win WWll by burning coal and saving diesel for the war over seas. I thank Union Pacific for restoring one of these locomotives. It was always a dream of mine to see one operate.

[@nigelft]

That must have been a sight to be hold ... from a young man, being told to she will never run again, to being middle-aged, and seeing her moving, once more, under her own power ... Many may not get why it was such a emotional moment, but many of us, whom have been in preservation, conservation, and restoration, that getting a historical peice of engineering working again, is an incredible feat ...

Yes, the use of coal was a big deal in WW2 to save oil. The Brits preferred coal burning lend-lease ships from the USA, as they had plenty of that and no native oil supply.

As a boy living on a farm in rural Iowa, I remember the steam locomotives hurtling past carrying passengers and freight. You could hear them coming, then the ground shaking as they approached the lower field bound by the tracks. I would find an excuse for me and my dog, Brownie an Australian Sheepdog, to get close and marvel. Not certain if Brownie appreciated it as he would answer the train's whistle with his own howls. Everything is gone now; Brownie, the farm, the trains, even the rails. It's just me (old man) and my memories.

My grandfather was a boilermaker in Cheyenne. He was skinney enough to crawl inside the boilers to buck the rivets. He lost most of his hearing, ear protection was stuffing cotton in the ears. He retired in the late forties or early 50's. The smile on his face when we took him to a locomotive display was heartwarming. What an era to have grown up in. Steam locomotives are amazing.

It was a bittersweet day when they moved it out of the railway museum onto the UP main line to bring him back to life up in Cheyenne.

Finally got to see Bog Boy 4014 this afternoon; first time in my memory that I can ever recall seeing a functioning steam locomotive. Needless to say... it was absolutely awe-inspiring. The thing that took me aback the most was the sheer amount and force of the heat radiating off of him in all directions, regardless of wind direction. The ground-shaking was another crazy cool experience, especially when he went directly underneath a bridge I was standing on. It's really cool to see just how many people turned out all along the route to see him, and also the dozens and dozens of cars that followed him on the nearby roads everywhere. I saw him in the middle of Kansas, and the sheer volume of people that turned up to witness and follow him astounded me, and I was born and raised in this area. I've never seen such crowds before, and 4014 caused a traffic jam EVERYWHERE he went! The energy in the air at these gatherings was something very unique. Everyone was very respectful and courteous not only to the railroad staff, 4014, but also to each other. The air was alive with energy, people were non-stop gaping at the behemoth iron machine, and were all very excited. I've never even seen such enthusiasm from people at air shows with old planes. There's just something about the world's largest steam locomotive running I guess, especially after he sat for the better part of half a century! AMAZING experience, I'm so happy I got to see him on tour this year. I missed him on his first tour in 2019, but I didn't this time!

They are planning to go even further on the next tour, if you can go see the Big Boy it is awesome.

[@indridcold8433]

This behemoth has no dynamic braking. The brakes were only the steam actuated clasp brakes. When one sees this big guy on the rails, there is usually a diesel locomotive after the water car. That locomotive is not there to help pull the train. It is there to provide dynamic braking and generate power for the cars. The later steam locomotives do have steam driven generators on them but used a considerable amount of steam to drive the small generators.

[@LuckyBaldwin777]

I saw 4014 when it went through Tucson last year. First in line behind it was a diesel electric that the engineer said was just there for the dynamic braking. Said UP's rules require all trains on their tracks to have dynamic braking. He also said that it had been converted to oil for ease of refueling out on the line. The restoration job was amazing. Was quite a sight to see.

[@mikeeuritt4396]

your statement's first two sentences are accurate, the rest is misleading. Every single car in a train has air brakes since that technology was put into law. Two regular and straight air. All steam engines and modern diesels are equipped this way. The diesel is there to meet UP's requirement for dynamic braking not because the trains ran with no brakes. And since it is there and makes loads of electricity, run the cars power needs. Dynamic brakes are great foe mountain descents, having a whole separate system for braking is sound reasoning.

[@ZachPumphery]

@@mikeeuritt4396 There's multiple reasons why diesel locomotives are used, but the diesel locomotives that Union Pacific uses behind their steam locomotives do not generate power for the passenger cars behind them, this is accomplished by a dedicated car that carries a diesel powered generator. Other railroads or steam locomotive operators do occasionally include an actual passenger locomotive like one from Amtrak to supply the electrical power, but this is speaking specifically in reference to Union Pacific's practices. The diesel locomotives are used for their dynamic braking capabilities to lessen the use of the air brakes on the passenger cars. The passenger cars have disc brakes, which are unique in a fleet of millions of freight cars, and they are not interchangeable. It's a painful task to change passenger car brakes in the line of road, since they are not stocked across the system, therefore they try to avoid this by not using them as much. The steam locomotive itself is also not used for braking very often, as it too has uniquely sized brake shoes that aren't in wide supply across the system. As a matter of fact, the brake shoes on a locomotive of any type are rarely used for anything other than during switching or moving locomotives by themselves. In normal operating circumstances, the brakes on the train are used to slow or stop the entire train, leaving the brakes on the locomotives released until the train is below 10 MPH. In addition to slowing, stopping, and controlling the train's speed, the diesels are also used for additional power on occasion to accelerate the train at a faster rate, and they are used to keep the train at a constant "cruising speed" to lessen the use of the steam locomotive. This isn't because the steam engine is incapable of doing the job, nor to "baby" it, but rather to lengthen the range the engine can travel without replenishing water and fuel oil, a task that is time consuming and logistically impractical on a modern freight railroad that would be impacted by those delays. If the steam locomotive runs out of either en route, this is crippling to a freight network while a contingency plan is enacted to fuel the steam locomotive, not to mention it's not exactly best practice for a machine of that type. The idea of this is completely circumvented by carefully planning where the train will take fuel and water, and is almost always done during overnight stops via a strategically located water hydrant in proximity to where the train will layover, and a fuel truck that shadows the train's route. It's always better to arrive with extra water and oil than it is to run out en route. Very rarely does this ever become an issue, but when it does, it's an unnecessary challenge that shouldn't have to be dealt with.

[@kyleglenn2434]

Thanks for clearing that up. I always wondered why steam excursion trains almost have a EMD included.

[@InflatablePlane]

You can actually brake a steam locomotive without physically using brakes. By throwing the valve gear into reverse, steam entering the cylinder is now being compressed and absorbing work as opposed to being expanded and performing work. This provides a pretty powerful braking effect.

Not mentioned is why these locomotives need to be so heavy. That’s in order to generate sufficient traction between the wheels and rail to actually transfer all that power successfully. In the case of locomotives, heavier is actually better for tractive effort

[@muir8009]

kind of a good point. however it falls down a little bit when the replacement 4 unit f3's had the samish HP, double the tractive effort and half the weight. But (the big but) is of course the 16 driven axles of the unit as opposed to the 4000's 8, and just as important the consistently smooth traction motors as opposed to any big steamer having many tons of side rods thrashing around (hence duplexes of course, and why S2 could get to good speed with small drivers)

[@jdgindustries2734]

Steam locomotives developed their power in pulses... Each piston provided two power strokes, and since there was a piston on either side, set at 90° to each other, this provided four power pulses per wheel revolution. It was the tonnage of the engine that kept the wheels from breaking free of adhesion and just spinning the drivers without pulling the train. Look up "steam locomotives slipping" on KZbin to see what happens when the adhesion is broken. Because a diesel engine's power is first converted to electricity, then converted back to mechanical at the axle, it's power is delivered nearly smooth and continuously. This requires less weight to hold the adhesion you the rail. Modern 4400hp diesels have MORE pulling power than the big boys, yet weigh a third of the tonnage... Because their AC traction motors provide smooth continuous torque.

[@AugustusTitus]

The Big Boy made more tractive effort at low speeds, where the drawbar pull was measured for starting the train. Newer AC locomotives have essentially removed those limits on diesel locomotives.

[@guypehaim1080]

@@jdgindustries2734 When the adhesion is lost and the wheels spin, the tires become cold rolled and they loosen on the wheels.

[@Tom-Lahaye]

The weight mentioned for the big boy does also include the weight of the massive tender itself, plus 25,000 gallons (95m³) water and 28 tons of coal, a fully loaded tender weighed over 200 tons which is just dead weight and adds to the train load. So its weight has to be subtracted from the total to get the weight of the engine itself. So the engine weighed around 400 tons, resting on 24 wheels in total of which 16 driven, so around 2/3th of the 400 tons was on the driven axles. That's the adhesive weight of this locomotive, and is approximately 265-270 tons. A set of 3 F3 diesels had a total weight of between 330-360 tons, and all that weight was on driven axles, so the diesels had an advantage in adhesive weight over the Big Boy despite their total weight just being a little more than half that of the Big Boy locomotive. An advantage of the steam locomotive is that it can slug at a very low speed and maximum tractive effort forever as long as the boiler pressure keeps up, the DC motors in older diesels have their limitations, having to pull at low speed and maximum power for too long will make them burn out, and that's why diesels have hourly and 5 minute ratings, depicted by green, yellow and red sectors on the amp meters in the cab, green is safe for continuous operation, yellow means for max one hour and red is for short periods (like starting the train) only.

[@richardpare3538]

Bravo well done documentary and presentation on the Big Boy. The return of Big Boy 4014 was huge news in America. It's excursions on the UP railroad brought out thousands of people.

In May 2019 there was a grand event in Ogden, Utah that celebrated both the return of Big Boy 4014 and the 150 years since the completion of the transcontinental railroad. We were honored to have our song and video "Ballad of the Big Boy" literally open up this fantastic celebration and to perform live in downtown Ogden. It was just amazing to be a part of this event and equally wonderful to see the awe on people's faces when they fixed their gaze on the Big Boy for the first time.

What a nasty job maintaining the boilers. The scale build-up was VERY time-intensive to clean out, and all the moving parts had to be a devil to regularly lubricate. So glad we're done with all that hellish work. But, I love to watch the few that remain. Bigly!

My grandfather was an avid model railroad enthusiast. The top engine in his roundhouse was a shiny brass versioned the Big Boy. It was a rare treat to see that gleaming locomotive traverse the layout. When he sold all his MRR kit he got a tidy sum for that beautiful trophy.

For all the mechanical fury, these types of locomotives are surprisingly smooth. When I was younger a rail fan trip was coming through our town. My dad and I stood on the platform of an abandoned interlocking tower attached to a long trestle. A few diesel powered freight trains went by and the vibration was terrifying. When the rail fan special went by pulling the grade out of town, it was smooth as silk. Truly a sight to behold. I was hooked on anything mechanical after that.

[@guypehaim1080]

The exhaust steam from the cylinders is directed into a eductor which creates a low pressure in the soot box at the front of the boiler. This low pressure causes the air entering the firebox to push the flame and heat through the firetubes in the boiler to heat the water to steam. The reason the smoke chuffs and puffs out the stack is that the steam exhausting from the cylinders is intermittent, timed with the opening of the exhaust valve of each cylinder, which, by-the-way, are timed at a quarter rotation of the drivers. Reciprocating steam engines develop maximum torque at stall.

[@aaronwhitesell6418]

Just like a series wound motor. Greater the load causes motor to be further out of phase equals Greater torque.

[@ahseaton8353]

@@F-Man Steam engines lose out to Diesels in efficiency. The Grand Canyon Railroad had a diesel and a steam engine converted to burn diesel. When I rode them, they listed the drawbar tonnage pulled and diesel burned per hour on both in their literature. I did a quick calculation of tons pulled per gallon and the "internal combustion" diesel engine was 4 times more efficient than the "external combustion" steam engine.

[@dreammachine86]

So the fire itself is pushed through the tubes, or just the hot gases? I did wonder how the tubes worked in steam locomotives - whether the water was actually in the tubes and was then heated to steam, or whether the tubes run through a big tank of water that is heated by the tubes. And do all locomotive boilers have some kind of forced air draft to evenly heat the tubes, or would some just rely on having a huge bed of coal that runs all the way under the tubes?

[@guypehaim1080]

@@dreammachine86 The contents of the firetubes of the boiler vary according to the rate of firing which is proportional to the load on the locomotive. Some newer steam locomotives had watertube boilers, but there were few of them built due to the advent of the Diesel types. The firetube boilers have a firebox at the rear of the boiler which is separated from the water surrounding the tubes by a tube support plate. This plate is a water-tight partition. Try to find a copy of volume I of the Locomotive Encyclopedia to get the full picture of these boilers.

A nice surprise when I went on KZbin this morning! I followed the restoration via the videos from Union Pacific from when they first arrived in California to get 4014 ready to be removed from the museum (that alone was a feat I wish had been covered in this video), anticipating every next video. The meticulous work the UP team did was wonderful, not taking any shortcuts, making sure everything was done very well. The same with the restoration of UP 844, the only UP steam locomotive to never be retired, and deserving of its own Megaprojects video. The UP 3985 Challenger was slated to be restored as well, sadly UP management decided not to do it, even after new parts had already been acquired.

Patrick Rieger - IIRC, 3985 needs a lot of major work, and UP decided to put those resources into 4014. Fair trade, I think.

[@ralfie8801]

Bryan Noga They both needed many of the same parts, luckily a lot of them are the same between the two locomotives. When those shared parts were sourced from an outside vendor for the 4014, enough were ordered for both engines. They’ve said the 3985 is retired, but being they have a lot of the parts on hand, who knows if it’s permanently retired. It may be a budgetary thing at this time because the U.P. has been going through a major restructuring program for the last few years. Some of the 3985 is already disassembled inside the shop, but it needs the same kind of overhaul the 4014 went through, especially to the front engine and the frame. It wasn’t tracking straight when it was removed from service for boiler problems. There might come a day in the future when we see a Challenger and a Big Boy double heading again, don’t give up hope, all that needs to happen is for leadership to decide they’ve got a lot of the parts and the people to make the rest and turn the money loose to do the rest of the work to get it going again.

Many are commenting about the use of the term "train" in place of "locomotive." Although it is true that rail aficionados seem passionate about that point the railroads define a "train" as a locomotive with or without cars displaying flags or markers. If I had a book of operating rules handy I'd check the exact wording. Anyone here quibbling the use of the term "train" instead of "locomotive" should keep that in mind.

I never knew what happened to it, but in the last 20 years they have completely restored both the machine shop and the roundhouse, and refurbished the turntable. Lots of towns popped up when the railways were being completed, but the only towns that survived were the ones with roundhouses like Evanston, Green River, Rock Springs and Cheyenne.

When I first heard of and saw this locomotive I figure that they were oil fired. Because no way you could shovel or move that much coal into locomotive this size an even if you did the coal would all be bunched up on one end of a very huge firebox. Then I saw a video on how it has a screw drive that moves the coal from the tender to the engine and at the same time grinds the coal to smaller pieces just as your ice maker in your fridge does. Then an oscillating jet of steam shoots the chucks of coal evenly all through out the firebox.

Thanks. I've shoveled coal and wondered how this was done.

[@Nick_J_]

It should be noted Big Boy UP 4014 has been restored in 2019, as an oil fired

[@joshuajordan8574]

That screw is called a mechanical stoker. It would be extremely difficult for a person or persons to hand fire a large locomotive, especially while under loads. The mechanical stoker pretty much took over in the US after 1910 in most applications on most railroads. Big Boy 4014 was converted to oil burning when it was restored in 2015-2019. The stoker and all related equipment was removed.

[@joshuajordan8574]

@Sean Embry yes. I've read similar details. I really wish that Ed Dickens would post details on the oil conversion. It has obviously been successful.

The freight cars it sometimes pulls are there to provide braking. The brakes on the locomotive and the train operate independently.

Eh...not really. From talking to people who actually worked on it back in its heyday, it COULD handle higher speeds with little issue, but this would’ve increased wear and tear on the moving parts and that meant more maintenance and more frequent replacement of said parts (not to mention cleaning of the boiler and firebox), which UP didn’t want to have to pay for if they could avoid it. The REAL limiter on the speed of the Big Boy (and all subsequent locomotives) are the rails. Most curved rails in the US, especially in cities, turn too sharp for a locomotive going faster than 60 mph/100 kmh at MOST - any faster and the train will jump the track and derail. This is part of why high speed rail for passenger service never really caught on in the US other than in a handful of places - mostly on the East Coast, because nobody wants to go through the hassle of laying new track for it (and in many cases, they CAN’T).

Big Boy is incredible. My dad worked for the Union Pacific RR for many years. I've seen the Big Boy a couple times. It's awesome!

[@twentysevenlitres]

Simon and researchers. I think you miss understand the term "articulated" as it refers to the Big Boy. You see the Big Boy was built on the Mallet concept. The main frame did not bend or flex as you stated, it was in fact rigid. What articulated was the two engine units (and the leading and trailing trucks), such that you could have 16 wheels being driven by four pistons, for great power and traction, but in two rigid groupings of 8 making corners easier to navigate. The whole idea of articulated locomotives (of various designs) was to get the power of two regular rigid locos in one.

[@francisboyle1739]

Since the rear engine unit is integral to the frame and the front unit pivots against it I think "hinged" is actually a pretty good laymen's description.

[@AnthonyTolhurst-dw1nc]

Just like bogies were invented to keep carriage straight whilst pivoting on track changes. Last rode a steamer pax train in 1968. The black loco had a big smile painted on the front boiler access plate! Me? A boomer getting old!

[@twentysevenlitres]

@@MegaBoilermaker Big Boy was a Mallet. So was the Challenger, so was the Y6B and most other North American articulated types. Beyer Garratts had a double articulation with both leading and trailing tenders and were popular in Africa (particularly South Africa and Zimbabwe/Rhodesia) and Australia.

[@muir8009]

@@twentysevenlitres very close. out of the locos mentioned only the y6b was a mallet, the others termed rather simply as just simple articulateds. mallets are compounds with the same articulation.

Seen the BigBoy in person here in Houston,TX last year! The Union Pacific 4014 Bigboy well worth seeing under steam. The Hancock 3 Chime whistle shook the Amtrak station my friend and I were standing by the wall when they blew the whistle and we both had to wear ear plugs because it was so loud. Shook the whole ground and the walls. Also with the BigBoy the UP 4141 President Bush Sr. Presidential Locomotive was also with 4014 heading up to College Station. Was a well treated to see both In person.

[@KeithKman]

Forgot to mention they produce 7,000 hp! There is something about the Big Boys that’s hard to explain. They touch the human soul even for people that aren’t into trains. They may be man made, but they have a soul. You’ll understand if you ever see 4014 doing a high ball.

[@SharkyCartelRailroad]

They're rated only for 6000. They're matched by a Cab Forward and a bit less powerful than a Yellow Stone or Allegheny

[@alphazero2008]

they produce 6290hp top @41mph and 5600-5700 in typical operating conditions not very powerful to an allegheny which can produce 7500 top @46mph and 6900-6700 in typical operating condition the only advantage a big boy has against an allegheny is that it can produce 133,000lbs of tractive effort and the allegheny can produce 116,000lbs of tractive effort and 131,000lbs of tractive effort with a mini booster engine under the firebox, although these were not used because the limit of cars on a train for the C&O was 160 cars because they didnt want to have problems with trains waiting on sidings for signals, and the alleghenies could easily handle 160 cars or more, thus they werent used, so if an allegheny goes head to head against a big boy the big boy could start the train faster with more tractive effort, the big boy gets lost at 10mph+ with tractive effort lowering, and now hp matters at high speeds, with more hp the allegheny will catch up to it, high speed tonnage - allegheny always wins, thats what many rail fans or even normal people who think the big boy is the "strongest" engine ever, which it isnt

[@joermnyc]

There’s a video on here of 4014 leaving the restoration shop in Las Vegas... the sound of the whistle sounds like it’s waking the dead... and it’s not until it’s right next to the camera that you realize just how massive this is.

Many years ago I had an encyclopedia about trains and I remember a quote: "The first Big Boy No. 4000 entered service on 5th September 1941." Well today is exactly *80 years!*

[@nwngunner]

When the power goes out and the electronics fail, the big boy will still be running.

[@welsh_Witch]

Doubt it will

[@carlthor91]

If that happens, everyone, and I do mean everyone will be scurrying around trying to get enough food, to keep from starving to death, to worry about a loco. As much as I like it. Best wishes

No power, no electronics means no oil, coal, or gas and so no steam.

@@carlthor91 Worrying about a locomotive is highly conducive to the survival of a civilized society. Trains deliver food, products, resources, labor and news/mail. Without a method of mass transport what you're left with is scattered, isolated villages and the odd local feudal warlord

[@stevensolway1054]

BIG BOY 4017 at the NRRM in GB was the favorite exhibit when I Steven Solway, was the official tour guide, and full time paid employee from 1984 to 1989. Whether the groups were school children from kindergarten on a field trip, or then a group of senior citizens on a cross country bus tour. During the guided tour, the 4017 was still sitting outside, at first in front of the McCormick Train Pavillion on North track 1 and 4017 was pushed inside during the winter months to protect it from I've and snow. But in 1986 the former managers decided to Sandblast 4017, and use bright Yellow Paint as the primer coat. But those managers decided to switch some other engines and cars around to New spots, but sadly 4017 derailed the 4 middle drivers when the diesel switcher pulled it over the old rotted ties. Then we had to wait 5 days until the weekend, and the C&NW RR sent 2 of their GP-7 Diesels to pull 4017 back on track, and using a 50' Foot Gondola car as a spacer car. Finally after nearly 3 hours of dangerous work, they succeeded in getting the wheels back on top. The rails were repaired. And the 2 GP7's pushed 4017 backwards onto the new outside display track, and over the next 2 weeks, 4017 was finally repainted black with whitewalls on the drive wheels. The plan by the Board of Directors was to build a new Northside extension wall. But sadly that wall was Never Built. 4017 sat outside again for 14 years, and the new paint was completely destroyed. But in 2001 the new Exhibition Hall was built. 4017 was repainted black again, at even greater cost. Then shoved inside the framework of the new Exhibition Hall. And the walls built up around. And trapping 4017 permanently. It would be necessary to rip down the entire Southern wall to remove 4017 outside again !!

I'VE BEEN IN ONE OF THESE at the St.Louis Transportation Museum -- I have a picture but I couldn't find it -- truly massive but the actual compartment where the engineer would be is still relatively small.

[@josiahsansone6401]

That museum is the reason I got into trains as a hobby and that locomotive specifically. I have a working ho scale model of it and its one of my favorite things in the world.

[@ramblinman77]

Been there myself, even went in the cab and sat in the engineer's seat. Felt like a little kid and it was great!!! And yes, these things are truly massive.

That is where my interest in steam locomotives started as well. It's hard to appreciate the scale until you stand next to one.

The skill needed to operate any steam locomotive is incredible. But four sets of piston drivers, steam pressure, boiler temp, water level, speed, tube pressure everything the engineer and fireman had to watch all at once was just incredible.
