The BIG BOY needs a DIESEL HELPER? Why?

[@msb3175]

I agree with you 100%. As a Conductor I piloted 844 over Donner pass in 2012. There were a number of people that argued the need for the diesel helpers on various KZbin videos. After a year I finally chimed in and explained the real world to them. My main point beyond the physical needs was that there is no reason to work a one of a kind (so to speak) essentially hand built piece of history any harder than needed. Burn up the modern units that are in the hundreds so the old horse can continue to make the show.

I do remember a time some years ago where a breakdown of the diesel engines resulted in the Challenger being commandeered to pull a 143- car container train. The train was going to Cheyenne, and since the Challenger was already going there, anyway, the crews just coupled it up to the freight train and away they went. It did the job with no trouble and no diesel, so, yes, these locomotives are still quite capable of pulling a huge load. It's just a lot less expensive with diesels.

Well said, from both of you. I’m a weird sort, so they say, and I do a lot of research. I agree that having a diesel to save fuel for the steamer is a good idea. So, from the guy who has studied the history, and now works in the modern day… The Big Boy can’t just be shut down in the middle of a trip, that would damage the main cylinders in short order. Brakes, they would be hard to find these days. Shoes would have to be fabricated at a high cost for the application, because the run would be so small, not to mention having to be upgraded with modern materials. Fuel, well, the conversion to burning oil helps to transport and deliver as opposed to trying to get coal to who knows where these days, and then load it… Water, not only would a city supply be a bit taxed in some smaller towns, it also has to be tested, and the additives put in. Judging from the extra tenders, I would say that there is at least 20,000 gallons behind the old boy. Big Boy locomotives never pulled passenger, so there is no electric or steam to supply those cars with. The sand makes a mess, it gets crushed to dust, and blow everywhere… I would love to see the engineer getting out with an oil can to add a bit of lube to bearings during a water or fuel stop! PTC has been used on steamers in the past, picking up a signal from the rails. They still send signals through rails these days. Put a transistor AM radio set where there is no station near a mainline rail and the signal becomes audible, but don’t trespass where you shouldn’t be.

As far as I know, the brake shoes are not modern, they’re still using the same cast iron shoes they’ve always used. The difference is they’re not ordering thousands at a time, it’s just a couple hundred probably, if that. They’re bound to be pretty heavy for a machinist to hang one when it’s time to change it too. I’ve changed a few normal sized cast iron shoes on some SW 1500 switchers when I first went to work on the RR and they were pretty heavy and had 4 shoes per axle on units with double clasping brake shoes, but then we went to composition shoes on everything, and now it’s been 10+ years since I’ve seen an SW 1500 or even an MP 15 on the property. They’re building trains in our yard using SD 40-2’s and slugs made from SD 40 and SD 38 locomotives now.

[@paulholmes1303]

Having been around steam for many years of my youth (I'm 68) living a few miles from the Edaville train in Carver, Mass (hearing the whistle everyday!), well aware of the logistics of the Steam system. Out West, you do see the odd water tower by the tracks but you are very on point with the logistic pipelines that were eliminated/lost when diesel was adopted. Water was always the limiting factor for steam, and if we had never retired steam, we would be dealing with supply chain delays through the odd drought years more than anything else. After a few years stationed in England, had a chance to see an old water track (dry of course) used to replenish the Steam Expresses from London to Edinburgh. Trains could fill their tenders at speed with scoops, and reports were the water spray halo as it raced down the track was something to behold. Trying to fill a Big Boy with that system would take miles of flat trough. Thank You for your instruction and information, Sir!!!!!

[@FortunaFortesJuvat]

With British steam railroading, the challenge was always the small British loading gauge- you needed locomotives that were smaller than 73' long (including tender), 13' 2" high, and in many cases 21t axle loading to cope with tight curves, light rail, and Victorian bridges. Track pans, compounding, top quality Welsh steam coal were all part of the equation!

Excellent explanation about this Diesel locomotive running with steam locomotive excursions. As a locomotive engineer I agree with your presentation and description.

[@brentboswell1294]

Class I railroads started requiring a diesel in the consist while there was still quite a few people in the operations department who remembered steam engines. As I understand it, they were afraid of a novice steam engineer running the engine out of steam, and fouling the main line for 30 minutes while building steam up again

[@the_retag]

Much worse and far easier in iems of no water towers would be running the tender dry. Atöeast droppig the fire on an oilburner is as easy as turning the fuel valve shut, but until a tankerload of water or another engine shows up a steamer with no watee isnt going anywhere

[@catherinehollabaugh1217]

Thank you so very much for the insights in your video. I inherited an appreciation of steam locomotives from my dad as a kid (I'm now 68). I hope you've been able to see Big Boy in person. They arrived late in Terrell, TX this week (8pm vs 4pm due to another trains issues). Even with the limited lighting, it was still impressive. I could remember my Dad's explanation from decades ago "a steam locomotive is like a living thing"". Thank you again for helping keep steam locomotives a living history.

I absolutely love your Band comparison, as a guitarist in a band myself, having to transport everything myself, being the one to set the rest of the band up, its tough and its stressful and it can really take the fun out of things. That all being said, what Ed and his team do really are amazing, considering that any part probably weighs as much as a full amp stack and then some.

[@ralfie8801]

I work in a large locomotive shop, there aren’t a lot of things we do to the engines or alternators that can be done without a crane or other lifting device. Ed and his crew don’t have the advantage of a crane while on a trip, short of renting a crane, at best, they could get an MOW mechanic to bring his truck so they could use the auto crane or hydraulic jacks to perform some smaller tasks that can’t be done by hand or with chain hoists.

[@joebond5012]

You have absolutely answered my long running bewilderment, as to why a massive steam loco needs to have a diesel running behind it. Thank you.

[@Green__one]

From a purely cosmetic perspective, I liked a solution that I saw a while back where a steam locomotive was accompanied by a custom diesel locomotive that looked mostly like a baggage car. You got to use the diesel for all the practical reasons you list here, but without ruining the aesthetics of the beautiful old train. I believe it was Canadian Pacific that did this, though I have no idea if they still do.

[@silvesterpeel5379]

Hello @Hyce, Your explanation of diesel engine assist is spot on. Here in Australia there is a nice steam loco R707 that has a restored vintage diesel engine fleet for its week long excursions. And another organisation Steam Rail Victoria has at times had diesel assisted trains.

[@STIX.TheMachine]

Only partway in, but on the bit about coordinating fuel loading, 4014 actually has a dedicated fuel tanker that does nothing but follow the steam crew around for fuelling at overnight stops. I have a picture of 4014 and the fuelling rig from the last time she passed through TX, I'll send it to you in a bit.

Yes there is a fueling rig that fallows the locomotive, but it only holds so much fuel.

Hyce, thanks so much for the explanation about all of the reasons why Big Boy runs with a diesel in its consist. I'm not a rail guy but just a fan and am incredibly impressed that UP decided to pull Big Boy out of Pomona to show the amazing technology that propelled our world circa WW2. Growing up in SoCal and enjoying the LA County fair, one of my very favorite activities, after checking out the amazing model trains, was to go over to the static displays of steam engines at the Pomona fairgrounds. I remember standing in the cab of the 4014 many times and wondering how this behemoth sounded like. I'm so thankful for the UP in having the guts and determination to bring her back to life to give us a sense of the role these amazing machines played in our history. Much appreciation for breaking down the realities of what it takes to bring this wonderful piece of history to all of us.

[@andrewweldy7508]

The 4014 is a truly impressive piece of machinery. I got to go into the cab of it about twelve years ago when it was still sitting at the Rail Giants museum in Pomona California. A couple years later I heard the news that it was going to be restored by the Union Pacific Railroad and while I was not able to be in Pomona to watch it get pulled out of the fair grounds I did a few days later go and see it in person for the second time when it was on public display at the Colton Railyard. Not only that but I went like many to see it as it was leaving California to be restored and then got to see it again in October 2019 when Ed and the UP steam crew made the run from Colton to Barstow. Honestly I like steam locomotives in general.

You did a great job my friend from what whet on from yester year to the day. Nice vid and I loved it.

As a fellow foamer...I approve of this video! Thank you @hyce!!! BTW, I have seen 4014 Big Boy in person, have photos, and videos. We chased it through Utah into Nevada and Arizona. Ed and his team are amazing to say the least. I have a new found appreciation for the logistics in the video. I made my own list before your video of what I thought it would contain. I got more than 50% but lacked many you had. I did have some others that may have been more obvious or not mentioned for one reason ro another. Still...great content, great video, and loads of respect for what you are doing.

[@ianlee3296]

It's definitely worth seeing the Big Boy in person. I've seen it twice when it came through Denver. The first time I met it out in Strasbourg for a short stop before it made its way to Denver for the night. The second time I picked it up from Limon and chased it back to Watkins. Chasing it was pretty fun as I was able to set up shots at different points of its trek. My favorite thing about the Big Boy is the whistle. It just sounds menacing when it goes past you.

[@bapadget]

Thank you for this. When I skipped out of work to watch 4014 pull into Colton, CA, I wondered why it seemed to be idling. A bit of thought, and a realized that, cool as it is, a Big Boy isn't up to the demands of rolling into one of the busiest yards in the US. Let grandpa rest, he's earned it.

[@Mr_Tea_Rexx]

I always was under the impression that the diesel is used for assisting in braking the cars and for the signalling / communications good to see this video explain it

[@fsj197811]

That was pretty good and makes a lot of sense. It's also vaguely sad. I'm sure Big Boy is pulling but in my head I'm kind of seeing it as a figurehead and the diesels are doing all the actual work. I'm more into WWII aircraft and they're nice on the ground but seeing them fly is TOTALLY different. Any equipment is the same way including steam locomotives so anytime they're working it's a really GOOD thing even if they need a little help. 🙂

[@muddynmonte]

Doyle was telling me one day that with as many guys as they have doping rods, they were running the airpumps constantly. It was getting to the point they were burning the compressor oil. Big Boys were generally greased using shop air. The diesel certainly aids in mobile facilities for providing "shop" air.

[@Hyce777]

Huh, that's a neat tidbit I didn't think about. Grease guns definitely eat a lot of air, that's for sure.

[@muddynmonte]

@@Hyce777 just don't try to run steam accessories on air and expect the same efficiency 😅😅😅

[@mitchellatta9808]

Thanks for this info. It confirms my thinking as to why the diesel was there. In essence, an interface between old hardware and new electronics, and systems. Elegant, simple solution. BTW, I saw one of these, under load, near Wolf Point MT., in 1951, on the way back from a visit to Yellowstone... We pumped our arm, and the Engineer blew the whistle... I was 5 at the time 🤓👍...

[@HoundOfBaskerville]

A point you missed is that some railroads don’t allow steam power, out here in Michigan we have the real life polar express (pere Marquette 1225) it has a diesel for the points that you mentioned but also to push it through towns or on other companies rails that have restrictions on steam power as well as to tow it backwards to the station so they can see properly

[@eddieschwab864]

Some railroads? I don't know besides UP, but CSX does not allow steam engines on its tracks...

[@HoundOfBaskerville]

@@eddieschwab864 glc, CN, NS all allow steam power within reason

[@joshuajensen2899]

I got the chance to see it come through near Cedar Rapids, IA and asked a similar question. Another reason for the diesel I was told is to give it some resistance for smoother starting. Since the power is so high, without a load, it’d take off flying while simultaneously slipping like crazy. In addition the diesel helps reduce flange wear by allowing it to push the big engine instead of it doing it on its own. When they were in Wisconsin, they had to oil the flanges to help protect them when negotiating some tight curves.

[@rearspeaker6364]

lots of curves have become tighter since the diesel came along.

If I'm not mistaken, and someone else might of mentioned this, but on the 4014's first big run, it did end up running out of water somewhere between New Orleans, LA and Texarkana, AR. I know I saw some video footage of the 4014 moving at cruising speed w/ no steam coming out which was pretty odd to look at but it was being completely pushed by the diesel locomotive to the next water fill stop. - Jason

I believe it was somewhere around Nachitoches, LA on its way to Shreveport. My dad had drove down to follow it north. They had to refill it with fire trucks.

[@alexphillips4325]

I’ve seen that vid. They cracked open the drifting throttle and just shoved it with the diesel. They eventually stopped to pump water from the auxiliary tanks into the tender cistern (instead of running them all connected as one tank) and then they continued pushing to their next stop.

[@ratheonhudson3311]

I have a lot of respect for locomotive engineers. They don't just operate the vehicle and then let mechanics maintain it. They maintain the whole thing themselves, they know it down to the bolts and what spare parts are on hand. I know some things about my car, which is small, but they know all the things about a huge locomotive that is many times their size AND is relied on by many more passengers and freight than a small car can handle. That's a huge weight on the shoulder and rails

[@Midland1072Productions]

Well this is a welcome surprise (wasn't expecting this today), love this video and the explanation :) On the subject of the Reading and Northern, for the 2102 trips. Diesels are still involved, just not on the train itself. They follow behind as protect power just in case something happens as it did on the Oct 8th fall foliage trip.

[@blackbirdgaming8147]

It also seems that R&N uses diesels in a similar fashion to UP when 425 is running. Pretty understandable given their territory, and that 425 is on the lighter side as Pacifics go. Can’t run it in the corner and all the ceiling all the time, and I’ll bet the brake equipment on those cars is expensive.

It is awesome to see live steam still pounding the rails here in the US. To have that live steam be the legendary Big Boy just makes it more awesome. However they have to run things to keep the Big Boy on the rails, I'm all for it. Since it's part of the plan, I am kind of surprised that the UP hasn't modified a diesel locomotive to look like either a passenger car or an auxilliary tender so that it blends into the consist.

Ed Dickens provided information on the locomotive servicing (including restorations), He did not do the excursion planning or the logistics. UP might used RAA source of information and practices. I hope you see that 3751 shows many of those elements that afford Railfan to spot and realize information value in OP's narration is one side (aka ED's version).

[@Comradedevmon]

I believe I actually got to talk to Ed when the Big Boy came to Texas. The way he talked about it told me he knows that train inside and out and what it's limits are with the current times. Of course he'd love to push it to it's absolute limit but with the way the American railroad is set up they just can't realistically do that outside of a short trip and not the miles long excursions they do.

[@MS-xh7cw]

[@johnandrobinmccoy8305]

I saw the Big Boy in person this summer, in Nevada. It was off the charts awesome. I also read somewhere that the diesel helper can push in the tunnels also. This allows the steam engine to throttle down in the tunnel, to reduce all the nasty smoke in the tunnel.

Ed and the Steam Team, are all super stars to me. And keeping the BigBoy in the best shape possible, to last as long as possible is by far a better choice than to just pull heavy tonnage for a photo opt. We all know what the BigBoy's are capable of!

But I get it, times have changed and ole boy is old and resources are not there anymore, but hey, us steam nuts can always dream it happening.

[@barryf5479]

I saw Big Boy yesterday and asked the Union Pacific employee the same question. His answer: Dynamic braking. He mentioned the steam locomotive had no problem with power. In fact, if you search youtube, you'll find a video where Big Boy pushes a stalled freight train on the tracks in Nebraska on the trip to the West. It had zero problem pushing the freight train from a dead stop.

[@FFred-us9tw]

The incident where the 4014 pushed a stalled freight train was NOT a freight train with no working locomotives. The train in question had 2 diesels on it and ONE of them failed. The other was working fine. The train was heavier than what a single loco could start on that grade. So the 4014 helped get the train started but the working diesel was pulling at full power. I know in the world of rail buffs they want to exaggerate these incidents to make them more exciting than they are.

Steve Lee was in charge back then, and he didn't care as much about the long-term preservation costs. As a result 3985 and 844 both got beat to hell; 844 needed a ton of work back in the early 2010s to become functional again. I remember seeing a photo of the inside of 844's boiler before it was restored: there was more boiler scale in the boiler than there was room for water. I'd imagine that 3985 is in even worse condition (UP chose to restore 4014 over fixing 3985!).
