The World's Largest Overland Vehicles - LeTourneau's Land Trains

UPDATE - I went to see one of these IRL! • Inside The Insane 1960...
In the mid to late 50s and early 60s, a series of innovative and unique vehicles were tested in both the punishing arctic north as well as the boiling deserts of Yuma, Arizona. Some fo the longest and largest vehicles ever built, they were as strange and uniue as they were revolutionary. But who built these vehicles, why were they made and where are they now?

In my summer after the 2nd grade, my Dad (RG's son) came home unexpectedly in the middle of the day and told me to jump in the car. As we pulled away I, of course, asked where we were going... "You're gonna' go for a ride like you've never been before and will never go again!" We then proceeded to the proving grounds at the factory where a bunch of Army Brass and other dignitaries were assembled around the final Snow Train (as we called it). He hoisted me up in the cab and took off "once around the park"... 8 years later I spent my summer testing the world's largest front-end loader that you referenced in this amazing video. My heartfelt gratitude to you for these amazing memories...

My dad worked for RG in the early 60s. We even lived in one of his Quonset huts (ex WWII hospital) in Longview. My dad was a diesel mechanic and worked on the scrapers building Stemmons Freeway in Dallas and the tree crusher. He told me about the land trains, but he was assigned to other projects. When a company leased equipment from RG, the lease came with a dedicated mechanic and that is what my dad did. The unique aspect to his work was having to possess a combination of mechanical and electrical skills due to the unique combo of diesel powered electrical wheel motors. I am going over today and play this for him. Cheers from Texas.

Thank you for honoring Mr. LeTourneau. One other thing of interest is that he wasn’t getting the quality of engineers he wanted, so he started his own engineering school. LeTourneau University is highly regarded as one of the premier engineering schools in the country. There is a museum at the university in Longview that is amazing to tour.

Yeah such an amazing idea "I cant find good welders so I'll make a school to train my own!". Love it.

I am attending letourneau now. Not for engineering (been there, done that) but for professional flight. He loved his airplanes. He got in to a car crash and after that, he flew everywhere. He said it was the safest way to travel. He used to use a converted ww2 bomber as his business aircraft! Letourneau offers several aviation degree programs. All include getting your A&P license(airplane mechanic), including mine which is a concentration in aviation management. (You get your commercial pilots license, and A&P license along with management and aviation law classes)

[@joebledsoe257]

Used to work for the Letourneau rebuild Facility. They had some interesting ways of doing stuff. In his day they made their own steel as RG couldn't find what he needed to make what he wanted the way he wanted to. He even made his own bolts. He had a 3/8 fine thread double lead screw. It looked just like a 3/8 NF thread bolt but a bolt of the same size would not fit it. A 3/8 NF tap would match up with the threads on the bolt but the bolt would not thread into a hole tapped with it. Think of a bolt that had one thread started at 0 degrees of the bolts circumference and then another thread that started at 180 degrees. yes 2 different threads at 180 degrees apart. Rebuilt so many different things there. He designed and built his own motors and generators, both DC and AC. all of the components. They did all of their machining work in house. You got it all right, spot on, and correct as best as I can remember.

[@CalumRaasay]

Thanks for that comment Joe, what a facinating place to work that must have been. I find it really interesting how much was done in house - explains why they were able to fabricate so quickly and easily as they had access to everything on site.

[@danhammond8406]

3/8 double entry threads. On the large pumps I deal with they use acme type double entry threads. Those use 6 inch shafts tho

[@raywagner8016]

I kept one of these 1/2" bolts as a souvenir from a C9 Wheel Motor. I've drug it out many times in the last 20 years to show Engineers what Engineering looks like.

[@dashlamb9318]

I don't think I will ever understand the 3/8 bolt explanation. But I'm sure you are right about it. I only had the pleasure of running some of the scrappers and dozers when around 1971 going through my union apprenticeship program.

[@kshrock]

What's the point of a double entry thread? Do they screw in faster because they have to be a higher pitch but they hold just as much as a standard fine thread because there's that many threads per square inch?

[@tomhoward1996]

One amazing feature of RG was his refusal to let others stop him. His designs required very thick steel plates, but his total purchases were small compared to other users, so he had low priority to get deliveries. His solution was to build his own steel mill. He built an electric arc furnace for melting, bought molds to cast ingots, and made a 10 foot wide rolling mill to produce the plates. I got to visit the plant in 2010 ( a rare event) for a job interview. Coming from major steel plants the shop looked a little jury-rigged to me, but it WORKED! It even had a vacuum degasser, which produced some of the highest quality plate in the world for very demanding end uses. A remarkable man.

[@edwardfletcher7790]

I can easily imagine something like this being built as a mobile Mars base. It makes a lot of sense given the flat ground and the need to avoid year long dust storms that would cause incredible problems for a stationary base. But of course the size & weight of it makes getting it into space an impossibility !

[@diGritz1]

Sounds interesting but it would be a tough sell with our current level of tech. Mars regolith is incredibly damaging to mechanical surfaces. Opportunity drove roughly 28 miles before DOA. It had a wheel, probably bearing, failure around half that. As weight increases so too does the damage regolith can do to mechanical surfaces. This means any vehicles will need to be small and relatively light. Probably 3 to 4 people max capacity. It will also need to be small enough to fit inside a shelter for maintenance and protection from dust storms because they can cover the entire planet. This limits the type of vehicle to short excursions. It's no joke to say it's quicker to walk then drive. No matter what the movie "The Martian" would have you believe.

[@edwardfletcher7790]

@@diGritz1 You make some really good points. I wondered why the wheels got so trashed and attributed it to an overly enthusiastic weight saving protocol Vs incredibly sharp Martian rocks. Also the vastly over extended mission duration. Your point about Martian dust Vs wheel bearings is also a really good point. Someone is going to have to develop a grade of grease that can handle Martian conditions.

[@capitalinventor4823]

@@diGritz1 Spirit and Opportunity rovers were planned to operate for 90 sol days (just less than 92.5 Earth days) on Mars. After five (Earth) years and three months it was Spirit that got stuck in some soft sand and could not get out. It had travelled 7.73 km (4.8 miles). Opportunity travelled 45 km (28 miles) in almost 14 and a half (Earth) years when it went into hibernation mode for a dust storm and did not wake up after. The rovers were over-engineered for their original 90 sol day mission and had no servicing while on Mars. It is amazing that they lasted for as long as they did in such an extreme environment considering all of the dust that may get into moving parts. If there were a base, or a vehicle, with people on Mars (or any similar place such as the Moon) then it will be engineered to carry the load properly and to be maintained, or fixable at the very least. I don't know where you get the idea that walking will be faster than riding a vehicle but even if one to assume that it was correct there are still disadvantages. A vehicle offers extra protection from the environment, it doesn't tire the person out, and it allows far more good to be carried with oneself.

[@davidelliott5843]

Mars dust is toxic and incredibly abrasive. Dust storms can envelop the whole planet so the only safe option is to wait them out under cover, probably underground. That will require energy systems that don't need solar or wind power. Nuclear is the only option. Probably molten salt as it's (relatively) light weight and intrinsically safe.

About 100 guys in the main site down in the valley and 6 of us up on the mountain with the radar set. Don't think that they would have built it with road train. So much difficult terrain. We were right on the water so they probably brought the materials in by barge (when the sea melted in summer!). While there, that was the way we got the years supply of bulk goods.

Calum, I'm a 62 year old former professional diver, ironically from Yuma, AZ. Late '60's- early '70's there was a large Mil. Surplus yard on the outskirts of town called "Jet Sales". There the MK2 Command Cab with several trailers connected sat for years. As kids we loved that place. Rode our bikes for miles in the heat of summer just to look through the fence. Sometimes the owner let us in & allowed (tolerated) us exploring. Raised on everything from John Wayne to Godzilla, & Tonka Trucks, we were always drawn with awe to the "Land Train". He'd let us play around on it but would never allow us inside. God forbid! Also nice to see a Nikonos V on your shelf. Thanks for the blast from the past! Subscribed! PS: Some of those same friends riding bikes with me are still employed at YPG running departments now, soon to retire.

What an interesting Video. I must say, I am surprised how well these huge vehicles like the Land Trains or Kharkovchanka worked yet they never managed to take off because they were just in this very niche market. Thank you for documenting these peculiar vehicles, it's hard to find well made documentaries about obscure vehicles I always thought only existed as concept art. Keep up the good work!

longer that about 100+ft for simi's aren't realistically legal on I80 ect as the laws are written in 2019 as this road train is. it might not help that the usa 🇺🇸 government in the 40's-90's was super paranoid about sharing technology like this equipment designs and may have stunted the civilian/other market for things like this. and at the time being so big vs what normal freight companies need or used in 1970 aka a little to big 7-car vs 3ish-car long, may work better in-today's market place as the need for moving more freight with less labour and quicker/cheaper is more so appetising than in 1970

Fascinating, to say the least. I was in the U.S. Air Force and stationed at Eielson AFB in Alaska in the late '70s. There was a DOD disposal yard not far outside Fairbanks. In that yard was a lot of pieces of one of those trains and that included the power unit and it was a skinny one that sat down between the tires. It was very interesting to see such a machine. I had never seen tires that big before. I wonder if that's where Big Foot got his wheels and/or tires. Everything in that disposal yard was for sale. FYI, Tok, Alaska is pronounced with a long "o". I believe that LeTourneau is now owned by Joy Global which is owned by Komatsu.

I was stationed at Ft Wainwright 2006-2011. The LCC-1 sno train parts were in that same junkyard outside of the back gate until 2011. I tried to contact the owner with no success so I called the real estate company when it was being cleared and asked to enter and take some photos. Unfortunately the gent I talked to denied my request, the owner perceived too much risk. The LCC-1 and parts disappeared soon after, I thought it was scrapped. I didn’t find out until later that it went to a museum. Thankfully it was saved. As of 2011 there was still a land train trailer in Tok in addition to the land train power unit and a couple of cars between Fairbanks and Fox.

Hi Calum, I enjoyed every second of your documentary! That's a lot of effort you put into it, not only the research and the level of detail - but also the presentation is made very well. Thank you very much. An addition: RG LeTourneau once stated (I think in one of his Now! magazines) that most of his money from selling his business to Westinghouse was spent up for basic research to make powerful electric motors compact enough to fit into a wheel. The mayor brakethrough came when they started to use fiber glass as an electric insulator in the motors.

[@CalumRaasay]

What a fascinating piece of info! Thanks for that, and thanks for watching!

[@glennglover5675]

Hi everyone- This account of a great man is amazing as he is one of my personal life time hero’s. I knew of his work with electric motors from his experiences with electric motors in the US Navy and early earth movers using tractors and electric control of a pull behind grader in road construction. Thank you for your extraordinary work on some of his other projects. When he sold his parents to Westinghouse he went into the forest industry and also the invention of self floating and self lifting off shore oil rigs. The legs were cranked down using large electric motors-of course🧐 thanks again!

[@CalumRaasay]

Great comment! An amazing guy, I have in fact seen at least one LeTourneau device - the self jacking rigs have found themselves in Scotland a few times!

Oh, wow! This is SO CLOSE to that one weird and cool arctic vehicle I was trying to tell you about a (long) while ago. Just imagine this with wider and treadless wheels and with only one trailer (which also has the same big cushy tires). Every once in a while I try to find out what TV program I saw it on. It was a Discovery show, I think. (sigh) I'll keep looking... 😉

[@CalumRaasay]

Haha don’t worry I’ve a long list of things still to get through!

[@popuptoaster]

You are talking about the Antarctic Snow cruiser, it was pretty terrible but looked awesome, the Russians built a more successful tracked vehicle for a similar purpose. One of the Big-Foot monster trucks used surplus tyres from the snow cruiser.

[@CybershamanX]

@@popuptoaster The show was about these monster vehicles that hauled immensely heavy loads, like tanks of aviation fuel, across the ice. They were high tech. The cabs were big and heated so the driver could be comfortable for long journeys. They would have two vehicles for each trip with one basically being a support vehicle just in case one broke down along the way. They had built in cranes for changing the big wide tires if they had to. They had multiple sets to support the giant loads. They looked like something from a scifi movie. I'll find it someday... 😉

It took me a while to work out what the Land Trains' aesthetic reminded me of, but I finally pinned it down: they're like something out of the second series of Tom Swift books, the ones written in the 1950s and '60s and starring the son of the original 1910 character. If they had ever actually built the nuclear-powered one, it would be _exactly_ a Tom Swift Jr. creation. _Tom Swift and his Atomic Land Train_ would absolutely have been a title in that series. Hell, the whole Arctic convoy thing wouldn't be at all out of place as a Tom Swift Jr. storyline, except that in addition to the elements, Boris-and-Natasha-style Communist agents would have been trying to stop them the whole way. :)

Great video! I'm lucky enough to have seen the still mostly intact TC-497 Overland Train Mark II back in the 1970s in Yuma. My dad worked for Bell Helicopter and often went to Yuma on business. On one trip he took my brother and I to a scrap yard where the Mark II sat waiting an uncertain fate. I say "mostly intact" in that the train was along an outside fence and ran the entire length of the yard! Except, that was only half of it! They'd seperated it in the middle and it ran the length of the yard TWICE! Just an unbelievable thing to see, especially when you weren't expecting it!

Incredible! Fascinating history. The dry/gross weight ratio is interesting on these machines. I'm sure with more design and prototyping they'd be able to reduce the dry weight. But a 2/3 ratio is laughably miniscule compared to tracked trains.

I worked on his Marine 100 tons cranes when I was a Q.M.E.D. engine crane maintenance aboard the SS SeaTrain Florida and etc for the Hudson Waterways Steam Ships division of Chase Manhattan Bank PK lines (Sam Kahn and Howard Pack). The 1-- tone trains were using the electric wheel principle to power the BOOM, Swing, Main HOOK and Aux Hook lifts. The 2 cranes could load locomotives and 100 cars of a railroad train unto the ship and tie it down.. We haul War Supplies during the Vietnam War from Helicopters to Beer. C-ration to Ammo, Tanks and Trucks, and what ever they wanted to load. These cranes were Letourneau built and used a Wheatstone bridge control hand to excite the series of generators to controls the motors. A 7 year old could operate the crane.

These designs date back to a time when it was apparently believed that driving a wood factory into the middle of a forest and cutting down the whole thing was a good idea. It's definitely a good thing for both the inventor and Mother Nature that the logging train wasn't put into production, but it's still kind of cool that he actually built a prototype of it.

[@JurisKankalis]

The "preserve the nature by all means imaginable" aspect of nowadays is often exaggerated, piloted by people who somehow gain much traction and who are somehow overly loud (become very much visible with loads of followers) on media and of course the internet, without realising that even such "traction" and exaggerated fanatical approach tends to be destructional, including for nature - most often such attitude seems to be advocating not the nature, but their own agenda and over-swollen "face". One very topical example is the EV craze where an industry which is globally encompassing (been in place for more than a century) and is becoming gradually cleaner and cleaner will have to be re-invented, re-done, re-manufactured, re-industrialized, re-standardized and re- everything - with very often much more harm done than the magical "saving the earth" which the panda, penguin and polar-bear lovers see in their slightly zombified minds. One specific example is digging for lithium (not mentioning thousands of other spheres which will have to be completely re-done in all fields imaginable) - if one sees how we've been engaging in extracting minerals so far, been to some of the oldest old-fields - imagine a new mineral (lithium) now coming into play - many pristine territories, even countries will be dug up - just because the EPA (propogated by the green-glassed penguin people) and the appropriate EU institutions have said "no more ICE-cars until 2030". So while I'm categorically against throwing your crap and waste around you without regard, I don't think "ooooooh, mother earth will revenge and rise against us, I need to hug some trees" and similar attitudes can be based on anything serious - apart from serious mental issues.

[@Js-rq9uj]

@@JurisKankalis you’re right on about lithium especially and most “save the planet” people not having a clue about the actual cost of what they believe to be saving the planet…organic vegan food comes to mind, grown with bone and blood meal from slaughterhouse floors 😂. That said, I think it’s in inescapable reality that our natural resources are limited and there is need for better engineering…there are some 3 billion plus more people in the world than when I was born, and every one of them wants cell phones and cars with rare earth minerals, pure silica, etc. I am a firm believer in the conservation of specific wilderness areas that preserve our nation’s (I’m American) patrimony. Basically I agree with you that most people are clueless bout the actual cost of what “clean” stuff they are buying, and that they are just buying into the marketing, but I think there is an inescapable reality behind the need to find better ways to do things. Logging is a great example. It used to be thought clear cutting was they way to go, most efficient, greatest margins. But the logging companies themselves found in the longer run that they were depleting their own future resources, losing all the old growth and growing skinny, pathetic monoculture trees in their place. So they’ve had to shift tactics.
