The Consolidation could be the standard US Army design of WWII. There were at least 42 railway-associated battalions in the Transportation Corps in WWII (I have a book that tells me this), 39 of which were railway operating battalions. Each battalion was associated with a particular railroad, presumably built around a cadre of experienced personnel from that line.

Which was also assisted by the local railroad, the Red River and Gulf, which is still slightly preserved in the near by Southern Forest Heritage Museum in Long Leaf Louisiana. Most of the artifacts found in Camp Claiborne is found here at the SFHM. There is essentially nothing left from Camp Claiborne, aside from a few concrete roads, and foundation.

@@sambrown6426 No, it doesn't look British at all. I guess there are some similarities with a small tank locomotive like the LB&SCR E2 class (on which Thomas the Tank Engine was based) but British mainline steam locomotives never looked like this. In particular, we didn't have any 2-8-0s until 1903. Remember, the British loading gauge is much smaller than the US. We don't have room for those tall chimneys and steam domes, except on early or branch line designs, as it was a challenge to fit stuff within the loading gauge. If you think about something like the Big Boys, which were also trying to fit as much steam locomotive within the loading gauge as possible, you get the top of the boiler at about the same level as the top of the cab, and a very squat chimney and steam dome. Same in the UK, just on a smaller scale -- something like an LMS Stanier Class 5 ("Black Five") is very typical of 20th century British design and is a very compact locomotive that uses most of the available volume.

Thermite and a wood mold to cast a derail into the track out of the produced iron seems a much better bet than explosives. Or some easily transported method to BEND the rails into a derail profile, and then spiking it so that the train doesn't simply unbend it.

[@88porpoise]

The thing is, that all takes specialized knowledge and tools and resources. Some random GIs or local insurgent group are already going to have access to explosives and the training to use it for all kinds of purposes

[@beeble2003]

@@88porpoise Exactly. They were looking for techniques where one guy could jump out of a bush, blow up the track and run away within a couple of minutes, using stuff that could be carried in a backpack. Carrying a bunch of explosives lets them sabotage whatever target of opportunity they come across. Using thermite and moulds and stuff means they can only sabotage railways. Plus thermite requires a large, heavy container to hold the reaction as it progresses.

[@Knsgf]

Reminds me of Englewood Railway accident, where a string of log cars broke loose on an incline, got knocked off a track by a derail, then managed to rerail itself at the switch after the derail and rolled downhill unrestrained, eventually slamming into a parked speeder.

It didn't phase that train one bit but I learned a valuable lesson. Get away...

[@Nderak]

2:06 one of the big lessons we learned from WW2 was the need to practice in minute detail any and every little bit of tactics and warfare. in the last big war games before the conflict began one of the changes was going from simulating things on paper (company 5 stopped and check their transmission oil) to doing it IRL where they found it took much longer and then could be done differently to improve many processes.

[@onnelli]

Surprisingly, not a lot of Kenosha in this one!

[@MegaLokopo]

If they played the right music maybe the train would have crashed sooner.

[@mfbfreak]

I guess you need to blow a hole in the track, and then hammer one of the rails towards the centre of the track, so it catches the flange on the wrong side.

[@SVSportscars]

My thought exactly, that should work, might be hard to do. but it should make sure it derails.

[@beeble2003]

Right but that requires carrying heavy tools. If you could do it just by blowing out some track, you just need a few handfulls of plastic explosive. Also, you can't just hammer a rail to one side: they're effectively a big spring and will just straighten up again. You'd need to lever it to one side and fix it in position, which is going to require a gang of at least half a dozen men with long crowbars and hammers.

[@malcolmmackenzie9202]

I remember you talking about this a while ago with kan. It's very interesting how much a train can take and stay on the rails.

[@oriontaylor]

Another film you might consider a reaction video for was called ‘The Mole,’ also OSS from the same period (and is on the Charlie Dean Archives YT channel). It’s about a nifty photoelectric sensor attached to an explosive with the intent of causing derailments in tunnels. I’d love to know if they ever made it into service before the war ended.

[@Sigil_Firebrand]

I remember seeing War Trains at my local navy museum, with the director and narrator there. I have a signed VHS set somewhere at home. This was always one of my favourite segments of Subvert and Destroy. As an edit: War Trains was a 3 part series, and you can still get it on DVD, I can't recommend it more, so many interesting videos like this one are in it.

[@heronimousbrapson863]

Maybe this is why the saboteurs of the kwai river line in WW II blew up the bridge?

[@davidty2006]

turns out turning bridge into canyon for the train is alot easier than trying to throw it into the dirt...

[@beeble2003]

Note that the film _Bridge on the River Kwai_ is fictional. But, yes, if there's a lightly built that you can take down, that's going to be much more effective, because it takes much longer to rebuild a bridge than to re-lay some track. On the down side, it will take a lot more explosive to bring down a bridge than to blow out a section of rail and most European rail bridges would be built of stone or heavy steel, so would be a difficult target for a sabotage crew.

[@jimfisher7324]

Remember this OSS type stuff is limited in long term impact unless it is on a bridge and the crash destroys the bridge. An on tanker told me what the third army did. They had a big hook on the back of a tank. They would drive down the track with the hook ripping out the ties. A few miles of this and the railroad would be out of commission until some major work was done.

[@beeble2003]

Right, but this is aimed at one guy being able to cause significant disruption very cheaply with stuff he can carry in a backpack. Railroad ploughs can only be used on a railroad that you already control -- they're for scorched-earth-ing your retreat.

[@rgsrrofnc]

I'm sure I mentioned one of my derailments at Lakeside with the #18, about 3 decades ago on the 4th of July, the busiest day of the year. On the curve to come along Harlan, the rails spread. Since it was busy, we were running a little faster than we usually did (12 minutes per trip compared to the 15 normally.) The locomotive cleared but the front truck of the tender derailed. Luckily the coaches remained on the tracks. Water and coal bounced everywhere. All I could do is keep the train stretched as I rolled to a stop to prevent the A/V forces popping a coach truck off. When we brought the #17 up to hook on to my train to pull it back, she slowly walked across the bad track and as the rails spread, she slowly sunk down between the rails. The Master Mechanic was panicked and thought we would have to rerail her too. But I just had John horse her over and he backed her back up on the tracks. I mean it was the perfect rerailer there... So it's the momentum more than anything which overcomes the forces of bad track. The diesel arrived shortly after backing all the way around to where I was. And after walking the passengers back to the other train (#17's) they backed to the depot and we used lining bars and blocks and popped the #18's lead tender truck back on. The mechanics then drove additional spikes into the non-existent ties and they shut down steam for the rest of the day. I pointed out the diesel's trucks were gauged differently (1/4" wide) and would spread the rail more than the steam train's. So I spent the rest of the day sitting on my #18 keeping her warm and eventually, I watched fireworks off in the distance while sitting on the cab roof. The next day after working my paying job I stopped by to see that they dug out 30 feet of track and replaced the ties (poorly of course.) They also decided to swap out the rails. Not going with NEW rails but they swapped them around - by turning the individual rails around. These are rails which have been in that curve for half a century at least. They are curved. What happens when you turn a curved rail around? All the curve is at the joints (at the fish plates.) So they had an extremely superelevated outer rail (1" with 22" gauge) with all the curve bend at the joints. I would have to brace myself on the fireman's side with my feet on the engineer side to keep from sliding off. BAM. BAM. BAM. 3 hard lurches to the right at each fish plate. After this, I got away from doing much with the railroad (my friend John and I were actually working on the big tower there getting it repaired where 2 men with no budget, old ropes, and sheer bravery could.) The following year I was done, never returned to work there on the railroad again. They broke both steam locomotive frames and I think the diesel took damage too. A few years later I visited with my wife, my friend John and his wife and we rode the railroad and yep, that track was STILL trash. And to this day, steam is dead there. All because they had a moron master mechanic who didn't move the outer rail to the inside and the insider rail to the outside so they would remain curved the right direction and the other, unworn, side of the ball of the rail could be used. This is the same moron master mechanic who made a special track measuring device (took a day to make it) welded up nicely and all. It was a l-shaped device with rollers on the left side and a measuring "rod" across to the other rail. A long handle allows you to push it. He did this to spite me telling him the track is wide. You can see the tender truck hunt side to side so you KNOW it's wide. He said only a couple places were wide. I asked him where he measured to make his mark on his measuring stick that went across. He showed me where he put it on the tracks at the water tower and made a chalk mark. I pulled out my tape measure and measured. 23" OOPS. He just looked at it. Picked up his rod and left. Didn't say a word. Didn't fix the track either.

[@Hyce777]

Oh yowza. Yeah steam is still dead there. Too bad, really, it'd be so neat. They have more track than we do. Sounds like a real special basket case of a "master mechanic". Jeez.

[@warmstrong5612]

Knowing the kind of shoddy track that trains even today can run on, I'm not the least bit surprised that a gap in straight track means nothing to them.

[@kornaros96]

And nowadays locomotives have maximum 12 wheels. back then they could have 14 coupled

[@HATECELL]

How the explosives are applied can also make a large difference on the damage they do. I saw an old video from the Swiss army where they used hand grenades against rails. In the first test they just placed the grenade next to it, and barely anything happened. In the next test they tied it to the rail (it was a stick-shaped HG 43 for those wondering) with a bit of wire. This time they managed to blow the rail apart (although after seeing this video I doubt a train would've noticed)

Reminds me of some of the behind the scenes footage of the 2nd Zorro movie with Antonio Banderas. For the big climax of the movie with a runaway train full of nitroglycerin, the final scene was done with models as using the real deal they'd dressed up for the movie was a no-go for obvious reasons. Anywho, the special effects team lead for the scene said it was actually very difficult to get the train to derail like they wanted it to, hitting the earthen mound at the end of the track and rolling over into a big pile-up and explosion, touched off by the nitro blowing up from the jolt followed shortly thereafter by the boiler letting go. They specifically mentioned that steam locos are really good at keeping their center of gravity on the wheels, and they had to resort to using weights high up in the models to throw off their balance as well as a few other tricks, as for the first try or two the train just wanted to keep rolling straight in a line through the dirt upright after coming off the tracks instead of rolling over and accordioning together.

A partisan resistance operative would get exploding lump coal and a paint kit so they could make the exploding coal match the coal in the bunker(s) at the railroad.

I work on the UK railway and I would just need a Hammer to knock out the Pandrol Clips or if the Fast clips I would use a heel bar. take enough clips out and nothing is holding the Rail to the Sleeper train comes along the Rail gauge is forced to widen and the wheel drops into the 4 foot. You could mess around with the points and the signals.

I always learn more things about trains from you

[@Damien.D]

Should have asked us French. 60cm gauge trench railways were massively used in WWI, carrying ammo and troops on temporary badly laid tracks, and these things are close to impossible to derail. Some of the same kind of railways are still use in harsh condition in sugar cane plantations in indo pacific islands. The amount of abuse these systems can take is tremendous .They actually runs trains on straights with no rails at all.

Oh, my crew trainer showed us this in our new hire orientation!

USS Barb called. They sunk a train (technically)

If you havent read Thunder Below, it one of the best books writen on WW2 by the Barbs skipper.

I love watching these

[@neiloflongbeck5705]

Considering the diameter of the wheels, I wasn't surprised that a 12in gap had minimal effect at these speeds. As for the third test, the 36in gap, it goes to show just how little suspension a steam locomotive has built in to it and just how much the trackbed does to give a smooth ride.

That engineers got a pair, thats for sure.

I've said it before and I'll say it again, momentum is a hell of a drug.

[@Redshirt214]

Ah! I love this film!

[@stevemellin5806]

I've watched the film lots of times .It takes a big section of rail . great film

[@JeredtheShy]

I like the cheeky tone they take in the original film, but the way they delivered voiceover back then was so dry it's hard to tell he's yanking your chain, because he knows that train isn't going to derail.

[@magiccarpetmadeofsteel4564]

Tbh, I think the main takeaway a commando or someone else who’d sabotage a train would be to either do the rails on a curve, or if that’s not possible, rig the explosives to a pressure switch or the like. I’ve seen this video myself, and I was blown away by how hard it was to derail it. IIRC, I decided you’d be best off rigging the explosives to deform the track, instead of just removing it.

[@johndeere7245]

Just imagine being the grunt Army engineers that are having to go in and repair track and rerail cars after each attempt. I suspect by the 4th or 5th time replacing a track section they are probably thinking let this be artillery's problem.

[@donl1410]

Amazing! Thar cracked me up 🤣

Speaking of railway sabotage, might be worth looking at Ireland during the Irish Civil War (1922-24). A lot of derailments, sabotage and attacks on trains and railway infrastructure. Two that immediately spring to mind on straight track derailment, both in the same area of Killurin. One was on 15 August 1922, when two lengths of rail were removed just within a tunnel. A goods train exiting ran on another 30 meters before reaching soft ground and turning over, the coal wagons it was pulling piling up behind it. There's at least one photo during recovery, fairly impressive looking. The other was on 10 July 1922, when an engine managed to jump a three meter gap blown out of a bridge, brought its tender with it and came to rest about it's own length from the gap, at a right angle to the track and with the left leading drive wheel overhanging an embankment. The first wagon behind fell back first into the gap, but the coupling held, probably saving the engine going down the bank. This was this engines second major incident, and another would come before the war had ended! Some of the recovery efforts are also very interesting, as there seems to have not been any heavy recovery equipment available other than jacks. Lots of use of sleepers to make cribs, rafts etc!

[@ahzee4942]

Thats crazy and amazing

[@Captain_Char]

they say no steam but as that loco passes by at 3:50 look at the tree as the funnel passes it does look like its steaming slightly, unless its just artifacts in the video

[@mikeeuritt4396]

Sometimes back you had a video and discussion at the museum of how far a curve had drifted out of it original place. Even with that kink the locomotive stayed on the track. Makes you wonder what's going on with the mainline that they have disastrous derailment. I guess for safety sake we need to bring back steam 😂

[@hannahranga]

Speed and repetition generally, will it always derail no but 50 trains later it's less surprising when one does

[@nw611J]

This was awesome Mark you really don’t think ahoy it until you see it. By any chance do you know what areas base that film was made at?

[@Allan_aka_RocKITEman]

People doing this test must have had _loco motives._ 😉

[@44R0Ndin]

From my understanding of basic physics, the best time to blow up a section of rail to guarantee a derailment is when the heaviest part of the train is bearing down on the section of rail that has the explosives on it. That way you damage the most highly stressed part of the train AND the rail at the same time. The idea is that any damaged train prevents passage of any undamaged train, even if that undamaged train could have maybe made it over the damaged rail. Target the locomotive, AND the rail, at the same time. Or you know, just wait for a train to go by and poke a hole in the boiler with a Bazooka. Instantly disabled, even if it DOES stay on the tracks it ain't movin.

[@andrewreynolds4949]

Wrecking the track means it’s a lot harder to just push the wrecked train aside to get the line open. For best results, do it in a tunnel!

[@44R0Ndin]

@@andrewreynolds4949 Absolutely, but my whole point was "get the best bang for your buck by timing the rail demolition to the time when a train is passing over those rails", that way the enemy has to deal with a train that is more damaged than what would happen with just derailing it, due to the explosion that separated the rails. I do realize that at the end of my comment I kinda wandered off target, I tend to do that frequently because I have ADHD.

[@Pentium100MHz]

The problem is that you need to wait for the train and you may not know when it is coming. Oh, and you are behind enemy lines, so you may get discovered before you did any damage. So, blow the track up and get out. You may be able to cause a derailment or at least the enemy will have to repair the track. This also applies to resistance members in occupied territory - you probably do not want to spend too much time near the track.

[@44R0Ndin]

@@Pentium100MHz Right, I get that, I suppose that means you rig the charge so that it has a pressure sensor attached to the rails. These days it's pretty easy, just put an AT mine under the sleeper, but back in WWII you'd rig up the track so that the train passing sets off the charge. Automation solves the need to be present!

[@andrewreynolds4949]

@@44R0Ndin Of course! Battlefield or other conditions might not always permit that though, much like 'do it on a curve'. But blowing up a passing train as it enters a tunnel on a curve would be the dream

I love how weirdly normal the narrator sounds
