Rotary Dumper Crushes Coal Car - Caught on Camera
Вставка
- Опубліковано 28 тра 2020
- With new designs and customized models, it's not uncommon to find bugs and issues along the way. In this case, we found one! The IR detectors did not sense the coal car, which was incorrectly positioned prior to the dump (my fault). Thanks to Grayson, a new version of the software controlling the dumper has been installed and this will no longer happen. And thankfully, no major damage was done to the coal car or to the rotary dumper.
Thanks for watching!

You reached peak modeling when accidents are realistic
OSHA investigation and fines coming. No new layout additions until this is straightened out.
ChrisBalthis : Would it be an FRA investigation?
Should be just OSHA since the paper mill is not railroad property
Going to take more than a hammer and some suction cups to “straighten out” that wagon!
Not to mention NTSB and FRA as well. I hope nobody was injured in the accident.
Lol
Actually that makes it more realistic. Put a sign up that says
This plant has worked
?????
Days without an accident
Hahaha I like that idea
Good idea
Oh yeah like in the Simpsons lol
Reminds me of the old show “I Love Toy Trains” where the guy is like “Oh no!” as trains crash or something happens on the layout
oh yesss i remember that i used to watch that
Yeah!
Haha yes, youre totally right. Shoulve put those sound clips over the video!
@@nsmodeler24 Not too late to do so.
oh yeah!
opps drug test for everyone. LOL
lol
Now stick the car on a stub track some place with a shop tag on it. Conversation starter and a nice piece of scenery.
Haha I like the idea! - Josh
@@nsmodeler24 Josh time to cut a new piece of Aluminum and slap it on that car in the Car shop and get it back out making the Road money.......
Actually I don’t think they could fix that, it would be spray painted with “SCRAP” or something.
Uh oh, time to buy a new one!
You'd better believe the FRA will be out for an investigation for this
and with the FRA the Kids on that Crew gets a 30 day Vacation pending the Investigation
This is great! I worked unoading coal with a rotary. The real one also uses sensors and logic to make sure this doesn't happen, but i assure you, it does. I had to clean up a few messes from the logic getting confused or dirty sensors causing issues.
So I'm guessing a kill switch or E stop will be an addition to revision 3 firmware?
Funny story about finding software glitches... we set a 1000hp 4160V motor controller on fire we were designing once, when we discovered we didn't have a 'latch' for the main contactor in the software while the unit was running. Once we started putting the unit under load, the system saw the bus voltage drop which was normal, but instead of staying in, it reverted back to the precharging mode thinking it wasn't fully charged anymore. with a 6200V DC bus, your contactor options are limited so we used an AC vacuum contactor... for those of you with electrical knowledge, I'll remind you that you cannot break a DC circuit with an AC device... so when it tried to open the circuit that was under full load, it opened the contacts, but the DC jumped the gap, kicking off a ton of x-Rays, and heat, and in a few seconds time, turned the metal and ceramic vacuum containment bottles red hot. The plastic didn't like that and so it caught fire. Extra bonus the unit is air cooled. so it's sucking 15,000 CFM of cooling air, and now smoke through it, filling the lab area with beautiful white smoke. This catches the attention of building manager, and he comes running in with a 20 pound dry chemical fire extinguisher... 3 engineers tackle him before he squeezes the trigger, which would have destroyed 3 years and about $90,000 worth of equipment! Once the main power was shut off, which it was seconds after this was recognized, the heat went away, and everything settled down.
Funny how one little glitch can cause so much havoc.
For reference, you NEVER want to shoot dry chemical at any electrical equipment that's on fire unless there's a life safety issue involved. Use CO2, Nitrogen, or Halon (the best actually, but expensive). Dry chemical will absolutely destroy anything electrical once the slightest amount of moisture gets to the powder sitting in the equipment. You may as well throw it out at that point. That's why computer rooms, and other sensitive electronics have Halon flood, or N2/CO2 systems. It puts the fire out, but doesn't destroy everything else in the room with it.
Hi Josh. Did you file a claim with the insurance company? Ha!! Lol. Enjoy the day. Ray L
Don’t mess with that coal car. Just leave it as is because it looks better
It's staying as-is!
Yard foreman: "... Go get shovels. Now."
Well that’s no good! Bet it was a pain to clean up. The top “gone” graffiti is very funny. If that was real life, somebody would be fired LOL
"PTC could've prevented this"
It was hilarious when you realized what was wrong
You get a whizz quiz, YOU get a whizz quiz, everyone gets a whizz quiz!
"TOP GONE" XD
One of those "Happy Accidents." Prototype like damage though. Glad you bleeped-out the dialogue; keep it PG.
Haha thanks Colin!
went to the old fort loops for the first time today and it was crazy how I could recognize parts of your layout on them
George Carlin (as Mr. Conductor): Luckily, nobody was hurt, but the coal car was bent in half. Sir Topham Hatt was cross!
Thanks for not hiding this. Hehe. It makes me feel a lot better about when things have gone wrong on my layout.
That's awesome, at least the car still runs even though it got damaged, but I'm sure something like that has happened in real life before, machines don't always work 100%. Nice video!
dumper: rmmmm crack. crazy cursing
Well, at least no railroaders were injured in this instance.
At some point I need to see your layout in person cause it's just too damn cool
You guys knocked it outa the park with this set up
We know what someone is going to get in their stocking this Christmas :)
That is a realistic accident. We have actually been called to pull a car that was caught by the rotary mechanism. Wish I could have taken a picture but on Power Plant property we were being watched very closely.
@@jwalker7567 It would be similar to taking a soda can and holding each end and twisting. We moved the car off to the side and it was later scrapped onsite.
Would've loved to see it!
That is some awesome looking weathering on that car now
Haha thanks!
gasp, that poor coal car
The prototypes have wrought similar damage on hopper cars, and even locomotives that were incorrectly coupled to non-rotating couplers, the result being they were spun right off the rails.
Nice improvision with the "top gone" hopper
That was grayson's idea! haha
Nice
Almost video as always you and your dad have an absolutely awesome NS layout
Awesome layout
@@ronstrainsandmore Thanks Ron!
Josh....you never seem to amaze me.....NICE...!!!!....IN A GOOD WAY.....YOU....MY FRIEND HAVE A REAL RAILROAD THERE......👍🚂
Thanks Val! Means a lot. - Josh
not looking forward to that phone call and safety meeting :) uggg. Glad your dumper didn't suffer any heavy damage
Haha we are too. Thanks Matt! - Josh
You made it look realistic with the car bending in the accident! Lol and the scratch mark is realistic!
That’s awesome!!! Love your layout!
Good stuff! Unfortunate but glad you shared. Thanks!
Has to be one of the absolute coolest model railroad videos of all time...
Thanks man! Means a lot! - Josh
As an engineer that delivers to a plant with a rotary dumper, you should have left all that coal where it landed. The insides of a shed like that is black with dust and spilled coal. Sweet model though. Good work
Ooooopppsssss, Well I guess that car now features the most realistic weathering and distress on the whole fleet, actual real life distress......................cool! Best regards Dave.
Thanks Dave!
Coal car gets crushed by rotary dumper
OSHA: "You get a Whizz Quizz! You get a Whizz Quizz! EVERYONE GETS A WHIZZ QUIZZ!!!
FRA/NTSB: How did that happen!?!
Crew & management: well, ****
Maintenance Department: IRONY TIME!!!! XD
now you have a car to stage in your repair yard:) so glad to see your working on a video of your coal operations, cant' wait :) #caolloader :)
Thanks!
When I first opened the video I thought it was talking about a real train and was hoping to see some real carnage. When I realized how long it took me to figure out this was a model and not a real train, I was not disappointed lol.
Great video!
Insurance won't be happy about that one 😂
NS Modelers mouth: Ah “””” “”””
Me: LOL
Not what I expected but probably more interesting!
Any chance ya are going to sale plans on how to build one of these a simple one lol. Thanks love your videos
Oh my! Im sorry that happened
That car shall be remembered as the “Top Gone Crushed” car
better get O.S.H.A and safety crew out there
Will there be a class on model railroading accidents?
OH NOOO!!!!! clean up on track 3, clean up on track 3. "TOP GONE" funny😂 . be safe and careful around the rotary dumper
Haha and watch out for flying coal!
Cool setup!
Thanks! - Josh
Josh Sorry that you had an accident at the Dumper. I think that the Crew of that train that was on that shift that day should get 30 days off Pending an Investigation. Well that is what the Real NS would probably do to the poor crew......... But as we say stuff happens...... :)
Interesting & Cool 😎 • Cheers from The Detroit & Mackinac Railway 🚂
Josh, I can relate, back in the late 80s early 90s at the Ohio State Fairgrounds large NMRA Division 6 layout a buddy of mine had 80-90 unit train of Wisconsin Electric high side gondolas and was running live loads and helpers. Now remember this was prior to DCC with just powered blocks. The layout would support 2-3 long trains in each direction on the doubletrack. The dispatcher accidently killed power to a block that the head end power had gone through and forgot about the helpers, well it pulled the entire train over on its side spilling coal everywhere on both mains, during the State fair none the less. We must have looked like real professionals out there with a shop vac cleaning up coal and rerailing a unit train. LOL
@1:58 When recording this you should of showed a worker down there with a shovel cleaning up the coal. 😃
Thank goodness the dumper is OK. I thought it was destroyed before I viewed the video.
We thought that too at first! Gladly it is fine.
Awesome video. I'm so glad you are keeping the damaged car. *%#$ happens in the real world so it's nice to see you model that too !!!
Haha thanks Paul!
Like a real mishap. I'd leave all the coal too. As someone pointed out below, even the mishaps look real.
Fantastic fun lol.
Very real problems! Love the battle scarred look of the wagon too.
At least there was no major or unrepairable damage to either piece of equipment. Have given any thought to using a basic sound decoder and using real rotary dumper, just coal pouring sounds or even industrial warning sirens?
Great idea. Since this is a on going engineering project, we (obviously) have a few things a bit up the list from that, ... but at least it is now on the list! 🥴
Sorry for your 'loss' there 😁 At least the car has been able to be retrieved and put back to use. Will you explain in a future video why the software went out of whack and needed an upgrade?
The software at first just sensed the car going by but if, as I did, go by and bounce back out it wasn't programed for that because we never considered that possibility. Now it senses clear or in position before the rotating motor is allowed to start it turning. Live and learn. Live and learn!
Nice video! Unfortunate accident, kinda crazy! Nice way to fix it!
Well, just like the real railroad, you never know what may happen.
This video has recommended to me and I watched most of it not realising that it's not an actual train but a scale model until I saw the publisher's name.
AWESOME GOOD VIDEO VERY INTERESTING AND INFORMATIVE THANK YOU.
Love the working dumper. Have you guys considered a "kickback trestle" after the dumper? That would remove the need to pull the empty cars back though the rotary dumper, and should streamline unloading trains. They existed to fulfill the same issue on the prototype that you guys have in your layout, not enough space for unloaded cars directly after the dumper.
And believe or not, we did consider that very thing and we still didn't have enough room for that. Thus we ended up with what we have.
I hope your RR is investigating the engineering failure that led to this disaster. Hopefully, no scale people were injured in the mishap. As my uncle used to tell my (Purdue-educated) father "They oughtta fire half the engineers and send the rest back to Purdue! At least your cleanup was much easier than the prototype effort.
Seriously, nice video, and nice job on the dumper scene and mechanism. What does the IR scanner detect when determining that a car is present in the dumper? Does a car in the dumper present a different heat signature than when the dumper is empty?
The I.R. sensor only senses if a beam is interrupted. Originally it just looked to be blocked and then clear. The new program now won't allow any rotation if the sensor is blocked at all. Much better because really light cars might bounce back out partially, which I believe is what happened.
Live and learn! 😉
Now you have a hopper car with real damage done to it!
I’d like to see a triple crown roadrailer train on your layout or an old NW southern NS mixed locomotives long coal drag running would be awesome
Would love to see that too! unfortunately we don't have that equipment!
NSmodeler24 I’ve got a set of NS Triple Crown roadrailers with a ring engineering End of train device I’d trade for a locomotive freight cars or I’d sale em if your interested
Those things happen. It looks like the real thing. Good work.
I’ll wait until the USCSB UA-cam channel puts out an animated reconstruction of the accident...
Please! Can you explain how you do your photography? I have been into model railroading for more time than I care to admit but watching your channel I sometimes have a very hard time figuring out is it the prototype or is it model railroading as your images look so real, so close to the real thing.
Everything is filmed with my Iphone 10. I like filming with a phone, because it allows you to get close to (model) ground level, which makes the shots looks more realistic!
OUCH 😣....looks like operator fell asleep 😴
Sorry to hear about the misfortune of what happened. Out of curiosity, what change does the new program put in place? Is there a way to set a force limit on the dumper similar to how a garage door operates, so that it returns to 0 position should it encounter an unexpected force, be it a car not fully in the dumper, a misplaced finger while it is running, a pet, or coal jammed in the gear set? Additionally, what about an emergency stop button on the fascia that aborts the process and shuts down the dumper for a set timeout, call it 2 - 5 minutes, gives crew time to remove and reset car if need be, and sweep up. Recess the button in the fascia so there aren't accidental stoppages. Keep up the excellent work on both the layout and your video content!
I am a big fan, your layout is amazing, museum quality. Do you have a track plan drawing? I'd love to see the whole layout!
Also, the link in your about page is broken.
The updated program monitors the IR beam sensors throughout the entirety of the cycle. If any of them are broken the dumper immediately stops rotating. It also won't even start a cycle if one of the sensors is blocked.
Thanks for the explanation Grayson!
@@GTI6speed Excellent, thank you for the info!
I love how the damage looks real
Ah yes, premium tier clickbait.
So you now have a quite convincingly damaged coal gon....
Haha we do... Thanks! - Josh
This reminds me of Thomas and freinds. Because one time in the older shows Percy number 6 green engine was lifted into the coal hopper loader and got his coal drop out. Oh the memories. XD
By chance do you remember what episode it was? It'd be interesting to see that scene. In real life such a mistake would be a very serious accident, with a risk of severely damaging the boiler from the hot fire as well as the grate bars being dumped from their normal position onto the arch and crown sheet. Plus all the appliances would be slugged with water instead of steam, injuring them too. Poor Percy would be in the workshop for a month getting a full inspection with repairs.
i repair these cars, that's how i ended up here. now i know what "dumper damage" looks like. great work on the model. That's my job security
I wonder if this has happened to real trains....also I would have left the spilled coal for extra scenery, If it didn't interfere with operations of the coal dump. Your right the coal car looks more realistic now!
Wow, imagine the insurance deductible.
was he trying to push the car in with his finger just before the dumper started to rotate?
He was actually trying to pull it out.🥴
"This" is why Rotary-Couplers were invented. Keep your unit-trains whole and dump at the same time. You just need one per car.
That means we need about a hundred or more rotary couplers!
many machines such as lathes have sacrificial gears that will break so nothing else gets damaged - they are an engineered “weak link” for when the software/sensors/control fail.
I saw your hand Deliberately Overriding the Mechanism .
Actually, it was his hand trying to pull it out before it got wedged in the dumper!
If you could be a locomotive for one day, what kind of NS locomotive would you want to be? Also, would you like to voice in my series?
We don't make mistakes we make happy accidents
Bob Ross
Haha well said
Here today, gone tomorrow..lol great vid.
Where does the coal go and how do you get it back
That's one strong rotary dumper!!
That's a real world battle scar to be proud of IMO. A true story!
Boy you really go to extremes for realism!
Wasn't exactly intentional, but it sure looked real!
NTSB Needs to see this.
The best way to handle events like this is to just roll with it!!
Accidents happen now and again! Sometimes just by chance!
