How Distributed Power Works

Here are some basics on Distributed Power. What it is and how it helps railroads move much longer trains.

[@shaunvalencia2644]

The KZbin algorithm brought me here and I felt the overwhelming need to let you, Distant Signal, know that this is on par if not a new standard for videos I watch on KZbin. The narrating, the edits and overall information were really great and made the video even better to watch. Really great job.

[@distantsignal]

Thanks Shaun. Those are kind words indeed and much appreciated. Glad the algorithm led you to my channel.

[@axelBr1]

For me, exactly the same situation (KZbin recommendation), and also wanted to say this is a fantastically put together video, and the narrator's voice is perfect. Really feels like a show produced by a large TV production house. Also, as a Brit, I've only seen trains like this once before when I was working in Houston, seriously impressive trains you guys have.

[@tbb236]

A note about NS’s use of DP from a current Norfolk Southern conductor in Birmingham: most of our trains are built by blocks. Cars are grouped in the train based on their destination. Most of the time when I’m doubling out of the yard and we have to place DP engines in the middle of the train, they go between certain blocks. On train 178 (Birmingham to Bellevue) we’ll place the DP locomotive between the Bellevue block and the Elkhart block. Upon yarding the train in Chattanooga, we’ll cut the Elkhart cars and the DP off, and shove the Bellevue cars into another track before going back and getting the DP off the Elkharts. The outbound crew will then swap onto the train and fill out in the class yard while 142 comes on duty and takes the Elkhart cars. Another thing worth mentioning is while the train lengths are increasing, as is the use of DP, it’s not all sunshine and rainbows. DP units can be very problematic in certain territory. Our run from Birmingham to Chattanooga on the AGS North has seen a major spike in train separations, especially on trains that run DP and trip optimizer. NS is looking into multiple DP sets now, but I feel that’ll only make things worse

I transitioned from truck driving after 25 years and 3 million miles due to health issues, and after several years being unable to work, I now transport railcrews to their trains and depots, sometimes assisting crews to build or separate trains, or go get equipment needed to get a train back to operational status. The longest I've assisted with was the night before last, a 16,800' coal bucket we split, so that one could proceed to the power plant downriver, and get the main cleared for other trains to continue their runs. It keeps me busy and able to work despite several physical disabilities. It's cool work.

[@paulsmith3820]

These are among the best railroad videos that I have seen. The producer knows when to comment and when not to. Equally important, he knows when to edit the presentation, i.e., cut away as opposed to showing every car in a train. In too many videos the producers don't seem to understand the importance of editing their presentation.

[@MBStylus]

Hello 29 year old here. i want to tell you to please continue putting the physics and mathematics behind the trains in your videos....... KZbin has become more dumber down in every videos content and i really was engaged in your presentation. it was like a professionally produced educational video.... i guess i felt like a kid again in science class is what im saying and i dont find that in most vids. was really engaged to your lesson. thank you!

A quick aside re: Origin of Distributed Power: My Dad worked for GE the 1960's as an Electrical Engineer. He had Radio experience from the USAF and held a First Class Radio Telephone license. In 1968 GE had an early stage project to design & control multiple GE train engines spaced throughout the length of the train (front, middle, rear) using radio control - I don't remember hearing the term "Distributed Power" (I was in High School at the time). My Dad was to be the leader of the project, but something happened and the project was put on "hold". My Dad was reassigned to work in Glens Falls, NY, on a completely different GE project and the "train project", as we called it, just faded away. It's very interesting to see your video describing today's reality of Distributed Power. It's been 50+ years for me wondering what ever happened to the "train" idea - now I know. Thanks for a great video! CRS

[@bc-guy852]

Very cool!

[@wb4514]

The project was "put on hold" so that the Corp could ship your dad out so that they could steel his idea and not pay him for it.

RC (radio control) cars,coupled to locomotives was how this was first done. It's something you can Google for more info. All the radio gear was in a box type car. Kinda neat evolution. Not a lot of meat here. Good editing😊

Years ago while in the military I had the honor of serving with two guys both Master sergeants that had worked on railroads before coming in service john worked for one up in Illinois where he was from and Dale had worked on the old MOPAC line in Oklahoma area. Dale told me, and I have found this to be true, that the railroad is still the best barometer on how the economy is. As long as the economy is strong and growing you will always find more trains rolling due to the amount of goods that need to get to market. When the economy is sluggish or just bad and not growing you will find fewer trains and they will be longer. In the last 2 years I have watched this play out with the inflation and a struggling economy. UP here in Arkansas are running fewer and longer trains than they were 3 or 4 years ago

[@pianoboylaker6560]

You Yanks are so, so lucky to have these magnificent beasts to enjoy. Our trains in the UK are really small in comparison. But...., and it's a big but..., I live where the very first train began. The "Rocket", George Stephenson's first trial locomotive ran right passed the house I now live in during the Rainhill Trials from 6 to 14 October 1829 in Liverpool. My house is much older than that and it is still in good condition considering its age, it is certainly in better health than I am. However, not as much rail traffic runs in Britain now and that's a damn shame. So, you are still lucky to have what you've got. Many thanks for the pleasure I get from videos like this but it also gives people like me, not in the US, a glimpse of what it's really like where you are that we wouldn't get to see without these videos and people like you who go out of your way to put them on YT for us to enjoy.

[@andrewstrait4379]

Danny, NS tries to build our trains by destination. For example, I'm working a 153 (daily Greensboro, NC to Birmingham, AL manifest) today. I predict leaving Linwood, NC I'll have 50-70 Charlotte cars on the head end, with 50-100 more behind that cut bound for points south of Greenville, SC (Toccoa, Doraville, Atlanta, and Birmingham). The Yardmaster in Charlotte will have cars bound for Spartanburg, SC on the head end of one of our pickup tracks in Charlotte, so that when we get to Spartanburg this evening, our set off will be on the head end. Building trains this way unfortunately distributes the tonnage poorly through the train, but DP does help with that. The 153 I'm working today has DP about half the time. The northbound sister train, 154, has DP almost every day.

DPU trains are especially common in winter time to improve braking ability and response time and ensure consistent air pressure throughout the entire train. DPU systems are Also used in hilly or mountainous tracks to reduce train slack and help prevent as well as the potential for a "stringline" derailments.

[@jamessimmons3968]

Dpu,s are only used to give extra power to the train and helps prevent stress in the couplers on long heavy trains. The braking is controlled from the lead locomotive. Modern locomotives have a built in Dpu function, not remotely controlled, it uses sensors in the couplers and the brake pipe air pressure to automatically activate the locomotive when the power is needed.

[@johnandrus3901]

@@jamessimmons3968 DP is integrated into the newer locomotives so you don't need to close a breaker for it to be active. The DP reacts to either the throttle input from the lead locomotive or from the commands of the engineer through the use of the fence to operate it independent of the lead locomotive. Auto control automatically puts up the fence when activated and controls the DP units. I've never had a DP unit that I couldn't control from the lead locomotive. DP units also help with braking and will pump up long trains quicker upon release.

[@em1osmurf]

it is noteworthy that the incidence of "busted knuckles" in the northeast and alleghany mts has decreased significantly since the proliferation of DPU arrangements. CP, CN, CSX, BNSF, and NS benefit from it. don't know about the rest of the continent.

[@general5104]

Danny, I don't know if you know this, or not. You stay up on things really well...Distributed Power, used to be called RADIO TRAINS. They started out using a short red boxcar with a white top and about 6" down from the top was white, so it wasn't so hot on the inside. They also had thermostat controlled exhaust fans. There was a door, like a cab door, on each end. It had round donut mushroom vents on top. It also had 5 top fed "CAN" antennas up there 2 on each end, separated as much as possible and one 1/3 back from the "A" end. It had metal islands built up inside, welded to the floor, All rebar welded to the floor and poured with concrete. This was so they were bottom heavy. There were walkways around the islands. Plenty of conduit and cableing and an ECR receptical, mounted on each end of the car, and to the right of where the end door was, (to plug an ECR cable from tge ECR receptical on the Locomotive to the ECR receptical on the Radio Car. and a jutt rack to suspend the ECR cable. ((ECR = Emergency Cranking Cable. Female two prong receptical.)) One "T-Rack" voice radio, mounted below the 1/3 back antenna, for voice communications for linking up with the Lead unit. Then you had several "Channel Boxes" mounted on each end, in big square tubing frames, welded to the walls & floor. They were hooked to a 27 pin TRAINLINE MU receptical, out on the end of the car above and on the right side, (facing the coupler) and an MU Cable connected to the Locomotive and to the Radio Car. Lots of quick disconnect cables covered the ends. (inside the car). They were set up so when the "Radio Car" wasn't being used, they could snatch the radio boxes off and hooked to test equipment and everything verified to be right, and they were kept in the Radio Tech Building under lock & key. The Radio Car, WAS the Lead unit, in relation to the Locomotive it was connected to. The locomotive's batteries were connected to the car via the ECR cable, so the car had plenty of power. Ok, those racks, like I mentioned earlier, that held the radio LETTER BOXES or Channel Boxes. (the names were the same, just dependant on who was talking) were also in the Short Hood Nose of the lead Locomotive. There were switches that had to be set on the panels JUST ALIKE for that consist. You couldn't have any other link set, with those same combinations.

[@MrHotrodf1]

Super cool info, thanks for sharing!

[@slamdvw]

I didn't film it, but I was working in a switch yard and the engineer was well versed in using his remotes to switch. Empty coal train came in, three on the head end - no DP. It was to be switched, then power modded to have a DP on it before heading to the mine. As luck would have it, the second unit was facing the correct way to be a lead. Engine one became the DP, engine 2 became the new leader, engine 3 was a trail to unit 2. Brakeman was operating the switches, conductor was on the ground giving hand signals to the engineer, who was sitting in unit 2. He ran his remote from the cab of unit 2, was kind of neat to see! I hear it's super illegal, but... what do you do. The stories those guys had were pretty entertaining.

[@tracylemme1375]

In the 1960s Southern Pacific ran a daily ore train from Eagle Mountain Mine to the Kaiser Steel plant in Fontana CA. It always had three units at the head and two units in the middle. It was reported that at the time it was the heaviest regularly scheduled train. It had one hundred ore cars an a caboose.

At the first glance, US railroads look much less sophisticated than our European mostly-electrified network and locos (...and traffic control!). But on the other hand it's insane - the power, tracktive force and length of trains, especially intermodal. WOW! Remote DP is a beautiful solution to problems unknown in Europe. We sometimes add a loco on the butt, but only for some mountain lines and problematic slopes.

For someone who knows almost nothing about trains, knowing about the different kinds of propulsion would help understand why observing the trains in operation is fun.

[@jessiebullock]

I’m loving the drone shots you get. Thank you for your work.

[@roycsinclair]

I see distributed power trains like this regularly, best one I've seen started with five engines, then 3 engines, then one engine and ended with another pair. And yes, we get very long trains. The track I cross regularly has the potential to have as many as 63 trains each day though it normally doesn't get that many.

[@jimmhenry657]

i have seen my share of interesting trains with consist of locomotives put in different places all throughout the entire train

[@donaldstanfield8862]

Wow, where is that?

I didn't even get to think the full question "why aren't those containers double stacked like I've seen elsewhere?" when you brought that up and answered it. A++

[@whatissixtynine]

the production quality of your videos is joyful

[@roxannemanzone9351]

Danny, I think this was one of your best videos! Great to see the NS action and the locations you filmed were awesome. I especially enjoyed the drone footage. The DPU info was really informative. Kinda felt like I was trackside through the whole video.

[@549BR]

It seems to me that "precision railroading" is a cover up term to hide the real reason for long trains; reducing personnel by one or two thirds. A fifteen thousand foot train is operated by two people whereas in the past it would have been three trains with six people.

[@bluegrassman3040]

It’s the railroads version of lean manufacturing.

[@rrai1999]

Look at all that unnecessary text! The whole thing can be summarized in two words: "Cutting corners."

[@alexander1485]

Our territory is eesigned for trains 7000-7500 feet. Anything over 8600 feet and it can only fit in 2 sidings between yards, not to mention longer it takes to walk back, check a problem or stop between sidings blocking more crossings

[@tedjackson5272]

@@bluegrassman3040 I feel your pain. Run these two machines , help this guy run his machine and set up a third machine.

1980's version of downsizing. As a brakeman for the former SP, we had a crew of four. I guess as technology advances, we may see unmanned trains operated like unmanned drones.

[@general5104]

I do LOVE the quality of the narration ! He knows his stuff. He leaves in all the train sounds, has his radio scanner picking up cross-talk and he explains everything ! Here's something you may not know, on engines that DON'T have the dropped-nose (they have a full windshield), the Crossing Bell will be mounted high up above the sand tank, just above the head lights. Imagine looking AT the back side if the bell. The control stand will be on the RIGHT SIDE of the engine, looking at the BACK of the bell. (that's your trivia for the day). Knowing that enables you to know which side the engineer will be on.

[@allenbrown6026]

This reminds me of the films I watched back in the 70 s in elementary school . The narration is spot on !!! Editing as well

[@distantsignal]

Wow! I'll take that as a compliment, I guess. Like the old Encyclopedia Britannica Films? I though I had a little more personality than that. I'll work on it. Ha!

[@chud327]

IKR, there was about a 4 hour break between trains in Folkston this year. However, the fans waited patiently for the trains... If I had been fishing and caught nothing in 4 hours, I would have put my rod and reel down by then.

[@everettrailfan]

Haha, we frequently have 6 hour breaks between trains here on the Scenic Subdivision, mainly due to maintenance because it crosses the Cascades. Still, it's kinda frustrating lol.

[@cup_and_cone]

Better than one train every 24 hours on the old CSX Panhandle line (especially when that one train is at night)...thanks to CSX selling it off a couple years ago to RailUSA/FG&AR. It pretty much killed rail fanning in the Western panhandle.

[@everettrailfan]

@@cup_and_cone Oof, so basically it's a shortline now?

[@cherylsims5636]

@@cup_and_cone theres always the But. They sold it to BNSF. So I'm sure they have plans for it. And of course we still make runs along it.Privately I think it's a maintenance deal.

[@cup_and_cone]

@@cherylsims5636 BNSF bought what? I haven't heard anything? RailUSA's website still shows them as owning it.

[@Jumpingoffthecliff]

Thanks for another informative and entertaining video. I recently rode in a DPU and was surprised to discover the engines completely shutdown during crew changes and other longer stops.

[@Diddley-js6lf]

I grew up most of my life along a CSX Rail Yard in Flint Michigan. I played on every kind of Railcar and Engine that passed through that line, that particular line runs south to Florida somewhere but north up the The Soo St.Mari At the Canadian Border. I moved away from my childhood home a few miles north but along the Same line I grew up on, so when I hear them Horns Blowing I get this Truly Loneliness feeling because all my family and friends are all just about gone now. I still find myself going down to the switch yard at the Carpenter Rd. Yard in Flint City.

[@robertlloyd7167]

Excellent videography, excellent commentary!

I love all of your videos and stories on KZbin on trains everyday they are good train videos

Thank you Danny for putting together this amazing video.. Your editing and color commentary is the best I’ve heard. Your knowledge is incredible.. along with passion for railroading. Really enjoy the drone footage.. game changer! Have a great Memorial Day Sir🙏🏽

This is soooo fascinating. When I was a kid, I lived in Jax. My dad worked for ACL, then SCL in the office. We rode the train often. I miss the Ubion Station

[@stephenhope7319]

Thanks for the time you took to film this. What we saw was American economics on the move. Priceless.

[@GeorgiaAstronomy]

Thank you for the descriptive DPU understanding. I never even considered drag coefficients as a potential asset for this. Love your content and demeanor. You do excellent voice over!

Another Wonder Video, KCS has been doing alot of Mid DPU's on their Grain trains to Mexico Lately. Keep up the Good work

[@royreynolds108]

The KCS has been using midtrain locos for years.

They've start mid-dpu's on the Speedway just a few months ago.

I remember times down here when they ran dpus woth only a single car behind it Years ago

Yeah we've seen a few with maybe 8 cars behind the dpu.

This is a gold mine of railroading, really great stuff. One thing to make it really better for who doesnt know much of the area mentioned: add some maps or visuals that help people know where your talking about. I think it would be great if it happens

[@firecaptain5405]

A fantastic production. Thank you Danny for all that you do. Well researched and accurate content.

[@wafflesnfalafel1]

nice vid - thanks. The shrimp looks mighty fine there too. We get DPU units on the unit oil and unit coal trains out here that go over one of the passes in the Cascade mountains in Washington state - frequently two units on the front and two more on the back.

[@brucescott240]

I KNEW I'd heard that buttery tone and cadence elsewhere! That voice is too pro to keep locked away on you tube. Heard your narration on All Girls Garage today and said AH HA! Gotta be Distant Signal. Love the informative videos.
