Hear in the uk we use locomotives assisting on the back of heavy trains sometimes . But we don’t call them helpers we call them bankers. Also we don’t use d.p.u in our trains as the freight wagons we operate are not fitted with the through wires that are needed for that kind of operation.
Great Topic and an Even Better job describing the DPU concept. Thanks for also describing the Difference between the DPU and the Helpers. Thanks AC. 👍
Thanks for watching Ken.
I think it's funny that DPUs are all the rage and Southern Railway was pioneering this years ago the radio control gear was in a boxcar or the first was B units from F sets.
Would be amazing to see dpus chugging up the pocono plateau
Love all the commentary. I don’t feel like a DA when watching these videos. Thanks for sharing and great video as always. 👍🏻🎥💯🚂
Thanks for watching Brandon.
@@Trains21 you’re welcome!
this is what i call a very usefull lay-out with commend about the concept of DPU and very cleared what's the big different between dpu and helper loco's. here in my country this kind of railroading doesn't excists.
thanks for the learning about this item
Just got to your video another enjoyable and informative 👍 one. AC have a safe and healthy holliday and can't wait to see what's in the future of 2023.
EXCELLENT VIDEO I LOVE THESE TRAINS..👍🎥🌟🌟🌟🌟🌟
I love engines on rear bnsf and union pacifc cp do it a lot mid train is cause make over the road quick then block traffic psr started it on union pacific so far growing used to it but its difficult when hired I will get more information
On CN, we ran middle and rear DPU. Usually depends on the length and weight..
@made-in-the80s thanks for helping me out
@made-in-the80s no I heard about that wow crazy
Fantastic video my friend like 9
Great coverage 😍👌
Like the Helpers along rear at Aloona and Johnstown
Excellent video AC.
Thanks Hans.
Ooh those ALCO’s ❤️❤️
Yep love the look and sound they make.
Excellent!!
Thanks Tony!
I'm liking the new corner logo AC! I've always wondered if when a dpu is commanded to throttle up by the head end unit, if it was immediately or what?
Thanks Rob, yeah it's pretty instantaneous unless something interferes with the telemetry.
you should have pointed out that DPUs are remotes and helpers are manned engines some get confused there from what i've seen on other channels!
Thanks AC. I am about two miles from the Lehigh line see CSX with DPU'S very often. NS I only see head end power
Thats strange in the Reading to Harrisburg N/S corridor i see DPUs quite often. Just filmed one around 4 this afternoon
@@BeeLineEast in New Jersey
@@DJinNJ08830 Ok there are some gradual grades on this line maybe that why i see them here ?
I thought helper units had a 2 man crew on them pushing
They do
Sometimes helper units are manned, but there's also distributed power units on the rear and middle of the train consist. The dpu,s units are automatic and don't need a operator on-board because everything is controlled from the head of train, thus using less operators to do the work.
How are the DPU's controlled from the lead locomotive? Air brakes use air hoses chained from one car to the next, but I don't believe there are cables on all rolling stock to connect the lead locomotive to the DPU. So how do they do it?
Computers, Remote Control from the leader.
Other than on video, the last time I actually saw a distributive set-up was on a very long UP dual stack container high-tailing it eastward in far northern Minnesota a few years ago... Six units on this one - One solitary leader (that's how I knew it was a distributive), three spread out in different sections of in-between, and two in the back... Must've been fully loaded because every car was double stacked!
@made-in-the80s - Whatever it was, it looked like something put together for a big-assed load! Since it was more or less headed in an eastern/southeastern direction, I figured it was bound for the Twin Cities or maybe even Chicago... I'd say especially to the Windy City because many of the logistics companies that transport goods to retailer warehouses, Amazon distribution centers, and such throughout that portion of the country are based in Chicago...
@made-in-the80s - Probably was... I didn't work in logistics itself, but years ago during a temporary stint within the distribution department of a local medium-sized high-end stereo/TV/entertainment equipment retailer, I did manage to visit an intermodal yard where almost like a ship, the containers are lifted off the double stacking train cars, right on to waiting trailer carriages, and then it's off to a specific wholesaler's or retailer's warehouse, container and all, as soon as the initial routing arrangements are made!
Hey AC, I was wondering if we could possibly get a video of the history of the Dupont connector
Don't know what that is.
what are “swing helpers”?
Are DPU's just newer technology of the older slave/radio cars that the Southern and later NS used?
I believe so, but I don't know for certain.
@@Trains21 Thanks
Thanks@made-in-the80s
👍@made-in-the80s
Alright
Are DPU’s usually unmanned (unstaffed)?
normally Yes.
I have found guys riding in them. It should be locked, but not always..
In my POV...
DPUs are remote-controlled whereas Helpers are human-controlled
*CMIIW
get to the fking point
Isnt it Distributed power not distributive? Never heard it called Distributive before
You're probably right! My mix-up!
