The video of the MRL train west of Mullan Pass is 2.2 percent going west.... The manned helpers control the throttle... brakes are controlled by the head end. There is another section of manned helpers is used from Livingston to Bozeman ... same type of operation.

2007 i was working with UP in FT worth TX and i asked them why every train has a dpu, he said it gives them 8% better fuel economy, control from both ends of the train and less train separations due to draw bar forces on a grades. think of it as a big radio controlled car. down side is in hills with lots of curves you can lose radio signal

Subscribed! You did a great job on describing DPU's! Learned a lot.

Hey man... Cp rail is the pioneer of DPU opps. And started it and ran continously on coal trains in the 70s. They started this with rebuilt B units to house the radio equipment. The CP roster of sd40-2s was #ed for slave and masters in the 58xx and up .. there is a lot more info on this. Plz update the video.

If I remember correct, SOUTHERN was also very early to do/,try stuff like this in the late 60's/ early 70's, especially on the line over Saluda Mtn.

@@martindoyle831 no… Southern Railroad did it from the 60’s . They had radio controlled equipment in converted boxcars

DPUs reduce couple and draw bar stress. DPUs are in wide use so the hookup and test costs are minimal compared to the benefits. As technology increases so will the the use by RRs increase.

Back in the day, no railroads used reflective vest

out west those are probably the wire connected DPU's instead of the wireless jobs AC!! if you want some info on CSX you might want to get a hold of DJ over on DJ's trains channels he's an engineer for the cheapskate express as the track gang around here refers to CSX!!

Giving out how to instructions for DPU setup is sensitive need to know information. It should be for Railroad Employee consumption only, not for the public at large.. please edit this out

Come on now, the main advantage of DPUs is that they allow more efficient performance while getting rid of a train crew to man them. Helper sets do everything DPUs can do, but of course they require a crew to man them

Way to call it how it is automation to put a guy out of a job

@massmike11 5 ай бұрын

MU’s however only require one crew for multiple units also. Helper units require a crew because they do not stay with train, they are temporary and let off a after a short push to get the train over the section where more power is temporarily needed. Then they move on to the next train that needs help on that section. Witch means that they are capable of independent operation.

I am pretty sure that there has to be a human in the main locomotive and a human in the DPU to coordinate and press buttons on the DPU system and the lead locomotive

Nope

@ocsrc 5 ай бұрын

@@7171-Ws6 someone has to be in each locomotive and set the levers for the manual brakes and the throttle and turn on the breakers and switches. Once it is in DPU mode they can disconnect from the main locomotive or add the DPUs to the Main locomotive, but someone has to go in and turn each locomotive on and flip the breakers and insert the throttle and move the levers. As long as it is left running then it can be remotely controlled but once you turn it off or one of those levers is manually moved , it has to be manually moved again to the DPU state It would be great if you could remotely turn on the breakers and start it up and move a locomotive without anyone being in it. You wouldn't need yard crews to put trains together. Just someone remotely watching a video feed.

@mrmax128 4 ай бұрын

yes; someone has to go to the DPU engine and set it up for DPU mode, and then they go to the lead and set it up for lead. Typically yard hostlers (who move engines around in the yard) set this up
