I always thought diesel hydraulic was like diesel electric, but instead of electric lines, it used hydraulic oil lines, and would spin hydraulic motors on the axles. These are what i thought diesel mechanical locomotives were, since in all effect, there is a mechanical linkage between the flywheel and the axle.
Very interesting. I find it interesting how electrics and hydraulics can often be interchanged. In aircraft, things like flaps and landing gear are usually powered hydraulically. But some planes use electric actuators instead because an electric system is going to be much lighter than a hydraulic system with its lines and pumps.
Nearly all German Diesel-Locomotives have hydraulic transmission. This was the most-know workhorse of "Deutsche Bahn": en.wikipedia.org/wiki/DB_Class_218 The gearbox uses often fixed helical gears, but sometimes shifted gearboxes are used.
Thank you very much my man, I'd always wondered how diesel-hydraulics worked and this is a great stepping point for an idiot like me whos used to the usual Diesel-Electric operations in Canada.
Very nice explanation of the theory of diesel hydraulic loco. Only wished you should have elaborated on the stator functioning. i understand it is like a pump impeeler that pushes the hydraulic oil back on the the main diesel engine impeller and rotates only clockwise. The 90 degrees part was not clear. Is it axial flow that you are talking about?
Great job! I have one ambiguity. 1:26 - How is the second fan forced to stop working if the first one is still running? I mean, there's still transmission among them, flow is still active, am I right?
Yes, the flow is still active, but not enough to rotate turbine because the train is very heavy. On cars with automatic transmission with torque converter they are light so you have to hold the brake pedal, otherwise the car starts to creep because the flow is also still active.
Well done, a very good explanation. In terms of converting a given output from the diesel engine, which has the greater efficiency at the final drive of the locomotive wheels: diesel-electric or diesel-hydraulic?
Very nice explanation! But, what is the difference between a Diesel Hydraulic locomotive and a Diesel-Mechanical locomotive? Both of them use a Par Converter, don't they?
The main myth about trains is they take a long distance to stop. Really the true braking distance is not any longer than the braking distance of a car. So the next time you are walking along the tracks or need to drive across the tracks, go for it. Nothing to worry about! If the train is in any danger of hitting you, the engineer will be courteous and stop in a timely manner.

The only place i found a light but satisfying information about train in the whole web, great job!
Thank you :)

Danke Stefan for this information ...
The Hymek was slightly different, as it had an automatic gearbox connected via a fluid coupling (the Mekydro bit), like an automatic car.
Thanks for the update
Thank you, always wondered how these worked, straightforward and clear, well done 👍

Matt Brine Thanks man :)
Thanks for the quick and simple explanation!
The ML4000 C'C' was a nice Diesel Hydraulic Locomotive
Great job disall hidrolik trin enjn 💙💎 👍❤️🔥👑
Talgo xx1- 256 kmph
Uac turbo train- 275 kmph
Please check 🙏🙏
Good video thanks for sharing
Thank you

You didn't explain how the wheels are turned.i wish I could see this
Thanks for the explenation
Hope it was of use…
Great job man!
Thanks 😊
One question. Does the transmission after torque converter require gear mechanim or it works without gears in a locomotive?
Great job!

Mechanical uses a gearbox instead of a torque converter.
Great Video
Wow great
AVINASH PANDEY Thank you bro...
Bro do a video about myth abouts train .. i have heard lots of myths about train since my childhood
The Third Eye 👍

To the veels?
Yep
This is pappu locomotive
Just like the memes, an Indian man is teaching me how a diesel hydraulic works.
You sound racist man…

@@stevenbanaan Thanks for the clarification. Please accept my apology for reading it wrong…
@@TheTrainStory no worries mate :)
