How Do Train Brakes Work?

[@WTC2014]

Freight locomotives have something called the dynamic brake. It works by turning the traction motors of the wheels into generators, and taking the generated current through resistor banks and expelling the energy as heat.

Thanks for the info!

Air brakes usually open the shoes from their default closed state held by springs

I wish for a video on How the wheels of diesel hydraulic locomotive works . How the wheels are turned . Are yhe wheels turn by hydraulic fluid motors

All our trams in my city (Bielefeld Germany) have regenerative braking so it is more common than you suggest - I think most German trains also do it but I am not sure.

@0:58 "Even with its breaks"??? So trains take longer to stop because they take breaks while they're coming to a stop?

1:03 that's the accelerator pedal; there's your problem 😂 Interesting video though.

[@grow723]

I never noticed, thank you.

Awesome job!

Thank you

How is it that the video says we now know the secret of braking? We don't! Had it described, say, the triple valve function and the pressure reservoir, it would have gone most of the way to telling us the "secret" of train braking.

Trying to make the video as simple as possible so everyone can understand. The full details on how a train brakes could take an hour to 30min video, which makes everything seem boring Triple tank function allows air inside, it was mentioned that air is actually used.

@@grow723 brakes, not breaks. And no, the fact that high pressure fills the tank and low pressure lets the tank apply the brakes can be explained easily in very few sentences.
