Regenerative Air Brake - how does it work?

[mikeg]

I notice that the brake type for a class 323 is listed on Wikipedia as a 'regenerative air brake'.

I'm familiar with air brakes, and regenerative braking whereby the power is fed back into the OHLE as in a Pendolino, or the kinetic energy into a flywheel as in a Parry People Mover, but what is a regenerative air brake and how does it work?

In layman's terms it's regenerative and air driven.

Hope that clears it up for you



Seriously tho' I believe as the train brakes compressed air is produced which in turn is used to propel the unit when it accelerates again.

How, I have no idea.

Sounds like it needs a slash or comma. Anyone with a Wiki Account want to do the honours (I'm not at home so no Lastpass to log in with!)

No, it is two separate brakes as starrymarkb suggests.

The Wikipedia entry has now been amended as per above suggestion.

Indeed,

An actual air driven regenerative brake would not work on a unit of this size...

Thanks for the information. I'd been wondering for some time actually but was too afraid to ask. Just shows that 'Wikipedia says it so it must be true' isn't true at all!

I think that this attachment might clarify the thinking here and explain much.

I'd say what it shows is that punctuation is important.
