Are there any energy-recuperation systems for subways/metro/underground using the brakes?
I heared such a system was still in the development fase in Japan (for above-ground trains). Recently I read that there already is such a system for years in the metro of Brussels. Could this be true?
----------
using the friction energy of the brakes to generate power for the train
Well, the simple answer is yes and no.
nothing that uses the friction or axle brakes that I know of but the most efficient way to brake a train is using "dynamic or regenerative" braking where the axle mounted electric motors are reconfigured to become generators causing a very effective retarding force.
I worked on a railroad years and years ago that did in fact have that very same system, it was all electric, as trains went into braking mode the traction motors became generators, electricity generated was put back into the lines and made available for other trains. There were substations every 30 miles or so to regulate the amount of power available for trains, adding to or subtracting from as needed to keep the line voltage stable.
In effect, one train going downhill was actually "pulling" another train coming up that same hill.
System was installed in the early 1900's and worked so well that they took it out so the oil companies could sell millions and millions more gallons of fuel.
