Really? What about when freight trains brake? You realize that freight cars don't have DYNAMO brakes? Also, some current IRT cars have straight air brakes on trailer trucks.And i know that regenerative braking is dynamic braking...but a more complex circuit is needed to detect a load at the third rail. There is nothing bad about dissipating heat through wheels, for many years, that is the only way it was done. And if anything, you can have discs mounted on the axle too, so you an dissipate heat through them as well. The good thing about eddy brakes is that there are no brake pads to wear out, just make sure you se a heavy enough wire with a good enough insulation. |
