Regenerative Braking Boosts Green Credentials

This article presents a few of the advantages of regenerative braking that are leading it to take over rheostatic braking as a means of energy conservation. Rheostatic braking uses a direct current traction motor and then dissipates the received current into banks of resistors, which is useful as it substantially diminishes the need for friction brakes. Regenerative braking relies on the same principle, although it transfers received current to an overhead line or a third rail. The authors emphasize that, while cost savings from the energy savings achieved from such systems are appealing, there are also substantial peripheral benefits as well, such as diminishing parts and maintenance for friction brakes. Smart braking systems help to monitor the relationship between friction brakes and regenerative brakes on these trains.
