The invention relates to the supplemental generation of energy from a vehicle operation, and specifically to the generation of energy in connection to a vehicle's disc brakes in combination with brushless electric motor-generators. The aim of the invention is to provide a solution making it possible to provide a generator and a disc brake having a compact structure.

Example embodiments relate to implementing self-contained power sources for railcars. A railcar may include an air turbine that comprises a generator. The air turbine converts mechanical energy received from air to electrical energy by way of the generator. In some implementations, the air turbine is selectably coupled to the air brake system of the railcar and can convert mechanical energy received from pressurized air of the air brake system. The railcar can further include a pneumatic valve and a controller that can cause the pneumatic valve to open when the air pressure of the air brake system is at or above a predetermined level. Opening the pneumatic valve provides pressurized air to the air turbine from the air brake system and/or an exhaust pipe. The air turbine is a Wells turbine or a ram air turbine in some examples.
