An energy recovery system for a power system is disclosed. The power system includes an engine, a generator driven by the engine, an electrical bus configured to receive electrical power from the generator, an exhaust conduit configured to receive exhaust gases from the engine, and a turbocharger coupled to the exhaust conduit. The energy recovery system includes a bypass conduit, a turbo-generator, and a synchronizer. The bypass conduit is coupled to the exhaust conduit, and facilitates a portion of exhaust gases from the exhaust conduit to bypass the turbocharger. The turbo-generator is coupled to the bypass conduit, and is driven by the portion of exhaust gases bypassing the turbocharger. Further, the synchronizer modulates one or more parameters of electrical power received from the turbo-generator based on one or more parameters of electrical power present on the electrical bus. The synchronizer transmits modulated electrical power to the electrical bus.

A device for communicating and monitoring railway tracks includes a plurality of communicating and monitoring terminals arranged along the tracks. Each of the terminals includes an image-capturing module, a wireless communicating module that allows for communication between the terminals and with a train, and a module for storing electrical power continuously supplying the image-capturing module and the communicating module. Each terminal also includes a power-generating module for supplying the module for storing electrical power. The power generating module recovers energy from the air displaced by the train running over the railway track. The device permits permanent monitoring by capturing images and makes permanent wireless connections available to the trains.

A rail vehicle compressor system comprises a compressor, driven by an electrical machine via a drive shaft, for producing compressed air for at least one compressed air tank. The electrical machine is activated at least indirectly via a control device for operating the electrical machine at least one nominal speed between a maximum speed and a minimum speed. At least one pressure sensor determines the pressure for the control device and is disposed in a compressed-air-carrying line downstream of the compressor. A final control element for continuously influencing the speed of the electrical machine is disposed between an electrical supply and the electrical machine, wherein the control device controls activation of the final control element. A method for controlling the compressor system is also provided, wherein, the compressor is operated at a variable speed in between the maximum speed and the minimum speed based on rail vehicle operating state.
