Abstract: A locomotive comprises a DC power bus, traction motors, batteries, and a charging source, but has no prime mover engine. Each traction motor includes armature and field windings connected in parallel across the DC power bus. The batteries provide power to the DC power bus when in a motoring mode, and receive power from the DC power bus when in a charging mode and a dynamic braking mode. The charging source is connected across the DC power bus to provide charging power to the batteries when in the charging mode. The traction motors also provide charging power to the batteries when in the dynamic braking mode. The power from the charging source is less than the power that would be provided by a prime mover engine. The charging source provides no power to the traction motors when in the charging mode.

Abstract: An arrangement for driving a locomotive has various energy-provision systems. The locomotive contains a main energy-provision system as the main system and a drive system. Energy provided by the main system is supplied to the drive system as drive power and is used by the drive system for moving the locomotive. A railroad car carries at least one additional energy-provision system as an auxiliary system. The auxiliary system is used in a manner which is temporally offset from the main system in order to supply drive power to the drive system. Components which can be used by both the main system and the at least one auxiliary system are implemented only once and are used jointly by both the main system and the auxiliary system. Components which are used exclusively by the auxiliary system are arranged on the railroad car.

Abstract: In an embodiment, a system for detection of trains at railroad crossings is provided. The system comprises a field-deployed detection and reporting device comprising a microphone, a communication module, a microprocessor, and an application. When executed on the microprocessor, the application receives data describing sounds captured by the microphone and identifies frequencies of a first received sound. The application also transmits, based on the identified frequencies and a formula, a first message via the communication module. The first received sound is generated by a warning bell sounded at the railroad crossing. The first message is received by a backend server that issues a first broadcast based on receipt of the first message. The application further determines that the first received sound discontinues. Based on the determination, the application sends a second message via the module to the backend server which issues a second broadcast that the crossing is reopened.
