Abstract: A system for adjusting wheel adhesion levels on multiple locomotive axles in a rail vehicle consist is provided. The system includes a first controller associated with a lead locomotive and a second controller associated with at least one trailing locomotive. A wheel adhesion level sensor is configured to detect a low wheel adhesion level at an axle and transmit that information to the first or second controller. The first controller adjusts the load being delivered to the axles by the motor in response to the low wheel adhesion level.

Abstract: A method for controlling communication between an off-board system and a railway wagon is provided. The method includes detecting a failure in communication between a first modem and the off-board system by, a first control unit. The method also includes determining a working mode of a second modem via a second control unit, by the first control unit. The working mode includes at least one of operational and non-operational. The method further includes receiving an identification number of the second modem from the second control unit when the working mode of the second modem is operational. The method includes establishing a communication between the first control unit and the second modem for transmitting the data associated with the first control unit to the off-board system based on the identification number of the second modem.

Abstract: A data communication system for a locomotive consist is provided. The locomotive consist includes a primary unit and one or more secondary units. The data communication system includes a fuel level sensor associated with the secondary units. The fuel level sensor is configured to generate a signal indicative of a fuel level in a fuel reservoir of the respective secondary unit. The data communication system also includes a data controller communicably coupled to the fuel level sensor. The data controller is configured to receive the signal indicative of the fuel level in the fuel reservoir of the one or more secondary units. The data controller is also configured to compare the fuel level with a predetermined threshold. The data controller is further configured to determine if the fuel level of any of the one or more secondary units is lesser than the predetermined threshold.
