Selective Operational Modes of End-of-Train Unit Based on GPS Information

Abstract:

In a method of controlling operation of an end-of-train unit (EOTU) of a train during travel of the train on a path, a GPS receiver of the EOTU receives first GPS data and a controller, based on the received first GPS data, sets an electrical/electronic device or system of the EOTU to a first mode of operation. After travel of the train on the path following setting the electrical/electronic device or system to the first mode of operation, the GPS receiver receives second GPS data. The controller, based on the received second GPS data, sets the electrical/electronic device or system of the EOTU to a second, different mode of operation.
