20120095627METHOD OF ALERTING HORN RULE TIMING - The present method includes determining the locomotive's present location on the track; and determining the present speed of the locomotive. From the present location of the locomotive and the present speed of the locomotive, a horn rule locations on the track for a point of interest is determined; and the operator is alerted to the horn rule location on the track. The horn rule location may include horn start and stop locations and horn free zones.04-19-2012
20120095626COMMUNICATION SYSTEM FOR A RAIL VEHICLE AND METHOD FOR COMMUNICATING WITH A RAIL VEHICLE - A communication system for a rail vehicle includes a transceiver assembly, a selection module, and a monitoring module. The transceiver assembly selectively communicates a data signal over a plurality of communication channels. The data signal is related to distributed power operations of the rail vehicle. The selection module is communicatively coupled with the transceiver assembly and switches the transceiver assembly to any of the communication channels. The monitoring module is communicatively coupled with the selection module and determines a load parameter of one or more of the communication channels. The load parameter is based on a population value of the one or more communication channels. The selection module switches the transceiver assembly to a selected channel of the communication channels based on the load parameter for communicating the data signal over the selected channel.04-19-2012
