Abstract

A communications device is provided for routing a locomotive over a track layout in a train yard. The locomotive is operable over a plurality of alternative track routes to reach a respective destination from a plurality of possible destinations in said track layout. The track layout includes a plurality of switches configured to alter a route for a locomotive running along the track layout. The communications device may include a first user display for use in commanding a desired destination for the locomotive within the track layout by setting the state of the switches along the route to the destination.

Claims

1. A communications device positioned wayside in the yard for routing a locomotive to a desired destination in a rail yard through a track layout comprising a plurality of rail tracks connectable to one another in response to a respective switching combination applied to a plurality of remotely controlled switches for interconnecting one track to another track, said communications device comprising:

a memory configured to store information indicative of the tracks in the yard and the switches interconnecting said tracks;

a user interface for displaying information indicative of the tracks in the yard and receiving a user input regarding a set of desired tracks to be interconnected to set a route for enabling the locomotive to reach the desired destination in the rail yard;

a processor responsive to the user input to identify the switches to be actuated to interconnect the set of desired tracks and the positions for the switches to make the interconnection of said tracks;

a transmitter configured to wirelessly transmit a switching combination to be applied to respective ones of the plurality of remotely controlled switches to implement said at least one route; and

a receiver responsive to information received from said respective ones of the plurality of remotely controlled switches regarding a status of the switches for interconnecting the tracks to set the route for reaching the desired destination.

2. The communications device of claim 1 wherein said user interface comprises at least one stationary user interface panel disposed at said rail yard.

3. The communications device of claim 1 wherein said user interface comprises a hand-held user interface.

4. A communications device for routing a locomotive over a track layout in a train yard, said locomotive operable over a plurality of alternative track routes to reach a respective destination from a plurality of possible destinations in said track layout, said track layout including a plurality of switches configured to alter a route for a locomotive running along said track layout, said communications device comprising:

a graphical user interface for commanding a desired destination for said locomotive within said track layout, said graphical user interface configured to display a representation of said track layout, and wherein said representation allows an operator with remote control means for controlling movement of said locomotive to monitor operational conditions of the switches that may develop along the route of the locomotive.

5. A communications device for routing a locomotive over a track layout in a train yard, said locomotive operable over a plurality of alternative track routes to reach a respective destination from a plurality of possible destinations in said track layout, said track layout including a plurality of switches configured to alter a route for a locomotive running along said track layout, said communications device comprising:

a user display positioned wayside in the train yard to enable an operator at the train yard with remote control means for controlling movement of said locomotive to command a desired destination for the locomotive within said track layout by setting the state of the switches along the route to the destination through a wireless communications link, wherein the user display is accessible by the operator at the train yard, thereby enabling said operator to individually (1) control movement of said locomotive, and (2) directly set the state of the switches along the route to the destination through the wireless communications link independent from a train yard control system.

6. The communications device of claim 5 wherein said communications link comprises a direct communications link between said user display and the plurality of switches.

7. The communications device of claim 5 wherein said communications link comprises a communications link through intermediate communications equipment disposed between said user display and the plurality of switches.
