System for controlling movement of passenger train

Abstract

A system for controlling movement of a passenger train having a locomotive and a plurality of doors is provided. The system includes a door status sensor to determine open and closed status of each door of the locomotive. The system further includes a first control module coupled to the door status sensor and a relay coil through a first diode. The relay coil is energized on receipt of input from the door status sensor, when all doors of the locomotive are closed, and the energized relay coil allows controlling movement of the locomotive. The system further includes a door override switch. In an actuated condition, the door override switch allows power to flow from a power source to the relay coil, thereby energizing the relay coil. The energized relay coil allows controlling movement of the locomotive.

What is claimed is: 
     
         1 . A system for controlling movement of a passenger train, the passenger train comprising at least one locomotive and a plurality of doors, the system comprising:
 at least one door status sensor coupled to each of the plurality of doors of the passenger train;   a first control module operably coupled to the at least one door status sensor, the first control module is configured to:
 receive a first input from the at least one door status sensor, the first input being indicative of status of each door, the status being one of open and closed; and 
 indicate to an operator of the at least one locomotive to control the movement of the at least one locomotive when the status of each door is closed; 
   a relay coil operably coupled to at least one door status sensor, via a first diode, to receive the first input from at least one door status sensor, wherein the relay coil is energized when the status of each door of the passenger train is closed, and wherein the energized relay coil allows controlling movement of the at least one locomotive;   a door override switch adapted to selectively establish a connection with a power source when status of at least one door is open, to draw power from the power source; and   a second control module coupled to the door status override sensor and the door override switch, the second control module configured to:
 receive, through the door override switch, power from the power source; and 
 indicate to the operator of the at least one locomotive regarding the overriding of the open status of the door of the passenger train, 
   wherein the actuation of the door override switch allows flow of the power to the relay coil via a second diode, wherein the relay coil is energized on receipt of the power from the power source for controlling the movement of the at least one locomotive.
