TRAIN END AND TRAIN INTEGRITY CIRCUIT FOR TRAIN CONTROL SYSTEM
First Claim
1. A train system comprising:
- a plurality of train units including a first train unit and a second train unit coupled to the first train unit, each of the plurality of train units comprising;
a controller configured to detect a change in train configuration of the plurality of train units;
train integrity signal lines spanning each train unit of the plurality of train units and coupled with the controller , the train integrity signal lines are configured to transmit signals between a front end and a rear end of the train system, the signals indicating a status of train integrity of the train system; and
a plurality of relays in communication with the controller, and configured to indicate a coupling or non-coupling status of each train unit.

Abstract
A train system that includes a plurality of train units including a first train unit and second train unit coupled together. Each first and second train unit includes a controller configured to detect a change in train configuration of the train units, and comprising a plurality of inputs; train integrity signal lines spanning each train unit and coupled with the controller at the plurality of inputs and configured to transmit signals between a front end and a rear end of the train system, the signals indicating a status of train integrity of the train system; and a plurality of relays in communication with the controller, and configured to indicate a coupling or non-coupling status of each train unit.
