Abstract
A head of train device is configured to examine messages received from end of train units other than the end of train unit attached to the same train and to alert an operator to the presence of an end of train unit from another train that indicates that the end of train unit from the other train has stopped. The indication can take the form of a zero brake pipe pressure.
Claims21
A method for enhancing the safety of a train, the method comprising the steps of:
- storing on a device mounted onboard the train a first identifier of an end of train (EOT) unit, the first identifier corresponding to a first EOT unit attached at an end of the train;
- receiving on a device mounted on the train a message from a second end of train unit, the message having a second identifier of the second EOT unit, the second identifier being different from the first identifier, the second end of train unit being located off the train;
- and
- alerting an operator of the train as to the presence of the second EOT unit if the message indicates that the second EOT unit has sensed a zero brake pipe pressure or indicates an emergency condition.

A device for enhancing the safety of a train, the device comprising:
- a processor located on the train;
- a memory connected to the processor;
- and
- a transceiver connected to the processor, the transceiver being configured for wireless communication with an end of train unit;
- wherein the processor is configured to perform the steps of:
- storing in the memory a first identifier of an EOT unit, the first identifier corresponding to a first EOT unit attached at an end of the train;
- receiving via the transceiver a message from a second end of train unit, the message having a second identifier of the second EOT unit, the second identifier being different from the first identifier, the second end of train unit being located off the train;
- and
- alerting an operator of the train as to the presence of the second EOT unit if the message indicates that the second EOT unit has sensed a zero brake pipe pressure or indicates an emergency condition.
