Abstract
An EOT emergency arming apparatus and method in which an engineer at the HOT operates a standard air brake control and responds to a resulting report of change in air pressure from the EOT within a prescribed short interval. The response is a signal which includes the EOT unique identification code, and if received within the short interval is interpreted by the EOT as if the EOT ARM switch had been activated.
