Most railway trains use an End of Train (EOT) device to communicate from the front of the train to the end of the train. The wireless protocol for these communications is not secure. This would allow a hostile person to initiate at will an emergency braking event with most freight and passenger trains. This paper examines the vulnerability and recommends a new protocol to reduce the threat. The protocol is backwards-compatible with the current protocol.
