ABSTRACT:
A communication system for a distributed locomotive power/brake control system for a railroad train having a lead locomotive and one or more remote locomotives. Command and status signals are communicated over the system between the lead and remote locomotives. Each communicated message includes an information segment comprising the command or status information, and an error control segment for detecting errors in the information segment. The error control segment further comprises cyclic redundancy code words and parity bits formed according to the horizontal or vertical parity of the information segment and the cyclic redundancy code words.
