scope:

This standard specifies the interface functionality among propulsion, friction brake, and train-borne master control. The standard encompasses performance parameters, communication methods and the means for measurement and verification of performance. Third party systems performing functions traditionally carried out in one of the above systems are also covered.

Purpose

IEEE Std 1475 contains specifications leading to standardization, compatibility and interchangeability of functional protocols for interfaces among train-borne master control, propulsion, friction brake, spin-slide control, etc., reducing first cost and recurrent integration problems. This standard, in use by car-builders and system suppliers, has lowered costs, reduced vehicle introduction problems, improved reliability, and facilitated upgrades. It further helps prioritize safety functionality.
