Summary

This Standard was formerly titled “Passenger Electronic 26C Emulation Braking System—Performance Requirements for Passenger Applications” in the previous publication of this document. This standard identifies the minimum performance requirements for the operation of passenger electronic 26C emulation brake systems in service on passenger train equipment. Emulation operation allows ECP-equipped cars to be interoperable with cars outfitted with conventional pneumatic brake valves, such as a car equipped with a conventional 26C valve. This document addresses the performance requirements for entering/exiting Emulation, operating in Emulation, fault detection in Emulation, and the key features and functions of Emulation.
