Rail Industry Component:
New York Air Brake Corp., a Knorr Brake Company: CCB II - Advanced Locomotive Air-Brake System

In 1998, New York Air Brake introduced its second-generation locomotive electronic air-brake system, CCB II (computer controlled brake). CCB II is a microcomputer-based system designed to provide full automatic and independent brake control for mainline locomotives. The company says its network-based design permits faster response and its self-diagnostic routines and LRU (line-replaceable unit) approach reduce maintenance costs. New York Air Brake's EPCU manages the pneumatic interfaces between the locomotive brake system and the consist. It controls the locomotive's brake cylinders, brake pipe, independent application and release pipe and the actuating pipe. A redundant pneumatic backup system is integrated into the EPCU, and provides backup for partial loss of computer control in the lead locomotive or functions in the trail mode when the system is unpowered.
