CCB-26

Overview   |   Features & Benefits

The CCB-26 electro-pneumatic control unit (EPCU) is mounted in the locomotive brake bay. Its modularized line replaceable units (LRUs) control the development of all pneumatic control pressures. Features and benefits include:

Reduced repairs, road failures and life-cycle costs
26L equipment typically requires eight overhauls in its service life whereas CCB-26’s minimum five-year COT&S cycle significantly reduces locomotive downtime and maintenance costs. Its higher reliability reduces repair costs by 75 percent, road failures by 75 percent and cuts life-cycle costs overall by at least 38 percent.

Simple installation
The driver’s electronic brake valve (EBV) interfaces with the CCB-26 brake system. The EBV installs in the same mounting envelope as the 26C brake valve located in the engineer’s stand, and is used by the engineer to control the independent brake, automatic brake and bail-off.

The EBV includes the lead/trail switch and the ER setpoint (feed valve) switches required for setting the brake system operating mode and equalizing reservoir setpoint.

Operators see faults on an LCD screen mounted on the driver’s brake valve, EBV. This screen also shows routine advisory instructions such as penalty and emergency reset.
