Wabtec? EPIC?II (Electro-Pneumatic Integrated Control) is a braking package based on the use of state-of-the-art microcomputer technology. It provides the logic for electro-pneumatic operators to
control the compressed air generated from the locomotive main reservoirs. The equipment includes an electronic cab control unit, available in the desk-style consol shown here. A micro-computer is
programmed to issue and interpret commands from both the cab controller and pneumatic control units. The pneumatic interface unit and optional cab display unit are designed to provide feedback
information to the engineer during equipment operation. The enhanced diagnostics built into the unit greatly reduce locomotive downtime during testing and troubleshooting.
