Project: EMU – Brake Control Unit

Innovation in Braking Systems. Contract Manufacture.

The Brake Control Unit is a system used on modern, dynamically braked EMU vehicles, to ensure that air and dynamic braking acts in co-ordination. It interfaces with the train master controller.

An electronic signal from the electric (dynamic) brake, indicating the brake effort achieved, is compared with the brake effort demanded by the driver or an automatic control system. It will then call up additional braking from the air brake system if required.

A$1.5 million contract

Australian Rail Technology was contracted by Knorr Bremse Australia P/L to supply pre-assembled Brake Control Units (BCU) for:

  • 40 Perth Urban Rail Development (PURD) EMU train sets for WA Goverment Railway in 2004-2005 and 2008-2009
  • 65 Interurban Multiple Unit (IMU) for Queensland Rail trains in 2006-07, 2008-09 and 2009-11

ART supplied locally sourced enclosures, sub-frames, internal wiring, and testing. The underfloor mounted electronics enclosures were supplied at an IP65 rating. Custom in-house test equipment was developed for both projects.
