IMTRAM

Metro Trains Melbourne (MTM) operates the EV-120, a non-self-powered track and overhead inspection vehicle, nicknamed “Evie,” which relies on towing for transport between locations. The vehicle’s onboard odometer and GPS, critical for tracking mileage and ensuring timely maintenance, were not powered during transit, resulting in inaccurate odometer readings. MTM engaged IMTRAM to develop a solution to keep the existing odometer and GPS systems powered without relying on an axle-mounted approach, as specified in the project brief.

This case study focuses on the restoration and refurbishment of 30-year-old Secheron UR26 High-Speed Circuit Breakers for KiwiRail. IMTRAM is the authorised Australian and New Zealand service center for Secheron; a world-leading supplier of High-Speed AC and DC Circuit Breakers, Contactors, and Switches. This case study outlines the process followed by IMTRAM to breathe new life into the Secheron UR26 Circuit Breakers, prolonging their operational lifespan.

In 2020 Yarra Trams was required to upgrade some obsolete components of their Combino BCUs. Some parts were no longer available and IMTRAM provided a solution with partner Hanning & Kahl to upgrade some components in the BCUs as opposed to replacing them completely. This saved costs as well as materials as only some components were required to be replaced to make the BCUs future proof.

With annual service reviews revealing battery failures and facing ongoing starting issues, the railroad was a perfect candidate for the trial. Battery life and starting reliability issues can result in huge costs for railroads, not to mention the time it takes to send people and equipment to diagnose and jump start a locomotive. It’s not a pleasant or safe environment for railroad workers. Now with the installation of ZTR's KickStart, those issues are no longer a worry, not to mention the environmental benefits of extending battery life.
