QL Lithium Battery Rail Grinding Machine Successfully Deployed in Australia

By QL Railway Machine | Oct 24, 2025

The QL Lithium Battery Rail Grinding Machine was recently deployed on the urban light rail lines in southern Melbourne by Loram Transit, one of Australia's leading rail maintenance contractors. The machine was selected to address strict night-time noise restrictions and reduce downtime during track maintenance windows.

During the first week of deployment, maintenance crews reported that the machine completed approximately 800 meters of rail grinding over two night shifts - work that previously required three shifts using conventional diesel-powered grinders. Operators noted that the machine's battery-powered design allowed them to work quietly and without emissions, making it easier to meet city noise regulations and continue operations safely at night.

Field engineers also highlighted the machine's portability and compact design. According to John Smith, a senior track maintenance engineer at Loram Transit, "The unit is surprisingly light for its capacity. We can move it quickly between track sections and set it up in minutes, which significantly improves our workflow and safety on site."
