US-based Progress Rail Services has acquired Inspired Systems as part of plans to expand signalling offerings.
Headquartered in Canning Vale in Western Australia and with another facility in Port Headland, Inspired Systems currently offers asset protection and condition-based monitoring systems.
Its product portfolio allows operators to increase efficiency and improve safety of rolling stock assets.
Progress Rail Engineering and Track Services is a wholly owned subsidiary of Caterpillar. Its senior vice-president Dave Roeder said: "We’ve collaborated with Inspired since 2010, and they have made great strides to meet the needs of customers in the region, paying special attention to the rugged environment and creating products and services that can easily adapt.
"This acquisition is a natural fit for the Progress Rail family, as it expands our presence in the global signalling and communications segment.
"Inspired has reliable asset protection and condition-based monitoring systems that complement our existing offerings for the Australian heavy haul market, as well as worldwide railroad customers."
