The Irwin Group of Companies has strategically evolved into three major pillars: the Industrial Technologies Group, the Transit Group and the Mining Group. Each group serves as a testament to Irwin’s commitment to serving a diverse array of industries and business sectors, ensuring stability, growth and fostering innovation. Irwin’s Industrial Technologies Group and its business units remain a linchpin in the railroad, maintenance of way, metals, cargo handling, shipbuilding, automotive and aerospace sectors.

ITP and VECOM USA designs and manufactures its proprietary line of versatile T-3 track switches and signaling equipment. The acquisition of VECOM USA of Tampa has given Irwin the ability to provide comprehensive train to wayside communication systems, passenger and diagnostic information systems for light rail vehicles, etc. Irwin Car’s commitment to quality, customer service, and maintaining the shortest lead times in the industry have also helped make Irwin a go-to supplier for industries that can’t afford downtime, and all of Irwin Car’s products are Buy American compliant for rail and transit applications.
