GREX is there when tracks wash out, when ties begin to break down, and when ballast needs to be replaced. We collaborate with customers to develop innovative solutions that solve their toughest rail maintenance challenges.

Together, we’ll find track flaws before they shut you down, pinpoint where ballast is needed and automate its delivery, monitor your bridges remotely, and empower you to work more efficiently. At GREX, we’re all in, all the time to deliver Real Rail Solutions®.
