The goal of every company is to provide its employees with a safe, accident-free work environment. We at A&K feel one way to do this is to provide your crew with the "CrewGuard Early Warning System." This advance warning system is like no other system on the market today. Through state of the art technology, it can provide a visual and audible warning of approaching trains or equipment to those working on or near live railroad tracks. This system gives your crews adequate time to get out of harm's way and provides them with an added margin of safety around active railroad tracks. Whether a Class I railroad, transit system or shortline, this product is a must for you.
