Safe and reliable PTC operation

Trainguard Sentinel consists of a primary control module and cab display unit, with an option for a second display unit. Speed and location are determined by an on-board track database, a commercial GPS receiver, and axle tachometers. Trainguard Sentinel provides integrated head- and end-of-train operation. It also uses AAR interoperability standards to create open interfaces to data radios or other locomotive equipment.
