Ultra Cab II provides real-time onboard reception of wayside signals for safer, more productive hauling of products. The system features a cab signaling receiver built on dual digital signal processing technology. The receiver can change filtering and response characteristics from one territory to another as easily as a radio changes channels. Ultra Cab II can be used as an onboard hub for advanced train control systems using track transponders, GPS receivers, and radios for radio-to-wayside communications.
