In one embodiment, a railroad scout vehicle system includes a scout vehicle and a processing unit. The scout vehicle may include at least two wheels configured to engage a set of railroad tracks, a motor mechanically coupled to at least one of the wheels, a speed controller, an electromagnetic sensor aimed at the set of railroad tracks, a positioning receiver, a local speed sensing device and a transceiver. The speed controller may be coupled to the motor and configured to control the speed of the scout vehicle in order to maintain an appropriate distance between the scout vehicle and a train traveling behind. The processing unit may be configured to transmit the track status information via the transceiver, receive train speed and position signals from the train via the transceiver.
