    Default Am Trak

    Not sure if this has been mentioned yet nor if it even happens to anyone. This has happened to me for a total of 3 times now. When either trapped behind a railroad crossing or driving on a street next to a railroad I get K band false (sometimes instant on, somtimes just a weak alert) from Am-Trak (or whatever those fast people carrier trains are called).

    I get a K band warning here whenever I go by the Southern Pacific railroad.

    They use k-band radar for distance readings...

    Yeah it's similar to the old RASHID system.

    Default locomotives really do use radar

    Jimbonzzz is correct. Radar is used to monitor wheel slippage on diesel electric railroad locomotives. The onboard computer constantly monitors the ground radar speed and compares it to the axle-mounted speedometer. On modern locomotives, If the system detects a difference between the two, it will automatically reduce the amount of current being fed to the traction motors and will send a wheel slip alert to the engineer's console. On older models the system sends an alert to the engineer who then has to manually back off the power. Wheel slip leads to traction motor damage and rail burn.
