Locomotives and self-propelled scrap vehicles are remotely controlled via radio at the Burns Harbor plant of Bethlehem Steel Corporation in northern Indiana. Remote control equipment and systems including the retarders at the Burns Harbor plant were designed and furnished by the General Railway Signal Company. The GRS radio remote control system is capable of controlling as many as 128 vehicles, each up to 16 commands, simultaneously on the same radio frequency, without interference. Transmitting range is kept down to approximately half a mile to further minimize interference. The 154 MHz signal is transmitted in the form of random pulses, at the rate of one pulse during each 100 millisecond period of time. This technique practically eliminates the possibility of two simultaneously-transmitted pulses blocking one another.
