New York City Transit Authority is completing the installation of its two-way radio system for the subways. The system was designed to operate in the subways where radio transmission has always been a problem. A special two-way radio antenna was designed for the tunnels. The antenna has two wires separated by an air core in polyethylene insulation with an elliptical cross section. This design provided a significant reduction in installation costs. The heart of the system is the Transportation Command Center at the Brooklyn headquarters. When completed, the communications system will permit motormen and transit police to communicate with their command centers from any point on the 237 mile system, except for a few tunnel areas. The average monthly tally of communications for rapid transit and police is nearly 130,000 messages.
