Abstract
An automatic toll ticketing system was cut into service in Las Vegas, Nev., on November 22, 1964, providing some services never before available. The general purpose relay used in this system embodies imaginative new concepts in. device design and application. The ESK relay was supported by several other highly reliable devices produced by Siemens & Halske, including EMD motorswitches and impulse repeaters. A new cordless operator position was developed to reduce both operator work time and possibility for error. Several auxiliary consoles were used for traffic administration, observation, and operator training.
