There is described in this paper a system of continuous signals operating within the cab of a railway locomotive. This system was developed in an effort to provide more reliable and safer signals than the common semaphore or light signals. The particular type of system is called the three-speed, continuous-control signal system. It has been adopted quite extensively by the Atchinson, Topeka and Santa Fe Railway System.
