Аннотация к книге "Direct traffic control"

High Quality Content by WIKIPEDIA articles! Direct Traffic Control (DTC) is a system for authorizing track occupancy used on some railroads instead of or in addition to signals. It is known as "direct" traffic control because the train dispatcher gives track authority directly to the train crew via radio, as opposed to through wayside personnel via telephone or telegraph, as in train orders.
