Control systems and operation

Fig. 7. DCC controller. Wireless DCC throttles offer freedom of mobility for operating a layout.

Dispatcher control (cab control)To operate more than one train using direct current (DC) train control, a model railroad can be divided into a series of isolated electrical blocks. A dispatcher then assigns one or more blocks to an operator’s cab, allowing him to run his train in these areas. Memory throttleA memory throttle allows an […]
