Analogue DC control is simple to understand and use. The controller unit supplies up to 12 volts DC to the two rails of the track, with power being collected by the wheels of locomotives to supply the motor. Altering the setting of the controller adjusts the voltage and thereby the speed of the train and reversing polarity reverses the trains' direction.
One controller can be used to supply several locomotives or trains, however all trains will run and stop at the same time. When a second circuit of track is added another controller is required to run the circuits separately. Isolating rail joiners or isolator tracks can be used to make sections of a layout which can be switched off, allowing additional trains and locomotives to be stopped or stored in sidings while another train is running.
These controllers are suitable for gauges N, OO, HO and O and for all manufactuers' trains.
The alternative control system is DCC Digital Command Control which uses an on-board microprocessor fitted to each train. Offering a wide range of functionality including sound systems DCC is worth considering for a new layout. Please call us if you have any questions.
