UNTIL THE EARLY 2000s analogue, or DC, control was the only choice for a model railway. It was and still is a simple, reliable and affordable means of providing control for a railway – and across all the scales.
A DC layout controller regulates the voltage to the track between 0-12v. Only one train can be driven on a circuit at once with analogue in most circumstances, but separate controllers can be connected to separate circuits – or sections – to allow independent control of multiple trains. If you do have more than one train on the same section of track both will move at the same time.
