+ | The old way of connecting up a model railway layout was for every point and signal to have a set of wires back to the control box where switches were located for the operator to use. The idea of a layout control bus is to have a small number of wires (the bus) carry the instructions around the layout. Several different ways of doing this have been devised and some of them are described here. Using modern technology the switches can be implemented in a lot of different ways or even be replaced by automation. | ||
