Digital control supplies constant power to the track with the power being switched many times a second to provide the "bits" of data (0 and 1) necessary for control (such digital power is neither DC nor AC).
Any train lighting will vary in intensity with the power and be off when the locomotive is stopped. With analog systems fine Control of locomotives requires knowledge of the individual characteristics gradients and curves require constant adjustment and low speed running is both difficult and liable to stalling. All accessories such as signals and turnouts require individual switches and cables, making wiring very complex. For multiple controllers the layout must be divided into sections isolated from each other and each with its own controller and current supply. For multiple trains sidings must have a switch to isolate trains standing there and leave the track dead. Conventional analog control of model railways works by varying the track power and any locomotive on the track will respond by running at a speed roughly proportional to the power. The control system was released in Europe in 1985 and made available in the USA in 1986 under the name Digital H0.

It consisted of a full system including locomotive decoders (based on a Motorola chip), central control (Marklin-6021), a computer interface (Marklin-6050), turnout decoders (Marklin-6083), digital relays (Marklin-6084) and s88 feedback modules (Marklin-6088).
Excerpt: Marklin Digital was among the earlier digital model railway control system.
