O Scale Transformers and Digital Command Control Systems
There are several ways to power your layout. Most starter sets currently have a transformer or remote control that will operate the train.
If you decide to add on to your layout, you may need to know the power options.
Conventional means a traditional transformer. The transformers runs on varying voltage, the more volts you use the faster the train runs.
Command Controlled means each locomotive is equipped with a "digital number" that only responds to signals meant specifically for it.The track is electrified at a constant voltage.The individual command-equipped locomotives can operated at low or fast speeds depending on what you tell it by way of a remote control wirelessly linked to a control box connected to the track. WIth this system, you can run multiple locomotives independently of each other.
The two digital command-control systems for O scale (O Gauge):
Both systems can be operated on the same track at the same time, and those desiring the most flexibility have equipped their layouts with both systems. For engines not equipped with command control electronics, both systems can operate conventional locomotives on seperate tracks, although with Lionel's Legacy systems you must purchase an additional box called the Power Master.
