Direct current (DC or "continuous current") is the constant flow of electric charge. This is typically in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams.
Direct Current (DC)
Electrical current which flows only in one direction. Model railroad power packs for two-rail trains typically input AC (household) current, and convert (rectify) it for output as low-voltage DC current to run the trains.
Direct Current
Electrical current that flows in only one direction. Used for control of most model railroads before command control.

Direct Current - there is a measurable positive (+ve) and negative (-ve) charge, this is the 'traditional' way of powering model locomotives, either by 2 or 3 rail systems, or by overhead cantenary. DCC systems are based on an AC supply.
A direct current (or DC) motor is an electric motor that operates using electricity from a direct current (as opposed to alternating current, or AC). DC motors find use in a number of applications, including automobiles.

DC : Direct current. Electric current of constant polarity as supplied by batteries or from AC supplies via a rectifier. This is the power source for most model railways today but may well change in the not too distant future.
Current-DC--Direct Current. Most scale and hirail equipment operates on direct current offering smooth operation. By reversing a switch on the control panel a DC engine will reverse instantly.
In comparison to DC (Direct Current), AC can be transmitted long distances with little loss of voltage, and can easily have its voltage transformed.
Most model trains run on direct current (DC) just like the lights and radio in your car. These trains use the two running rails to carry the power to and from the train.
A different kind of O trains are Direct Current (DC) powered, two-rail trains. These trains require a lot more room for the wider curves, have different couplers and are more like enlarged HO trains than classic O gauge.
On the Chicago Sub side the 1500 volt direct current wires from the neighboring Metra Electric line emit radio frequency (RF). Sometimes this RF will create interference with the communication link between our head and tail end telemetry devices.
Can motor: a permanent magnet motor enclosed in a metal "can" (housing). A can motor is generally direct current (DC)-only.
Inverter Electronic power device mounted on trains to provide alternating current from direct current. For more information see the Electric Traction Pages Page.
