Digital Model Railway Control System Basics
Digital control systems provide the ability to independently control all aspects of operating a model railway using a minimum of wiring, the rails themselves can be the only wiring required. Control is achieved by sending a digital signal as well as power down the rails. These digital signals can control all aspects of the model trains and accessories, including signals, turnouts, lighting, level crossings, cranes, turntables, etc.
Constant power is supplied to the track and digital signals are sent which require electronic decoders to be fitted to locomotives and other devices to interpret the commands.

Famous quotes containing the words model, railway, control and/or system:
“If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.”
—James Mcneill Whistler (1834–1903)
“Her personality had an architectonic quality; I think of her when I see some of the great London railway termini, especially St. Pancras, with its soot and turrets, and she overshadowed her own daughters, whom she did not understand—my mother, who liked things to be nice; my dotty aunt. But my mother had not the strength to put even some physical distance between them, let alone keep the old monster at emotional arm’s length.”
—Angela Carter (1940–1992)
“We as a nation need to be reeducated about the necessary and sufficient conditions for making human beings human. We need to be reeducated not as parents—but as workers, neighbors, and friends; and as members of the organizations, committees, boards—and, especially, the informal networks that control our social institutions and thereby determine the conditions of life for our families and their children.”
—Urie Bronfenbrenner (b. 1917)
“Psychoanalysis is an attempt to examine a person’s self-justifications. Hence it can be undertaken only with the patient’s cooperation and can succeed only when the patient has something to gain by abandoning or modifying his system of self-justification.”
—Thomas Szasz (b. 1920)
