Competing Systems
In Europe, Selectrix is an open NEM standard, but the Märklin Digital system is proprietary. From the US, the Rail-Lynx system provides power with a fixed voltage to the rails while commands are sent digitally using infrared light. Other systems include the Digital Command System and Trainmaster Command Control.
Several major manufacturers (including Roco and Hornby and Bachmann), have entered the DCC market alongside makers which specialize in it (including Lenz, Digitrax, ESU, ZIMO, Kühn, Tams, North Coast Engineering (NCE), and CVP Products' EasyDCC, Sound Traxx, Lok Sound, and Train Control Systems). Most Selectrix central units are multi protocol units supporting DCC fully or partially (e.g Rautenhaus, Stärz and MTTM).

Famous quotes containing the words competing and/or systems:
“In a sense that I am unable to explicate further, the proponents of competing paradigms practice their trades in different worlds.”
—Thomas S. Kuhn (1922)
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
