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 only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
