Editing Digital Command Control (section)

==Competing systems==
There are two main European alternatives: [[Selectrix]], an open ''[[Normen Europäischer Modellbahnen]]'' (NEM) standard, and the [[Märklin Digital]] proprietary system. The US 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 model railway control systems|Digital Command System]] and [[Trainmaster Command Control]].

Several major manufacturers (including Märklin, [[Fleischmann_(model_railroads)|Fleischmann]], [[Roco (model railroads)|Roco]], [[Hornby Railways|Hornby]] and [[Bachmann Industries|Bachmann]]), have entered the DCC market alongside makers which specialize in it (including Lenz, Digitrax, ESU, ZIMO, Kühn, Tams, NCE, Digikeijs, and CVP Products, Sound Traxx, Train Control Systems and ZTC). Most Selectrix central units are multi protocol units supporting DCC fully or partially (e.g. Rautenhaus, Stärz and MTTM).
