How Is DCC Different from DC?

Posted by on Dec 18, 2014 in Miscellaneous, Tony's Tips |

Multiple Train Control Using Digital Command Control

With DCC, train operation depends on the decoder installed in the locomotive. The track is powered by a command station and/or booster connected to a transformer. Each locomotive operates independently over the track. Several locomotives can be moving at different speeds and in either direction at any time on the same electrical section of track. Blocking is not required for train control. It’s easy to move engines around in the yards and park them close to one another without worrying about where the insulated sections are. It’s easier to operate trains in the wide open spaces, too! DCC lets you run your trains instead of running your track.

Digital Command Control will revolutionize the way you run your railroad and it doesn’t have to cost an arm and a leg. Whether you have an existing railroad or are starting a new one, DCC can work for you and let you run your trains the way you’ve always wanted!

Why DCC Is Better?

  • Simpler wiring.
  • Control 9999 engines with only 2 wires.
  • DCC voltage always present on the track to feed lights, functions, accessories.
  • Turnouts/signals can be controlled with the track.
