Digital Command Control (DCC) is a boon to model railroaders.  In it’s essence it is simple, straightforward, and user friendly [geekspeak for easy to use.] Nevertheless, several myths persist.  Those who use DCC  will chuckle at these, but many new model railroaders  find them confusing.  So without further ado, here, in no particular order, are the myths.

  1. Each locomotive will require a dedicated throttle. If I have five locos I need five throttles.   No.  Each operator will need a throttle, which can control any decoder equipped loco.
  2. DCC systems must be connected to a computer.  No.  The command station IS a single-purpose computer. It’s all you need to run your locos.
  3. Loco programming requires a computer.   No.  All basic programming can be done through the command station using the throttle that came with the set. You can use your computer for advanced programming, but it’s a “nice-to-have” and not a necessity.
  4. Older (pre-DCC) locomotives cannot be used.  No.  Any locomotive, be it 2-rail, 3-rail, DC or AC powered, can be converted.  Some will require more work than others.
  5. The track must be re-wired and existing control panels removed.   No.  Existing wiring can be  used.  If your control panels are set up for multiple cabs set them all to the same cab and attach the DCC system to the inputs for that cab.
  6. “DCC friendly” turnouts must be used.   No. If your layout runs fine with the current turnouts it will run fine on DCC.  All-rail turnouts are OK too if  insulated  rail joiners are properly used.
  7. Blocks are unnecessary.  No and Yes.  Conventional DC blocking  is overkill.  The wiring can be simplified into maintenance/troubleshooting sections. e.g.: A town with a passing siding and several spurs  can be wired as one section.
  8. DCC systems are not compatible with each other.  All DCC systems will talk to all DCC decoders, regardless of brand.  Generally, however,  the command station and throttles must be the same brand.

Finally, remember that this is technology, not magic.  If you’re using 2-rail  all the rules concerning polarity, reversing sections, and insulation must be followed. But fear not, for there are devices available to overcome these problems.
