Stationary (or Accessory) Decoder controls stationary accessory devices such as switches and building lights.

Stationary decoders cost between $50 and $85. Some control more than one accessory and some allow you to use either slow motion (Tortoise™ type) switch machines or solenoid (Atlas Snap type) switches.

If you want to build these yourself, printed circuit boards and instructions are available from the DCC Working Group.
