DCC basics

Read NMRA facts about Digital Command Control and the store features that need a closer check.

Control each locomotive.

DCC means Digital Command Control. The NMRA beginner guide describes DCC as a way to control locomotives independently.

Read the exact DCC label.

The NMRA guide distinguishes DCC-ready locomotives from DCC-equipped locomotives. Check the maker page for the parts and installation each model needs.

Check sound features separately. A DCC label alone does not state that the model has sound.

Use the published standards.

The NMRA DCC Working Group develops and updates the DCC standards. Its page links to the electrical standards under S-9.

The NMRA page identifies CV8 as the manufacturer ID and CV7 as the decoder version. Read the decoder manual before you change settings.

Questions from the workbench.

Does DCC-ready mean a decoder is installed?

Do not assume this. Check the exact maker description for the decoder and installation requirements.

Does a DCC label confirm sound?

No. Check the sound features stated for the exact model.
