Digital Command Control

The digital system uses only two wires for transmiting orders to the layout, the track. We can control locomotives, turnouts and signaling. The track voltage is diferent from an analog model railroad, here goes power and data according to NMRA standards.

This is my participation in the Charlas Ferroviarias (Railway Talks) organized by AMSG and AFCV

Going deeper into digital railway modeling. Part 1

This is an introductory book to the Arduino programming language applied to railway modeling as a result of a forum thread in CTMS

The main components of a DCC system are:


Command Station Accessory Decoder Loco Decoder Feedback Booster

The description and construction of each component is:

Command Station v.2D

Controls the model railway


Send power and data to the track

Loco decoder

Instaled on every locomotive controls its speed and lights

Function decoder

Adds supplementary functions or sound to a locomotive

Accesory decoder

Controls turnouts and signaling


Detects trains for automatic control


Bi-directional communications


Automatic control of the layout


Configuration Variables


Other kits for the layout
