This project is intended as a DIY solution for a DCC enabled/controlled turntable.

The Turntable
If you do not know what a turntable is, have a look at these pages:
The key parts of a Turntable are:
  • Turntable’s PIT (the hole)
  • Bridge (that is inside the PIT, and carries the track that the locomotive sits on when it is spun around the PIT to the desired track.)

The System

In order to control a turntable we have to consider the individual parts that may be required, and these include both electrical and mechanical parts:

Electrical Components:

  • The power that feeds the track located on the bridge
  • Motor Control (power to the motor to rotate the bridge)
  • Position detection and Speed Circuitry (direction and speed)
  • DCC Controller/feedback (DCC addressing)
  • There is no electrical connection between the track and the motor.
    (In other words, the two are independently powered and the TYPE of power does NOT have to be the same- this gives flexibility
