      Hi,

      Rokuhan turnouts should be driven like dc motor controlled
      turnouts without end switches. This means the polarity of
      the dc power sets the direction and power should only be
      applied for a limited time. A 5V-6V dc pulse around 0.5-1
      second would probably work. Most dcc decoders that
      support dc point motors, variable voltage and pulse
      time could be used. Dcc decoders with continous output
      should be avoided, since they would burn the coils.

      best wishes: Viktor Kovacs

      ps: Any dcc decoder that works with N scale tomix turnouts
      could be used, just check the output voltage and drop
      the excess with multiple diodes in series or if supported,
      lower the output voltage on the decoder. Other than that,
      timing and programming should be the same.
