DCC Controlled Signals

This is a working pair of signals based on the Digitrax TF4
Quad Function Decoder.  The signals get power and control
information directly from the track - no need for unsightly
wires running across the layout.  The signal units can be
broken down for transport.  Most of the light gray elements
are glued together to protect the wiring; however, the
6x6 base plates are not glued to the signals so that they
can seperate easily in the event of a wayward hand or foot.

Questions & comments welcome,
