running backwards as the turnout motor switch reverses the con-
nection to the track. Understand, with DCC there will probably be a
bit of hesitation for the short period of time while the switch motor
contacts do not connect any power to the track.
In other reversing situations such as wyes, the use of switches tied to
the turnouts isn’t nearly as simple and, therefore not recommended.
Turnouts have frogs. That is the name for the blue segments in [1]
and [2] track work where the straight and diverging rails cross. It
must be either electrically isolated (Peco calls them Insulfrog) or
have its polarity change (Peco Electrofrog) depending upon which
direction the train is headed, straight or diverging. It is the right rail
in one case and the left rail in the other.
