The Peco streamline Unifrog combines the features of both Insulfrog and Electrofrog.
As supplied the turnouts operate like an Insulfrog: the tip of the frog is a separate, isolated section,
so will be dead when connected to a live layout.
However, a wire has been welded to the underside of the frog tip that gives the modeller the option of
"powering" the frog, i.e. connecting it to a microswitch, or changeover switch, which allows the frog tip
to change polarity according to which direction the turnout is set. It's a much more versatile option for modellers.
All Peco Streamline turnouts are supplied complete with comprehensive instructions.
