PECO Track Basics

PECO logo

PECO track & accessories are the perfect choice for the serious modeler. The PECO brand is known for unsurpassed quality & reliability. The following tutorials & videos will assist you in setting up a layout using PECO products.

Cucamonga Trains stocks PECO code 55 & code 80 N gauge track as well as code 75, code 83 & code 100 HO gauge track:

The following pages feature N gauge flexi-track & turnouts:

The following pages feature HO gauge flexi-track & turnouts:


Flexi-track:

Flexi-track bends to make curves & can be cut to length.

Turnouts:

Turnouts can be controlled by either:

Cobalt turnout motor or Peco PL-10

Insulfrog vs. Electrofrog :

Insulfrog:

  • The frog area of the turnout is insulated
  • Simpler to wire
  • Not available in N gauge code 55 or HO gauge code 75

Electrofrog:

  • To wire frog polarity use PL-13, PL-15 or Cobalt
  • If using the Cobalt Turnout Motor - DCC Concepts recommends using only electrofrog turnouts with the Cobalt

Additional resources:

  • Article with detailed instructions for wiring turnouts on a DCC layout
  • Video (below) explaining in detail difference between Insulfrog & Electrofrog turnouts:

PECO N Gauge Code 80 vs. Code 55:

  • Code 80 - the rail sits on top of the tie & the entire height is exposed (rail height is .080")
  • Code 55 - the part of the rail visible above the tie is .055" but the rest of the rail (which is about the same height as the code 80 rail) is sunk into groves cut into the ties thereby giving the rails additional stability.

Preparing PECO Electrofrog turnouts for use with the Cobalt Turnout Motor:

The following alteration to the PECO Electrofrog turnout is recommended by PECO for all DCC applications:

PECO turnout preparation

  1. On the backside of the turnout locate the wire attached to the frog area. This wire will be connected to the common terminal of the Cobalt.
  2. Remove the 2 wires linking the center rails.
  3. Solder wire links between center and stock rails as shown in diagram.

Wiring PECO Electrofrog turnouts to the Cobalt Turnout Motor:

PECO turnout wiring diagram

Attach the wires

  1. The frog (green in the diagram) should be wired to the common terminal (C) on one of Cobalt’s built in SPDT switches.
  2. The rails (blue and red in diagram) should be wired to the other two terminals (S1 & S2) on Cobalt SPDT switch.

Now, when you change the turnout, the polarity of the frog will change to match the route and you will have perfect running!
