Wiring Specifications

Wire Sizes

As with N-Trak, Bend Track uses no smaller than 18 gauge lamp cord for mainline power and no smaller than 16 gauge lamp cord for the 12 volt white power line. Since the modules are double sided, you will have six cords running across the underside of the module. At the ends of these cords, Bend Track uses the same two pin Cinch-Jones plugs that N-Trak specifies. For the feeder wires, use 22 to 24 gauge solid core wire to tap power from the orange/blue mainline cords to the rails. See FIG #10a. Bend Track also uses the same method for observing the polarity of both mainline and white line cords. The ribbed wire is connected to the wide pin of the Cinch-Jones plug and to the front rail of each mainline. 12 volts is carried by the wide pin of the Cinch-Jones plug and the ribbed wire and ground is carried by the small pin and smooth wire of the white cord.

Position of Wires and Plugs

The orange/blue cables should approximately follow under the appropriate mainlines, much the same as they do on any N-Trak module. Since the Bend Track module is like having two N-Trak modules which are connected back to back, you will have six wires hanging down on each end of the module instead of N-Trak's 4 wires. Refer to FIG. #10b.


The front rail should be soldered to the ribbed side of the lamp cord which is then soldered to the wide pin of the CINCH JONES plug. Repeat this process for all mainline connector plugs.



If possible, at the ends of the module, the orange/blue cords should remain close to the outside edges under the appropriate mains. The white cords should remain close to the center. This will keep them in line when the modules are clamped together and keep the white 12 volt lines away from the mainlines to reduce the chance of 12 volts getting plugged into a mainline. Be sure to leave at least 6" of cord below the bench work on both ends. This will allow an adequate amount of cord to plug into the next module.

Referring to figures 9, 10, 11, and 12, note that an easy way to remember where the male and female Cinch-Jones plugs go is to notice that as you view a Bend Track module from the side (not from an end), the right hand end always has the male plug and the left hand end always has the female plug. A "T" module has three sides but the "right hand rule" still applies as you look at each side by itself. The right hand rule for the gender of the Cinch-Jones plugs guarantees that any module can be rotated any way and still connect to other modules that have not been rotated.

Balloon Wiring

Balloons have a small change to the required wiring. Since they only have one end to connect, they need less cords than a standard end. The only cords needed are the orange/blue cords to feed the mains. The white cords are optional on balloon modules. This is because the white male/female Cinch-Jones plugs at the outer end of the last non-balloon module of the branch can be plugged into each other to make the continuous connection for the white line. At this point the purpose of the white cords should be mentioned. They serve the same purpose for Bend Track as they do in N-Trak in that they provide a 12 volt power supply which we can tap off of for use on mainline throttles, yard or local cabs or anything that needs 12 volts of power such as lights, signals, etc. A DPST (double pole, single throw) or DPDT (double pole, double throw) switch or some kind of disconnection must be included for BOTH CONDUCTORS of the white line if you are using power from it for your module so that if problems arise, the switch can be shut off to isolate the problem from the rest of the white line. A properly sized fuse is also a must!


If thought of properly, Bend Track wiring is identical in concept to that of N-Trak with the exception of one less mainline and the use of different color codes.
