Common Rail Wiring

Light gauge i use solid feeder wires would run short distances from the buss wire to a solder connection on the bottom or outside of the rail.

Common rail wiring. The common reference is supplied by an internal system common at 0v dc. Common rail wiring uses a single master heavy duty gauge wire that is shared by all electrical devices powering the layout as part of their common current path. When wiring blocks you can either cut gaps in both rails or wire one rail constantly and only cut a single rail. As the loco crosses the gaps a short on either rail can reverse a autoreversing booster no optional wipers needed.

Sometimes you have to jumper wire around a turnout frog and gap to do this. Hi guys and gals my third video going into detail on how the common rail and feeders work for my layout. One way of wiring a railroad is called common rail. Un common rail wiring is similar to common rail with the following differences.

All harnesses are tested for faults before they leave the factory floor. You wire the common rail to the terminals on both cab a and cab b terminals which are when their direction switches are set the same. I know i had some people questioning how it works. Please read entire manual before installation.

And cabs a b are both running the same direction according to their direction control switches i e the terminals of both packs are connected to the common rail. All components of this harness are new. Gaps are cut in both rails at each block boundary wires run from each isolated rail in each block to the control panel. This is called common rail wiring which works well for wiring signals with most blocks.

Install cummins common rail engine swap harness on the market. Here the common is not connected to either rail and will flow seamlessly right through double gaps reverse sections ect. Direct home run wiring with common power reference direct home wiring. Hopefully the diagrams shed some light.

You can use various types of model train switches for this project. This harness is designed for easy installation even if you have no electrical experience. The wire follows and feed the common. All the feeder wires from the common rail black wires can be connected to the one common power bus black that runs around your entire layout usually below the plywood base.

However the positive rail will have red feeder wires attached which will then go separately to toggle switches or slide switches on your control panel. Hello guy the buss wire would be a heavy gauge wire that carries the layout power around under the layout.
