Power is provided to the tracks through the use of an individual track bus for each track. The track bus is normally 12awg cable with drops provided every few feet to allow connection to the individual modules. It is best to have at least one drop per track on each side of the standard 6' table. By keeping the track buses separate, the layout can be configured to run both tracks in DC mode, both tracks in DCC mode, or one track in DC mode while the other track is running in DCC mode.

Track Wiring - Power drops supplying current to the track are normally done by drilling a 1/2" hole under a rail joint on each track and replacing the normal rail joiners between those tracks with a Kato Terminal Unijoiner (part #20-818). Feed the power cords down through the hole to the bottom of the module, and the drop can be connected to the track bus when setting up the layout. Care should be taken to ensure that the blue wire is connected to the outside rail of each track, and the white wire is connected to the inside rail in the standard BWWB configuration. Failure to follow that standard will result in short circuits when connecting to other modules in a large layout.

Bus Cable - Each track bus is normally 8' to 10' in length terminated on each end with Anderson Power Pole connectors. The Power Pole connectors are placed vertically with each end having a different color on top. When using red/yellow and black connectors, the blue wires should be connected to the black connector and the white wires should be connected to the red/yellow. In the middle of the cable, connecting wires are added to provide connection to the power drops coming from the individual modules. Normally, there should be at least two connectors per cable, allowing for connections to each side of an 6' table. The connectors from the bus should have connectors to mate with the module track feed.
