Back in December, I posted that I was going to build a ceiling track. Well, I finally finished the last corner. Then, I finally mounted the last section giving me a complete loop. As you can see by the test cars, I have even managed to lay some track. I will be using DCC to run the trains on the two loops. Therefore, I dived into studying DCC wiring. This brings me to the reason for this post. The total length of the loop is about 64 feet. So… Am I okay running a continuous power bus along the loop? Or, am I better off using insulators and treating the track as a 64 foot long track with a snubber instead of a loop? I used my oscilloscope to measure the voltage drop on thetrack I have already put down. In the short section I have, there is already a 4V drop from end to end.Therefore, the need for a power bus is obvious.I am planning on using 12AWG for the power bus. I will also be running a separate bus for the track lights since there will be a lot of them. There are only two switch machines, so they will just be attached to the track power bus and controlled via DCC.
