Casper posted:i have an outer loop that is just a oval using 048 that is controlled with a cw80 transformer. The inner loop has some switches and is controlled by another cw80. I currently only have the power attached at one point of each track. I read that it is good to add power to the opposite side of the layout also. It also said it is good for your transformers to share a common ground, so would I only run one line to both outer rails of the loop or should I do one for each? Any information on this would help great, thank you all!
In your case, all is good as it is. The loops are separate, keep them that way. One feed is fine if the trains like it. Only add another if it is needed. Remember that the 8 driver Berk, like a Polar, will slow a little in curves (O36) from wheel bind and not power loss.
You could drop a second set of feeders if you are making the installation permanent, as in putting landscaping around the track and such.
