30 years ago when I wired up my layout I didn't do it the conventional way. I wired from the transformer into a lockon, then from that lockon to the next lockon and so on completely around the loop. Loops are 8' x 20' and I used 6 lockons per track. I'm currently wiring in 2 more tracks using a main wire then feed off of it to the different connections, same as I saw on Lionel instructional video.
My question is what are the drawbacks of going lockon to lockon like I did originally? I've never noticed problems with operation of the trains. I was considering rewiring the original loops when I wire in the new ones.
