I'm just so happy with the way this is going, this being my first layout, I just have to show it to yall. I'm steadily making progress. Got quite a bit more track down. Have been running some trains and everything is doing well. I've got a #22 feeder up through the foam to every piece of flex track and the switches have feeders also. The feeders are tied to short pieces of #18 solid which are then tied to my #12 bus which extends all along the layout.
