It's been awhile for anupdate. Here's what I've done. I've added more trees. I added 2 of the Atlas signal systems. They work nice! The picture is my Southern 2-8-0 Loco number 722 locomotive pulling a coal train. Now I only need a GP38-2 Southern and my Southern railroad trains will be complete. NOT the layout! Andy I see something in the picture I should mention about the signal on your left by the locomotive. The reason why it is green is because the power is off the track. If the train was passing by there with power to the track. The signal would be red.
