Update on my small shelf layout. Still playing with where what goes where. Have my double main line half way and some turnouts placed. I use Caboose hand throws ' I love those for shelf layouts. You will notice my Ethanol plant' That's where I will place it. Been gluing all the piping back together after storage. And you will see a tunnel entrance. It will be a Faux tunnel 'I will get some foam and build a small hill around it for effect' And one day it could go to another extension. All my engines all running perfect except one of my BLI GE Diesel's ' Junk. Have a lot of spurs to add and much track to lay. But the trains run great over all the no6 turnouts, One thing I love about code 100 is I hook up one feeder wire on the outer main line and the locos ran all over the turnouts to all the spots shown. I did add a few more feeders for insurance, code 100 really carries the signal for ever. Well thanks and comments welcome.
