I was just wanting to post some pictures of my "under construction" large o27 layout. Most of the time if you a post on o27 it is a 4x8 or smaller. My layout is 14x20 and adding a 4x16 addition. All my track is Lionel tubular and rubber roadbed. It is a open frame design. The mainline is a 3 time around pass going up and down grade two level setup. In the middle of the peninsula I have an o54 switch back operation for a logging and minning industry. Here are some random pictures I have taken and I'd like to get some feedback on them. Thanks.
