I call it my layout. I use O Gauge tubular track and O22 switch tracks.
I sometimes call it The Put because I like to add trains and features to it reminiscent of The Put (Putnam Division of the NY Central).
Mine is conventional with block wiring so I have independently powered 2 main lines and 8 sidings. I also have 16 O22 switches so it is an interconnected switching layout.
It is about 35 feet long and 3 and one-half to 4 feet wide, so I think that makes it a medium sized layout. It is also an around the walls long and narrow layout with backdrops.
An MTH Z4000 powers the 2 main lines, a ZW and KW power the sidings and accessories, and another ZW powers the 022 switches.
