I wish I could say this is my layout, but it isn't. This is the Carnegie Science Center's Minature Railroad and Village in Pittsburgh Pa. I have visited this thing since the early 70's when it was the Buhl Planetarium. An awesome O-gauge set-up which covers from the turn of the 19th century through the depression. All four seasons are depicted. Night and day transpires by light effects. I love this place and it has inspired me for decades. check out the pictures. I have more if you enjoy them (about 300) I don't want to go crazy here as to cause problems with sites banwidth allocations.
