The Kirkwood Subdivision is a present-day HO scale model railroad of a freelanced Union Pacific subdivision. Location is in Kansas and Nebraska. The basic layout is a loop-to-loop design with double track main lines connecting the loops. These loops are mostly hidden, and are the staging areas for transcontinental traffic at both ends.

At present, only the lower deck and peninsula are operating, which results in "loop- to-point" operations. These operations currently consist of running two unit coal drags with distributed power, and a " local" to switch cars at three customers.

The bench work for upper deck is about half complete. The two decks are not separate and joined by a helix, but instead, form a giant spiral around the walls. This  grade 'connecting' the two decks is 54 feet long with a 3.48% ruling grade.
