Even a micro-sized or unfinished pike can still provide reasonable operations and the easiest way to get started is the Inglenook Sidings puzzle. I've just completed the oval as described in a previous post and, while I haven't added the Fiddle Yard yet, I can still enjoy shunting a few cars thanks to this simplest of switching puzzles.
I put eight cars on the layout in groups of five and three. Then I shuffle them and randomly select an ordered group of five to comprise my train. Then all that's left to do is assemble the cut. Each session fills a fun half hour.


I use google sheets and select eight cars for the session. Then I simply shuffle their order using the randomize function. The first five (in order) is what my finished train should look like.
A note on the table: The notes that include "former" are cars I intend to repaint and letter in the near future. At that point the "MARKS" column will have their new road name and number.
