On Bill Navigato's Chicago, Peoria & Southern, some planning was required to get the desired results. At the far end the aisle is six-feet wide, allowing for crews to manuevar easily. Planning for a busy Peoria Yard (lower left) meant no switching would be done directly above or across, to keep operators at a minimum in the area. Long distances between towns was planned to allow for more realistic operation. In addition to planning track and benchwork, locomotives and rolling stock were chosen after planning for not only correct for the era, but also for anticipated traffic on the CP&S.
