I had been dissatisfied with the old locomotive roster, which put most of the locomotives in a three-digit series of some kind. After adjusting the overall, system-wide mileage for the KY&N, I realized that I actually needed to increase the size of the overall locomotive roster. Once the roster was adjusted for size, it no longer made since to keep the whole roster in three digits. I only have a handful of units numbered, so I may as well make the change.
After going through several versions of the roster inspired by the Chessie System, Chicago and North Western and the Southern Railway, I settled on this new roster.
Like many roads in the 1970's the oldest first generation locomotives were at or near the end of their service lives. Many of the F units are on the dead line, some of which would be A large contingent of GP7's and GP9's which effectively ended the steam era on the KY&N continue to soldier on after 20 plus years on the job, nearing the necessity for a significant rebuild program. A large order of new GP40-2's is on the horizon, which will eventually cause the retirement of most of the ALCO's on the roster by 1980.
