General Locomotive Notes

- Retirement dates given are taken direct from Kennecott records. Kennecott shows this information as "PDA", for Property Disposal Authority.
- Roster compiled from information furnished by Kennecott. Additional information furnished by Ryan Ballard, Ken Ardinger, Allen Copeland, and Blair Kooistra.
