Notes
⚠: Not Verified or Educated Guess
(1): Late production Centuries could be bought with Alco's two axle Hi-Ad trucks, boosting the adhesion to 29%.
(2): Later Centuries were offered with a different set of gearings, 66 MPH as a base speed and 74, 78, and 83 as options.
(3): Later Alcos had newer GE 752 traction motors, changing this rating to 1195 Amps.
