Trivia[]

  • 4115 was delivered with a boiler designed to be pressed to 250 psi (17.25 bar) with a cutoff set to 68%. This combination of stroke length and boiler pressure yielded the same tractive effort as the others, but the piston load was calculated to increase by 15%. Other slight differences included a valve travel of 9 1/2" (241 mm), 1/2" (12.7 mm) longer than the valves in the others.
  • It was never used for passenger service.
  • This is one of 15 engines delivered in 1927.
