The locomotive that was used make this sound was Pere Marquette "N-1" class Berkshire type steam locomotive #1225, who runs at the Steam Railroading Institute in Owosso, Michigan. In order for the locomotive to make this kind of chugging sound, it hauled 12 hopper cars that were fully loaded with sand, to ensure that it would make some heavy chugging noises that the sound crews could use during post-production.
