SP AC12 #4294 (the class of SP AC cab forward most likely responsible for the recording).

This is an extremely rare sound effect that can be found on the Standard Sound Effects Library, which is found under a company named Standard Radio Transcription Services Inc. The whistle heard in this sound effect is a Southern Pacific 6 chime whistle said to be from a Southern Pacific AC-12 cab forward class steam locomotive. However, this fact is still up for debate.

Sound Effect Description

Two long blasts from stationary steam engine.
