The clip is credited to creator Jaymacnally and circulated among Trainz simulator players who share custom engine sounds for virtual locomotives. The P42 is part of GE's Genesis series, built for Amtrak passenger service and recognised by railfans for its distinctive diesel sound when departing stations. Short throttle recordings like this spread through simulator forums and soundboards because they can be dropped into gameplay captures without music or speech getting in the way. It remains popular with train editors who want an authentic American passenger locomotive cue in a single second.
About this sound
A short Amtrak P42 throttle sound effect by Jaymacnally for Trainz, capturing the locomotive engine notching up for train simulator edits and videos.
This one-second clip captures the throttle notch-up of an Amtrak P42 Genesis locomotive, the diesel passenger engine widely used on long-distance routes in the United States. You hear the low diesel rumble rise in pitch and intensity as power is applied, with a mechanical surge rather than a horn or bell. It is brief, clean and unmistakably industrial, making the start of movement feel weighty and powerful. Train fans use it to sell acceleration in simulator footage where the visual alone does not convey how hard the locomotive is working.
