The C44-9W, part of General Electric's Dash 9 series, became a common freight locomotive for the Atchison, Topeka and Santa Fe in the 1990s, and its Nathan K5LA horn became one of the most recognised sounds in North American railroading. This recording circulates as a hornsound asset for Trainz, the train simulator, and through VRChat train builds such as Mikadolad's Trains. Shared by railfan creators and simulator players, it survives online as a compact, authentic horn sample for virtual routes and train videos.
