In 1923, Swiss composer Artur Honneger (1892-1955) wrote a concert piece about the 4-6-2 Pacific locomotive, but he referred to it as the "Pacific 231", based on the wheels visible from one side.
He professed to love locomotives, especially the larger ones such as the Pacifics, calling them "living things" and honoring them as divine creations.
His music is largely unmelodic and atonal, but it does have dynamic changes indicating the increase in speed as the locomotive accelerates from start to high speed and back to a stop.
This 8-minute B&W film was made in 1949 as accompaniment to the music, showing plenty of side-rod action and shots of the fireman and engineer hard at work.
