About the sound
The signal horn from the 1950s was part of the work equipment used by a shunter for the industrial railway at the Henrichshütte Ironworks in Hattingen. It served as a warning horn when trains approached and was also used for communication between the shunter and the signal operator or the train driver.
In more recent times, it has found a place as an exhibit in the LWL-Industrial Museum's collection.
In order to produce a sound, the shunter blew air into the mouthpiece. The air was directed along a small metal plate, which vibrated in the process.
The sound thus generated exited the horn amplified by the trumpet bell.
