The film "Trains at Hayes Station" showing trains passing through the station with stereophonic sound was filmed from the roof of the defunct Aeolian pianola factory just north of the station.
The kitten starts to play with the feather walking down the piano keyboard and the feather lands on the 'on' switch with the kitten presses and the then-revealed pianola begins to play, ironically it is playing a variation of "Kitten On The Keys" a song composed by Zez Confrey in 1921.
