Examples

“For use with petrol-electric, and subsequently diesel-electric, vehicles, air horns were developed about 1918, and today they vary from single-note instruments to those producing as many as five chiming pitches.”

“At a later date in production, the Western Region requested that the two-tone air horns should be placed on the cab roof instead of behind the buffer beam, in order to increase audibility.”

“37424 had been noted at Barrow Hill with its air horns moved onto the nose (in front of the cab windows) to allow it to work on certain routes where '37s' with roof-mounted horns are barred, such as to Stranraer. However, the horns have now been refitted to their normal position, with the bolts of the alternative positioning still fitted.”
