QUOTE It seems that the first time you use the horn you only press the button once to turn the horn function on. For all second and subsequent horn use you have to push the function button twice to turn the horn function off and back on again. This actually varies from loco to loco. I have a few which operate like this and some where every touch of the appropriate function button triggers the sound. All the decoders are Loksound so they must be set this way for some reason.
