I have a GP9 New York Central Diesel engine. The box states that it has a horn. I looked at the engine and there appears to be one at the bottom of the chassis. I remember trains having horns that ran on batteries but this doesn’t appear to use one. My transformer is a Tech II Trainpower 027 and although it has a “whistle” switch, it doesn’t appear to do anything with the horn. This is a pretty heavy weighted car, although it’s a nice engine.
How can I test the horn? Is there a way I can test it if my transformer doesn’t make it sound?
