Welcome to the Hornsource! We are just starting but our hope is to provide people with a channel to provide information on what horns are on what locomotives and have one to place to find that out.

Here is a list of horns and what bells they have.

PS: I am actually a railfan many of you know. I'll let you figure who I am.

Our goal is to provide railfans with easy to find information on a particular locomotive and what horn it has. Again, we are just starting, but it will be big eventually.
