Need help changing Locomotive bells.

[Ausgebombt]

I know how to change a horn with no problem but I have two locomotives with no bells and every time I try to fix them, the bells don't work, its just silence. Can anybody tell me what to do?

You need to be a bit more specific on what locomotive you're trying to change, the sounds you're replacing the originals with, etc, in order for us to be able to provide assistance.

Cheers.

The engines i need help with are the F45 and the SW1500 that comes with the Marias Pass DLC. I want to put a steel bell on the F45.
