This Pack can be used for the ALCO FA, DL109, UP GTELs, and EMD BL2. Included are enhanced A200 horns, respective bells, along with fixing a long time audio issue of train horns coming from the rear of engines.
Instructions can be found in the folder.
EDIT: A Second version has been added for louder bells to specific locomotives. The original is suppose to reflect on how loud the older engine were, making the bells a bit hard to hear. But if thats not your thing, get the Bell Fix version.
