A simple mod to remove ALL train sounds associated with the Toy Train sets.
Removes the train emote sound and the sound the Toy Train Set makes. The only downside to this is that you won't hear any more genuine /train sounds. But until Blizzard tones down the train set I'm willing to make that sacrifice.
Instructions: Unzip the folder into your /World of Warcraft/Data/ folder, not your addon folder. What this does is tell World of Warcraft to use the provided BLANK files instead of the original files that are located in the Speech.MPQ file.
