I used custom sounds from the Roblox marketplace to make this video. Some sounds sound different because they are sped with the original horn or bell sound. How to do what I did. Step 1: Buy a private server for 50 robux. Step 2: use command ;supermode. Step 3: Put in a sound ID from the horn. Step 4: Open Roblox Studio and search for the type of train horn you want. NOTE: Some horns may not come up in search. Step 5: Look for the play button to have a preview of what the sound will sound like. Then highlight the numbers next to the word "rbassetid://". Then hit Ctrl C to copy it. After that then go to supermode and select the button that says sounds. Then hit Ctrl V to post the sound into horn or bell. That's it!
