Frustrated with the LOUD sound the LC and LC+ is set to default, I searched a while to see if you can adjust it. You can! The manual doesn't tell you this with the set, but I found this: https://www.manualslib.com/man...-Mikado.html?page=14 and it worked!
"The overall volume of the sounds in your locomotive can be adjusted, but this requires the use of
the LionChief remote (in remote operation mode). To enter Volume Control Mode, place the remote
on a flat surface. Using one hand, press the WHISTLE and BELL buttons simultaneously. After three
seconds, the remote's red LED will begin to flash, acknowledging that you are in volume adjustment
mode. Keep the WHISTLE and BELL buttons depressed.
Using your other hand turn the speed control knob up or down to adjust the volume to your prefer-
ence. Release the WHISTLE and BELL buttons to exit volume adjustment mode"
Hope that helps those who want to adjust the volume on LC/LC+ locos.
