This was updated before ERR offered Cruise but they did have a few innovative items.
The TMCC board is as small or smaller than a Cruise lite and Jon offered two one of kind sound boards. The were the scaled down Sound Commanders called the Beep Commander and the Buddy Commander. Pressing Aux1 2 with a Beep Commander would emit a beep beep roadrunner sound. The Buddy Commander was offered in single chime and dual chime horns. This is the dual chime. Sound Commanders only had horn/whistle, bell, and prime mover/chuff. No other sounds.
