Here is a Kato 22-101-1 Sound Box Module. A sleek, plug-and-play analog sound module for N & HO-scale train layouts. Comes complete with an Early EMD 1st-Gen diesel sound cartridge. Built-in speaker reacts to your locomotives speed via back-EMF sensing so whistles, chuffs, and engine revs sync with actual movement, not a fixed throttle. Modular sound cartridges let you swap in different engine types (diesel, steam, electric). Includes stereo audio out for external speakers or headphones. Simple, immersive “in-cab” realism without DCC. Ideal for analog setups.
