Kato HO/N 22203-2 Sound Card, EMD 2nd Generation Diesel with Turbocharger

Appropriate for multiple Diesels, such as the SD40-2, SDP40F, MP36PH and more!

Works with both HO and N track - The modular pass-through design of the Analog Sound Box means that it can easily be used for both N and HO scale!
Choo-choo-choose your sounds - The Analog Sound Box will ship with an included Early EMD 1st Generation Diesel sound chip, but additional diesel, steam and electric sound sets will be available (sold separately) that will allow you to bring nearly any sounds that you desire to your non-DCC layout!
Smart Back-EMF reading - The sound box doesn't just make noise - it will read the strain on the motor in your engines and know how fast they're moving and how hard they're working. Certain sound schemes (like steam where the chuff is directly linked to the visual movement of the side rods) will self-adjust the sound based on the speed of the locomotive so what you hear will match what you see, all without the need for DCC!
As loud (or as quiet) as you want it - Have a powerful home stereo system? Or maybe you'd prefer headphones so that you don't wake the neighbors- unlike sound systems that are tied to a locomotive, the Analog Sound Box has a stereo out port so you can connect headphones or speakers of your choice!
