The TCS WDK-ATL-3 WOWKit is a complete, drop-in WOWSound installation engineered to fit a specific Atlas HO locomotive. Everything you need comes in the box, so even a first-time DCC installer can get clean, professional sound without guesswork.
Each kit includes a WOWSound decoder, a TCS motherboard with on-board Keep-Alive® for stutter-free running, a speaker with speaker wire and enclosure, and a motor mounting clip. The decoder carries TCS's selectable diesel prime-mover sound sets — EMD, Alco, Baldwin/others, and GE — so you can match the engine to your prototype.

What comes in the kit?
Everything for a complete sound install: a WOWSound decoder, a TCS motherboard with on-board Keep-Alive, a correctly-sized speaker, and a motor mounting clip — all engineered to fit the target locomotive.
Will it fit my locomotive?
WOWKits are model-specific. This WDK-ATL-3 kit is matched to a particular Atlas HO engine — confirm your exact model against the TCS WOWKit application chart before ordering, or reach out and we'll help you check.
Do I need any other parts?
No — the kit is self-contained. You'll just need basic install tools and a soldering iron for the speaker leads.
