The diagram and supporting installation notes help the user to successfully include this kit in your steam engine. This is a Royz Trains product developed for use with the ERR electronics. The biggest advantage is to allow fully synchronized smoke and chuff sound. We also offer a smoke unit that gains full smoke output at 8.5 VAC track voltage.
With this item installed, even the basic AC or DC Commander will operate with the Sound board in sync with the smoke chuff! In addition, the sound kit chuff switch can be wired to operate both the smoke generator and the sound kit simultaneously.
