I saw an ad for their line of products for control of locomotives and turnouts. At first glance it seems quite well done and simple to use. Do any of you have any hands on experience with this system? I'm curious how it works and how do the locomotives sound? Does anyone know if you can combine their "decoder" with the sound side of say a Tsunami? Their system seems familiar somehow-is it perhaps like some of the European ("plug and play")Systems?
