I too am one who replaced my sound decoders with Tsumani's but thankfully I only had 2 engines done VBG.

I now have 6 with 2 more to do VBG

I just love the Tsunami's, sound and control.

While we are discussing engines, how about the SR&RL #24 a OF 2-6-2 . Even though it is a 2' gauge engine it would still go well in On30 and B-nam's cars.

NCE DCC,

Since I was into CTC16/32 and Dynatrol in years past, when I built my HO layout several years ago I started from the beginning with DCC and when I converted to On30 a year+ ago it was a natural progression all with sound of course  .
