I purchased all the stuff I would need to put a sound decoder in one of my older Kato RS-2's many months ago from Tony's. And a couple speakers since.   Here is what it all looks like. Confusion is my only excuse for waiting to do this.

Hello, I just installed a Tsunami 2 sound decoder in a P2K  GP7.

I read and re-read the Technical data sheet about the 3 point speed table and it's very complicated to understand the Bit Values.

I want to adjust  -CV2: Start Voltage; CV3: Acceleration Rate; CV4: Deceleration Rate; CV5: Voltage High and CV6: Mid Voltage.

Now to enable theses CV's I read that I have to configure CV29 to a certain value.

That's where I got lost in the Bit Values.

Okay, so... I've been working with one of my Norris engines (the "Pegasus", though I could use my LaFayette if I have to... but they are identical either way)

I know they can be converted to DCC, because I've seen it done... and I do have some N scale decoders in the drawer (it seems "N" will fit better) but I haven't a clue what I'm doing, or how.

I am planning right now to have mostly switching track serving an urban industrial area and also a small yard. I want that cinder ballasted look of yards and old misused industry trackage. It doesn't make sense to me to use cork roadbed. Subroadbed will be sheet plywood by the way. Should I simply lay track on the plywood? Would there be any profile and if so what would I use? I have heard of using N scale cork but that would leave a gap in the middle which would eat ballast would it not?
