Here's a look at my completed installation with a new Soundtraxx Econami ECO-100 Diesel decoder. Note that there is enough room left using the Econami and my Sweet Sound speaker that I included a Soundtraxx Current Keeper. I used a take-out board from a DCC ready locomotive to make the installation a little tidier. Far superior sound and it includes the braking function so the locomotive operates like a real one; apply throttle to get the locomotive moving, apply the brakes to get it to stops. Incidentally, the Econami comes pre-loaded with a choice of 5 different prime movers; EMD 567, EMD 645 turbo, EMD 710, GE FDL16 (modern version) and Alco 244, 16 different horns, and 4 different bells.
I can't wait to install one of these Econamis into my Rounhouse 2-6-0. Are these much smaller than their TSU-750. I think Soundtraxx has superior sound and motor control.
