So the next question for Rich is DCC or DCS?
Would you prefer models that are DCC ready?
I bought a couple of MTH older EMD models (SD45 and SDxx?) to convert to 2 rail when there wasn't many RTR available. Of course right after I bought them, a bunch of RTR 2 rail versions were available. I really wish the MTH sound sets had more turbo sounds in them when appropriate.
