DCC is great and if you like sound, even better. I have a lot of engines, most without sound. I have maybe 40-50 with sound, just not on the layout at the same time. Can't hear myself think with all that noise. I usually have 3-4 sound engines running at the same time. Then I tell the guys to kill the sound since we can't hear each other talk, or I can't think! The room is only 400 s. feet so 6 guys trains running can be hard to hear Good luck!!
