With all the work on the new DDA40X, have you left any room for speakers or a sound decoder? With it's large body it's one of the few diesels really made to be heard in N scale.
Dear Geek,
I haven't had one apart, but I'll check when I get a sample.
Have fun!

Will this locomotive have a NMRA plug a circut bord or will the Decoder be hard-wired in?
