I loved the U28C model in HO. Had about 8 units from Rivarossi and ConCor(?) and AHM... So, I found an N scale version from Arnold/Hornby at a good price. I talked with Frank at ESU USA, and he said the 6 pin wired version of the Micro DCC would work. Just got the ESU decoder, #58816. I will print up a cabinet for the speaker next week, and put it together. Stay tuned.
