Zimo fitted (hardwired, no socket) MX600 DCC. Very smooth runner including the crawl. The vertical motor as in all of this type has a little gear noise at higher unprototypical speeds. Kadee Couplers fitted. The rear is in an NEM box. The front pony has been modified to take a draft box type. Real coal in the tender completes the project. Great DCC fitted loco ready to go.
