I understand it is no longer DCS. Everything is saved, so if I chose to get a replacement board or get it fixed, it can be returned to it's original condition. It runs well with the rectifier, I have no problem with forward only. I was hoping for a simple fix to get the light and smoke to operate, but no big deal if it does not. For the price I paid, a big, good looking and good running loco is Ok.
