I have three of those AM Pacifics, two of mine are converted to TMCC/Railsounds to run on Legacy. They pull 6 AM Budd cars around the layout with no issue. This includes some 2.2% grades. I will say that consist takes at least 4A to run well. I have 10A supplies to each of 8 independent power districts around the layout. I do not use DCC so I have no experience with it, but regardless of the decoder and its settings my experience suggests at least a 5A supply dedicated to that track is necessary. I have 14VAC on the track. If the DCC output voltage is much less than 14V it may cause problems when the engine is loaded.
