My bachmann 4-4-0 modern was stopping often on dcc with my digitrix 51 controller.  It would run fine on dc.  I changed back to my Bachmann e-z command controller and it now runs fine on dcc.  Does this make any sense. My broadway Limited E-8 runs better with the e-z command than it did with the digitrix 51. My atlas and intermountain engines run fine with either controller.
