I have an undecorated version of the above locomotive, with on-board DCC and sound. From the box, the sound responds to the throttle setting as expected, but the loco has two speeds, stop and full speed ahead, even on speed step 1 (of 128).
Any idea what I could do to correct this?

I would check CV 2 to see what it shows, and change it to zero if there is a number there, and see what happens. My guess is that when changing something (like the loco ID no.) someone may have accidently put something in CV2 that's making it go full blast even at speed step 1.
Might not hurt to be sure CV 5 and 6 are zero also.
