Origins of the curved object and the curve should stay at the same coordinates (i.e. move together). When you offset one relative to the other, the results would look weird as you can see.
So in this case, if you want to move them both either
select both and move
or 2. parent track to the curve and move curve (the track would follow now)
or 3. move curve in the Edit Mode (that way the origins stay in place)
