This need to be implanted into your layout. Remember the coal must go somewhere(under the layout) or beside the
unloader. What you get is brass device only to keep the cost down for you. I mounted mine on the face of a pine board that will be secured to the layout. More pine board is used for mounting the track. A space is allowed for the coal to find its way through the rail and ties. Several ties are remover except two in the middle. I recommend Atlas code 83 or 100 be used as the spikes are sturdy and the center ties will not break loose.
