Hi Dmonky,
Saginaw Elevator kuid 2:50567:109908:1 has a built in unload track with room for a load track to be added, for that use a BI2 Grain Track kuid 2:30671:27220:1 and configure it. There is a Ground-grill Unloader Kuid 2:86311:45154:1 for a more realistic effect when unloading.
You can make the elevator larger with the Saginaw Extension Spline Kuid 2:50567:277351. ( it loads into the spline window of the building flyout in Surveyor)
Another very good unit used by Phil Skene in his layouts is the Alexander Grain Facility Kuid 58223:2705. You need to add the above tracks to this one though.
Cheers
Mike
