This was originally the Lionel WM Freight Set, 6-11749 (Service Station Set), featuring Diesel, caboose, and 6 hoppers, 2 black with coal loads, and 4 gray with hatches. All hoppers are consecutively numbered. Diesel and caboose were parted out, and the additional 2 pack of black hoppers with coal loads was added. MTH caboose was added. There is NO locomotive. I don’t remember if this set was ever run, so I’ll call it LN, instead of MOB. $250, plus actual shipping in set box.
