Lionel did make a "Wabash Train" the box name on it was "Iron Horse Freight" Lionel number is 6-11703. I think my dad bought it 1987/88. Only reason I think that, there is a Lionel Authorized service stations listing for 1987-1988 in the box. It probably was run for less than an hour when dad had it, I got it in 2011, oiled & lubed, powered up and it ran like a brand new engine.
