I have a 1956 Wabash 2367 F3 AB I believe was made early in the year using leftover St Fe frame, trucks and shell. As in the attached picture, the master carton is stamped with the "X" designation, painting is original as seen, and I understand I am second owner. Also have the aluminum dump car, 3rd Rail grey boiler SP cab forward someone mentioned earlier, etc.....
But, I believe the Wabash F# AB may be most interesting.

A lot of neat items there, but yes.....the Wabash is very interesting!
BTW, the 2367 was 1955 production. The single motored 2240 Wabash was 1956. Lionel seemed to really like that paint scheme....and so do I.
