The photos (you might need to register to see them) include a DES3100 loco. These were built in Czechoslovakia by CKD Praha as a tropicalised variant of their T669.
There are also pictures of yellow machines, and a T-55 tank on a flat wagon.
From what I remember the Iraqis had pretty good track with concrete ties. I even got to see one train travel over the rails. It was one engine and about twenty covered hoppers
