Norfolk and Western No. 2189 was one of 30 built Y6b class 2-8-8-2 articulated steam locomotives built at the N&W's Roanoke Shops sometime between 1948 and 1952 for the Norfolk and Western Railway. 
They were an improvement of the previous Y6a class with the only difference between the Y6as and the Y6bs was that the Y6bs were longer than the Y6as, had a larger firebox and had a greater tractive effort. With the Y6as only generating a tractive effort of 166,000 lbf (738.5 kN) and the Y6bs generating a tractive effort of 170,000 lbf (756.2 kN). The locomotives delivered 5,500 horsepower. The weight of a Y6b locomotive about 582,900 lbs with 522,850 lbs directly on the drivers. 
No. 2189 and most of the class were taken out of service between 1958 and 1961 and were all scrapped leaving no examples of the Y6b to survive into preservation.
