2-6-6-2 Articulated USRA

Standard design based on N&W Y-2 Mallet compound locomotive.Unlike the light articulateds, these engines were considered a great success. Alco (20 at Richmond and 45 at Schenectady) and Baldwin (15) built 80 of these, including 50 for the N&W as the Y-3, 20 for the Virginian, and 10 for the Clinchfield Railroad.
