              Northern Pacific 4-8-4 eases out of the roundhouse and onto the 
              turntable, as it prepares for its next run. In the 1920’s, 
              the Northern Pacific Railroad needed bigger passenger locomotives 
              so it had its motive power department work with the American Locomotive 
              Company's design engineers to develop a new locomotive. They designed 
              a new locomotive with a massive firebox that was supported by a 
              four-wheel trailing truck. It was the first locomotive with a 4-8-4 
              wheel arrangement and it was called a “Northern.” Several 
              years later in 1934, ten Class A-2s were delivered to the Northern 
              Pacific from the Baldwin Locomotive Works. The 2650 was the first 
              locomotive in that order of Northerns. |
