DD2 2-B-B-2 #5800 on Test Run at Bellevue, Delaware
This is a PRR one-of-a-kind. This is DD2 #5800 hauling a test PB70 combine southbound south of Bellevue, Del. The DD2 was conceived as a dual-purpose locomotive with 5,000 horsepower. PRR built the lone DD2 in February of 1938, and although it was never duplicated, it worked until it was scrapped in the early 1960's. It served in freight service its entire life and, like the one-of-a-kind P5b, it did some time in Baltimore pushing trains through the Baltimore tunnels. The Delaware River and New Jersey beyond are in the background.
