Diesel Locomotive Roster of the Norfolk and Western (N&W) Railway

Below is a diesel locomotive roster for the Norfolk & Western (N&W) Railway, organized by manufacturer and then by model. This roster includes the number of units the N&W owned for each model. There are numerous websites, books, and archived reference materials that include the details of each locomotive.

Note: The N&W was a notable holdout for steam power and did not fully dieselize until 1960. Their diesel roster was initially small and primarily comprised of EMD GP9s. The roster expanded significantly following the 1964 merger with the Nickel Plate Road (NKP), Wabash Railroad (WAB), and other smaller lines, which added a large number of secondhand diesel locomotives, some of which were later rebuilt by the N&W. 

Electro-Motive Division (EMD)

  • GP9: The backbone of the N&W’s early diesel fleet, purchased in large numbers for both passenger and freight service. The passenger versions were equipped with steam generators and were often known as “redbirds.”
    • Number of units: ~416 (includes original N&W units, plus inherited NKP and WAB units)
  • GP18: Following their large GP9 orders, the N&W acquired the updated GP18 model.
    • Number of units: 48
  • GP30: An early second-generation road switcher acquired by the N&W in 1962.
    • Number of units: 44
  • GP35: Continuing to acquire new EMD models, the N&W purchased a significant number of GP35s.
    • Number of units: 40
  • GP40: In the mid-to-late 1960s, the N&W acquired a number of GP40s, all built with the distinctive high short hood.
    • Number of units: 60
  • GP38AC: These reliable units were purchased in the early 1970s.

    • Number of units: Inherited (NKP) 

American Locomotive Company (ALCO)

  • C420: The N&W received a number of C420s from the Nickel Plate merger.
    • Number of units: 8 (NKP)
  • C425: These were delivered to the N&W shortly after the 1964 merger, though originally ordered by Wabash.
    • Number of units: 17
  • C628: In the mid-1960s, the N&W acquired a number of C628s.
    • Number of units: 30

    • Number of units: 40 (VGN)
  • H-24-66 (“Train Master”): A small number of these were inherited from the Virginian merger.
    • Number of units: 13 (VGN), later rebuilt into slugs. 

General Electric (GE)

  • U25B: A few U25Bs were inherited from the Wabash merger.
    • Number of units: Inherited (WAB)
  • U28B: These were among the N&W’s early GE acquisitions.
    • Number of units: 30
  • U30B: Purchased in the late 1960s and early 1970s.
    • Number of units: 75
  • U30C: Acquired in the mid-1970s.
    • Number of units: 3
  • C30-7: The N&W purchased a significant number of C30-7s in the late 1970s.
