Locomotive Roster for the Louisville & Nashville (L&N) Railroad

Louisville & Nashville (L&N) Railroad

Below is a diesel locomotive roster for the Louisville & Nashville (L&N) Railroad, organized by manufacturer and then by model. This roster includes the number of units the L&N owned for each model, including those acquired through mergers, particularly with the Nashville, Chattanooga and St. Louis Railway (NC&StL) in 1957. There are numerous websites, books, and archived reference materials that include the details of each locomotive.

Notes

  • Mergers: The L&N’s roster expanded considerably through mergers, with notable acquisitions from the NC&StL in 1957, the Tennessee Central in 1968, and the Monon Railroad in 1971.
  • Rebuilds: The L&N was known for its in-house rebuilding programs, converting older units into “slugs.”
  • Legacy: In 1982, the L&N, along with several other railroads, was absorbed into the newly formed Seaboard System, which eventually became part of CSX Transportation in 1986. Many of these locomotives continued to serve under these new corporate banners.
