Шаблон:Short description Шаблон:Infobox locomotive
The Ingalls 4-S was an experimental American locomotive built by Ingalls Shipbuilding immediately after World War II. Intended as the first of many Ingalls-built locomotives, it was the only one the company built. It served on the Gulf, Mobile and Ohio Railroad (GM&O) until it was retired in 1966; it was scrapped the following year.
Design and development
At the end of World War II, Ingalls Shipbuilding, based in Pascagoula, Mississippi, developed plans for a line of diesel-electric locomotives to serve the expected post-war market. Five models were projected; the first, and as it proved only, to be built was a prototype of the largest, the model 4-S.[1]
A single demonstrator was planned in December 1945, and built in March 1946, numbered #1500. The design of the locomotive was considered advanced, including a "turret cab" arrangement, which improved the crew's vision.[2] The prime mover selected for the locomotive was the inline-8 65LX8, based on a marine diesel engine built by Superior Engines & Compressors; and modified for railroad use by Cooper-Bessemer, and Elliott Company providing the turbocharger. The 4-S produced Шаблон:Convert, of which Шаблон:Convert was available for the production of tractive effort by the locomotive's electric drive, but marketed as 1,500 horsepower.[1] Provision was made for the installation of a steam generator for passenger service.[2] The locomotive was equipped with connections for multiple unit operation.[3]
Operational service
The 4-S demonstrator was tested by a number of railroads, including the Louisville and Nashville, Seaboard Air Line, Mississippi Export Railroad, Gulf, Mobile and Ohio, and the Southern Railway; however no orders materialized for the type, or for any other of Ingalls' proposed locomotives.[2] The lack of orders combined with issues with the supply of components resulted in Ingalls electing to abandon its plans for locomotive construction;[1] the sole 4-S was the only locomotive they ever built.[4] It was sold to the Gulf, Mobile and Ohio Railroad for US$140,000 in June 1946, where it received the road number 1900.[2]
The 4-S served with the GM&O, operating primarily from Mobile, Alabama, to Jackson, Mississippi, but also served around Meridian and Laurel. It was used in switching duty, earning a reputation for toughness;[1] it once derailed, landing inverted, but was repaired and returned to service in short order.[2] In 1966, the railroad traded it in to EMD as partial payment for new SD40s.[1] It was offered to the Illinois Railway Museum for US$3,000, but the museum was unable to raise the funds.[2] When no other buyers materialized,[1] it was sold to Pielet Brothers in 1967, where it was scrapped.[2]
