The EMD GP16 is a series of rebuilt diesel-electric locomotives, a result of a remanufacturing program initiated by the Seaboard Coast Line Railroad (SCL) in an effort to spare the cost of purchasing new motive power in the late 1970s. This involved the rebuilding of their aging fleet of EMD GP7, GP9 and GP18 road switchers (many of which were over twenty years old). 155 locomotives (122 GP7, 31 GP9 and two GP18) were rebuilt by the SCL.

The program

155 locomotives were rebuilt by the Seaboard Coast Line. The vast majority of them came from Atlantic Coast Line, Seaboard Air Line and their subsidiaries (Atlanta and West Point Railroad, Charleston and Western Carolina Railway, Georgia Railroad, Western Railway of Alabama, Winston-Salem Southbound Railway); eight units came from Clinchfield Railroad (with one of them ex Nashville, Chattanooga and St. Louis Railway), not counting the six units rebuilt at Paducah; seven units came from the Louisville and Nashville Railroad (including four ex-Chicago and Eastern Illinois Railroad units). [2]

The required modifications took nine weeks per unit on average to complete. The rebuild work was done at the railroad's Uceta Shops near Tampa, Florida, with the engines, bogies and traction motors rebuilt at Waycross and Jacksonville. [2] The program resulted in a cost savings of almost 50% over buying new locomotives.

Included in the program:

Ancillary benefits included a lowered engine idling speed and increased fuel efficiency. SCL committed over 100 of its personnel to the conversion program. The first GP16 emerged from SCL's Uceta (Tampa) shop in June 1979 while the last was placed into service during November 1982.

In service

The rebuilt locomotives saw service throughout the system, engaging in a variety of duties from local switching to main-line freight hauling. Though SCL became part of CSX in the 1980s, the majority of the units remained active until 1992, when the bulk of the roster was retired and sold-off. Many GP16s remain in active service today on short line railroads around the country, far exceeding their 15-year projected lifespan.

In 1993, the United States Army bought a small number of GP16s from CSX, which led some people to think the Army built it. The locomotives were sent to Conrail's Juniata Locomotive Shops to be remanufactured under contract with the Army. When they were completed, Conrail put a GP9M plate on them. These locomotives are controlled by Woodward PGR type diesel engine governors.

<span class="mw-page-title-main">Beep (locomotive)</span>

The "Beep" is an individual switcher locomotive built in 1970 by the Atchison, Topeka and Santa Fe Railway at its Cleburne, Texas, workshops. Technically a rebuild, the Beep originally entered service on the Santa Fe as a Baldwin Model VO-1000. Following its successful CF7 capital rebuilding program, the company hoped to determine if remanufacturing its aging, non-EMD end cab switchers by fitting them with new EMD prime movers was an economically viable proposition. The conversion procedure proved too costly and only the one unit was modified. In 2008-2009, this locomotive was retired and stored operational at Topeka, Kansas. In May 2009 the unit was donated to the Western America Railroad Museum in Barstow, California.
