Southern Railway Class A-7

The A-7 Class were a fleet of 175 0-6-0 steam locomotive switchers that worked for the Southern Railway from 1904 until 1954.
== History ==
At the turn of the century, the Southern Railroad was a new company with a lot of older engines, this was also the case for switching locomotives. The switch engines at the time were the A-1, A-2, and A-3 classes. There was a need for some new switcher locomotives and the Southern came up with a new standard design to replace them.
In 1904, Baldwin built the first 24 engines of the new A-7 class locomotives. Each locomotive had 50" inch driving wheels, 20" x 26" inch cylinders, weighed in at 73 tons (117.87 tons with tender), a boiler pressure of 185 psi, and a tractive effort of 32,710 lbs. Their tenders could hold up to 7 tons of coal and 7,000 gallons of water.
Between 1904 and 1914, 175 locomotives were built by Baldwin, ALCo (Richmond, VA and Pittsburgh, PA Works), and Lima. Southern numbers were 1614 - 1751, AGS numbers were 6510 - 6518, CNO&TP numbers were 6015 - 6020, GS&F numbers were 8370 - 8375, and engines #8550, #8551, #8555 and #8556 worked at the St. Johns River Terminal. Engines #1614 and #1615 were built in 1907 by ALCo-Richmond for the Nashville Terminal Railroad (original numbers 3 and 4) back when the Southern controlled the Tennessee Central Railroad along with the Illinois Central Railroad. After the TC went back into private hands in 1908, the engines were renumbered to 1614 and 1615.
These locomotives could be seen almost anywhere on the entire Southern system working at big passenger terminals such as Chattanooga, Tennessee; Knoxville, Tennessee; Cincinnati, Ohio; Atlanta, Georgia; Spencer, North Carolina; Birmingham, Alabama; Alexandria, Virginia; New Orleans, Louisiana; Jacksonville, Florida; Sheffield, Alabama; Macon, Georgia; Asheville, North Carolina; Winston-Salem, North Carolina; Memphis, Tennessee; Nashville, Tennessee; and other major cities the Southern served.
Until the As-10 and As-11 class 0-8-0s arrived in 1914 and the 1920s, the A-7 class 0-6-0s were the primary switching locomotives on the Southern Railroad. In 1934, #1639 was the first of the class to be retired from service and after that, 19 more engines would be retired until 1939. After World war 2, retirements began again with engine #1621 in March 1946. One by one, all of them fell to the scrapper's torch and by the end of 1953, only one, #1655, was left. This engine would later be sold for scrap on December 28, 1954.

== Accidents ==
* On January 2, 1910, engine #1670 derailed and landed on its engineer's side in West Yards in Knoxville, Tennessee. Engineer William Hagues was killed.
== Sale to other companies ==
In October 1947, engine #6513 (formerly CNO&TP #113) was sold to the Tennessee Products & Chemical Company of Nashville, Tennessee.
In 1952, engine #1643 was sold to the Morehead & North Fork Railroad in Kentucky as their #12.
== Preservation ==
In September 1952, #1643 (built by ALCo-Pittsburgh in September 1905) was sold to the Morehead & North Fork Railroad Company as their #12. She hauled local clay products, coal, and lumber to the Chesapeake & Ohio interchange in Morehead, Kentucky for the M&NF until the railroad bought a pair of ALCo S-1 to replace their steam locomotives on April 1, 1963. 
The M&NF was abandoned in 1973, but a private owner took possession of the railroad and continued operations for his clay plant with four Baldwin diesels acquired in 1976. C&O successor CSX Transportation removed its track into Morehead during 1985, and for a while, the landlocked line operated the occasional steam-powered—and then diesel-powered—tourist trains until 1995. Steam sisters Nos.11 and 14 were sold and preserved elsewhere (and even operated), but 0-6-0 No.12 was shoved into the M&NF’s ramshackle shed in next-door Clearfield, and largely forgotten about.
In 2011, the locomotive was sold to Jerry Jacobson and it reached the Age of Steam Roundhouse in 2012. On July 16, 2018, the locomotive was finally restored to operation.
