History

In 1947, the '' Silver Comet'' was introduced by the

Seaboard Air Line Railroad The Seaboard Air Line Railroad , known colloquially as the Seaboard Railroad during its time, was an American railroad that existed from April 14, 1900, until July 1, 1967, when it merged with the Atlantic Coast Line Railroad, its longtime ri ...

(SAL) during the height of passenger rail use. Due to declining ridership, the ''Silver Comet'' was downgraded in the 1960s, losing its sleeper-lounger cars. In 1969, the ''Silver Comet'' was downgraded again and finally discontinued in June of that year, by SAL successor Seaboard Coast Line (SCL). By 1986 SCL had gradually merged with several nearby railroads, forming the Seaboard System, which had become

initially purchased the former roadbed for future use as a high-speed transit route, but later that year, Ron Griffith, Director of Cobb County Parks, requested a lease agreement between the county and the Georgia DOT to use the rail line as a multi-use trail. The Cobb County Board of Commissioners approved the multi-use trail plan in November. Construction began in July 1998, with the initial section between Nickajack Creek and Hicks Road opening by that November. The former SAL/SCL right of way is rail banked. This means at any time in the future, if rail traffic increases to the point where an old line exists, it could be purchased and track put back down. The right of way would thus become a Class 1 railroad again. The former SAL/SCL line is 78 miles shorter than the line CSXT now uses, the former ACL, and Atlanta & West Point lines, which run well south of the former SAL/SCL line. In September 2019 the James M. Cox Foundation gave $6 million to the

, which will connect the Silver Comet Trail to the Atlanta Beltline. This project has been split into two parts. The PATH Foundation is responsible for the section from the current Silver Comet Trail terminus at the Mavell Road trailhead and then following the abandoned railroad right of way to Plant Atkinson Road. The Cobb DOT is responsible for the section from Plant Atkinson road to the Atlanta Road/Marietta Boulevard bridge over the Chattahoochee river, following an easement along Atlanta Road. Cobb expects to let its section for bid in Spring 2023. PATH's section is in flux due to legal challenges from railroad right of way easement holders.

Economic impact

In 2013, a detailed study was done on the trail to determine the economic impact of the trail. It was estimated that the trail had 1.9 million uses in 2013. 400,000 of those uses were from out of state. The direct spending of residents and tourists was $57 million. The $118 million economic impact was found to support 1,310 jobs. The tax revenue generated by the trail was estimated to be about $3.5 million in income tax, sales tax, and business taxes. The study suggested an 4 to 7 increase in property taxes for homes within a quarter mile of the trail, resulting in an increase of $0.5 million in revenue for municipalities and school districts.

Geology

In Paulding County, the Silver Comet Trail crosses over the Allatoona Fault; where the trail intersects the fault in the vicinity of Willow Springs Road, the fault serves to divide the distinctive Eastern Blue Ridge rocks from those that most characterize the Western Blue Ridge Province. One rock formation of particular note in Paulding County is the Ordovician-age Pumpkinvine Creek Formation (PCF), primarily composed of metamorphosed volcanic rocks thought to have originated out in the now-vanished, ancient ocean that geologists generally refer to as
