The line was owned by Georgia-Pacific (GP) which had purchased and refurbished 35 miles (56 km) of an abandoned branch line to provide service to a GP oakwood mill in Gloster. The GLSR operated four or five freight trains per week until the plant closed in December 2002. One year later, Genesee & Wyoming acquired three short-line railroads from GP. However, this sale did not include the GLSR.
In September 2004, GP announced that they would re-open the Gloster oakwood mill. However, they did not continue to operate the GLSR. The McComb Enterprise Journal reported on April 2, 2008, that the Georgia-Pacific Corporation is closing its railroad and that the town of Gloster was interested in the rail bed.[1]
The Gloster Southern Railroad applied to discontinue service on its entire line in December 2009,[2] and crews began removing the railway and roadbed. By June 2013, it was reported that all of the track had been moved and sold for recycling.
