Conyers' Steam Locomotive Under a shed near Conyers’ 1898 depot is a 1905 Rogers 0-6-0 locomotive, the "Dinky," that once served the nearby Milstead Railroad as its No. 104. The engine, said to be one of only three of its type remaining in the world, was built by Rogers the same year that the company was acquired by ALCO. Conyers, the county seat of Rockdale County, is off I-20 about 25 miles east of Atlanta.   Georgia's Railroad History & Heritage. Copyright, Steve Storey.
