The Dinky came to Conyers in 1948 when it was purchased by Callaway Mills for operation on the company's Milstead Railroad, a 3.3-mile industrial line that connected the Milstead Plant textile mill to the Georgia Railroad in Conyers.
The mill closed in 1960, but the Milstead community around it survived, as did the Dinky. In the 1970s the locomotive was moved to the Georgia Agrirama, an outdoor living history museum in Tifton (now the Georgia Museum of Agriculture and Historic Village). It was moved back to Conyers in 1983 where it was put on display to commemorate an important part of the community's history.
In regard to the name "Dinky," industrial and yard engines were often given this nickname, most likely because they were significantly smaller than road locomotives.
Conyers, the county seat of Rockdale County, is off I-20 about 25 miles east of Atlanta.
