Moving trains on city streets, that's street running. Where the rails are embedded in the pavement streetcar style, and not within a separate pathway, that's street running.
Georgia still has a few street runs. The best known is probably Sixth Street in Augusta (photo above), where Norfolk Southern trains roll eight blocks through the east side of downtown. Albany has Roosevelt Avenue, on the north side of downtown, and Columbus has Ninth Street, where trains rumble directly into the city core from a river bridge, just like in Augusta. Columbus also has the occasional train on Sixth Street between Front Avenue and Sixth Avenue.
In Sandersville, trains run down the middle of Tybee Street, a short street in a residential area northeast of downtown.
Among the lost street runs are River Street in Savannah, which ended around 2003, and Wayne Street in Milledgeville, where the last train eased through the middle of town in the 1960s.
Montezuma once had Seaboard Coast Line trains on Cherry Street downtown. For a photo, see Bernie Feltman's memorable shot at rrpicturearchives.net.
NS trains still travel through the center of downtown Commerce on a very narrow pathway with automobile traffic sometimes inches away, but it's not true street-running because the rails are not set into the street (see below.) A similar case of not-quite-street-running can be observed on Rome's Glen Milner Blvd.
