The caption on that photo states "Headed south to Richmond station, train 92 passes this stopped freight."
Train 92 is a northbound train, so there's something incorrect about the caption. Analyzing the photo, one notes that the shadows are directly beneath the train, implying that the photo was taken around noon. Amtrak.com shows that train 92 (assuming he got "south" and "north" mixed up) arrived at 9:11 am. Train 91, the southbound version, isn't due until 5 pm, when it would be dark out.
However, train 89, the Palmetto, is due around noon, and Amtrak.com shows 89(2) as having arrived at 12:12 pm. Therefore, I'd say the photo is labeled wrong.
