Very heavy train, 7 diesel engines, 200 cars, 23,000 HP, 20,000 tons, Norfolk Southern, Atlanta, GA 

A very long NS - Norfolk Southern Railroad - manifest freight train with 7 diesel locomotives pulls out of Chamblee near Atlanta, Georgia, for about 160 cars, then stops, pushes back, adds on more cars and after more than an hour finally leaves with about 200 cars.
I watched this train from the lawn behind Frosty Caboose in Chamblee, Georgia.
