Seaboard Air Line piggyback train TT-23 is rolling through the now suburban community of Raleigh, NC known as Millbrook. 3 GP-40's are in charge of the "trailer train" today which Seaboard operated as an extra daily except Monday. The rural highway crossing in the distance is now a 4 lane city thoroughfare surrounded by shopping centers, restaurants and housing, and the once busy Seaboard north-south mainline is now a single track, 58 mile CSX stub-end branchline.
