Great picture; last I saw this was 1971 when it was a single track segment between Smith & Norwood. Then we called the 149 Paton Tank & the 147 Coon Hollow Dip. Had a 40MPH speed restriction back then for train handling purposes. Any train seperation (knuckle or drawbar) was serious then because it backed up the railroad at both ends, especially when the northbound parade was running during the late afternoon.
