The Callahan Subdivision is a CSX Transportation railroad subdivision within the Jacksonville Division on the former Seaboard Air Line Railroad. The sub extends northward 20 miles from Baldwin, Florida, where the Jacksonville Terminal Subdivision's S Line and Tallahassee Subdivision meet just north of Baldwin Yard, a classification yard. According to Jacksonville Division Timetable Number 4 published in 2005, the sub runs from milepost SM-0.18 to milepost SM-20.0, where it joins the Nahunta Subdivision, a former Atlantic Coast Line Railroad, in Callahan, Florida.
