100 years ago there were 250,000 miles of operational railroad track in the USA (and practically 4% of the adult work force was employed by a railroad). That's a lot of trains and schedules.   Each railroad had its own timetables and schedules. At that time, only about 5% of the railroad cars carried passengers.

100 years ago there were 46 states, and children who rode the "Orphan Train" were placed in all but one of these states. Therefore any one of the railroad tracks in these 45 states may have been traveled by "Orphan Train" riders en route to join their new families.
