It might surprise some that the name Air Line was applied to this community in 1856. It seems way ahead of its time. But “air line” actually referred to a type of railroad with straighter routes and therefore, in theory, quicker travel times. The Georgia Air Line Railroad was established in 1856 and ran through this section of Hart County, where a village and post office were established to support the enterprise. It was a modern innovation by 1850s standards and a vast improvement over earlier less consistent lines. Today, a busy store still serves the area, and this freight warehouse and the old elementary school survive as reminders of an earlier era.
