American Railway Association

The American Railway Association (ARA), founded in 1888, was an industry organization that helped coordinate and standardize practices among U.S. railroads. It aimed to improve safety, efficiency, and interoperability across different rail companies by establishing common standards for schedules, track gauges, and signaling. The ARA also contributed to the development of industry codes and safety regulations, fostering cooperation within the rapidly growing railroad industry. Though its influence declined over time, the ARA played a vital role in shaping the early development of American rail transportation.
