The Monon Route was a historic railway line in the United States, primarily serving the state of Indiana. It was established in the late 19th century and connected several key cities, including Indianapolis and Chicago. The route played a significant role in the transportation of goods and passengers, contributing to the economic development of the region. Originally operated by the Monon Railroad, the line was known for its efficient service and scenic views. Over the years, it underwent various ownership changes and eventually ceased operations in the late 20th century. Today, parts of the Monon Route have been repurposed as trails for walking and biking, preserving its legacy in the community.
