Before CATS operated WiFi-enabled buses throughout Baton Rouge, transit service was provided by the Baton Rouge Street Railroad Company and consisted of a series of mule-driven trolley cars operating along Government Street. The service was upgraded 11 years later when the Capital Railway and Lighting Company used the first electric cars to transport people around town.

CATS has evolved from a private business to a political subdivision of the State of Louisiana created by special act of the Louisiana legislature. Over the years, names changed from the Baton Rouge Bus Company to Metro Transit to the present-day Capital Area Transit System.

CATS operated from its streetcar/bus barn near the intersection of Plank Road and Scenic Highway, and then from a location on Seneca Street. In May 1998, CATS built its administrative, maintenance and transfer facility at 2250 Florida Boulevard, where it operates today. In June 1999, CATS began operating buses seven days a week, 363 days a year.

In 2012, voters in the City of Baton Rouge and the City of Baker approved increased funding for the system, including an expansion of lines. In March 2014, CATS altered 20 routes and added 10 more using five transit hubs to improve efficiency and shorten ride times for passengers.

The agency continues to enhance its service with plans for new terminals and Bus Rapid Transit lines designed to intersect with the City of Baton Rouge’s long-term community development plans. The agency is embracing its role as one piece of a larger transit puzzle, connecting with ride-share and bike-share projects and planned tram service to deliver a seamless transportation experience in Baton Rouge.
