DART rail in the context of "Dallas Area Rapid Transit"

Dallas Area Rapid Transit (DART) is a transit agency serving the Dallas–Fort Worth metroplex of Texas. It operates buses, light rail, commuter rail, and high-occupancy vehicle lanes in Dallas and twelve of its suburbs. In 2024, the system had a ridership of 55,151,000, or about 162,900 per weekday as of the third quarter of 2025.

DART was created in 1983 to replace a municipal bus system and funded expansion of the region's transit network through a sales tax levied in member cities. DART rail began operation in 1996 and operates over 93 miles (149.7 km) of track. It was the longest light rail system in the United States until 2023, when it was surpassed by Los Angeles Metro Rail with the consolidation of the A Line.
