The Dallas Transit System (DTS) was a public transit service operated by the city of Dallas from 1964 to 1983. DART was created on August 13, 1983, as a replacement for DTS and funded the expansion of the region's transit network through a sales tax levied in member cities.

DART Light Rail began operation in 1996 and has grown to become the longest light rail system in the United States--at 93 miles long!
