The new Oak Cliff streetcar made its way across the 103-year-old Houston Street Viaduct Thursday night, about 59 years after the city’s old streetcar system ran its last car.

DART is testing the cars, which arrived from the manufacturer in Pennsylvania last week, and service is expected to begin April 13.

Ours is the first battery-powered streetcar in the United States — it runs on battery power from one end of the Houston bridge to the other.

Initially, the streetcar will run 1.7 miles from Union Station to Methodist Dallas Medical Center 5 a.m.-7 p.m. Monday-Friday. But there are plans to extend service. Extensions to the Bishop Arts District and the Dallas convention center could come online as soon as 2017.
