At least nine American cities have built trolley lines through the central business district or downtown pedestrian malls in recent years. The city of Kenosha, WI, completed the Electric Streetcar Circulator Project, a two-mile line connecting the central city, METRA commuter rail station and Harborfront Park.

In Memphis, TN, the Main Street Trolley is a 2.5 mile line that interconnects the Central Business District, Main Street Mall, and several Memphis Landmarks. The Trolley began operations in 1993, and annual ridership had almost doubled by 1998.

In San Francisco, CA, a highly successful six mile streetcar line through the central business district was introduced in 1995 (F - Market Street).

Other cities with new streetcar systems include Dallas, TX (McKinney Avenue), New Orleans (Riverfront), and San Jose, CA.

In addition to Kenosha, systems are under construction in Colorado Springs, CO, Portland, OR, and Little Rock, AR.
