KANSAS CITY, Mo. (AP) — Kansas City's new $100-million streetcar system faces potential delays that could mean it won't be ready in time for next March's Big 12 men's basketball tournament. Mayor Sly James has said it's crucial that the new two-mile downtown streetcar system can carry passengers in time for the March 2016 tournament, which is expected to draw thousands of visitors to downtown Kansas City. The streetcar track work is completed, and the electrical wiring is expected to be ready by the end of September. But City Manager Troy Schulte told The Kansas City Star on Tuesday the four streetcars, which together cost about $18 million, may not be finished until the end of the year, and that may not be enough time to start the service in March.
