Zipcar, an international car-sharing network, will announce details of its expansion into downtown Kansas City at a news conference on Monday.

The company plans to add eight vehicles to four locations in downtown. Mayor Sly James and City Councilman Jermaine Reed will join other city officials and Zipcar representatives in front of Union Station at 3:30 p.m. to provide details of the new service and specific locations. Residents, students and local business representatives are invited to attend.

Zipcar already has two cars at Kansas City International Airport and two more at the University of Missouri-Kansas City. While the company has declined to provide details about demand for those cars, it has said the expansion downtown is indicative of the performance so far.

The locations are expected to be along or near the downtown Kansas City streetcar route from River Market to Union Station. Supporters of the service have touted it as a way for some people to jettison their cars. People can ride the streetcar downtown in the morning, take Zipcar to locations all over the city during the day if needed, and then return the cars to their location.
