Kansas City, Mo. ? Kansas City Mayor Mark Funkhouser has unveiled a $1.2 billion rail-transit plan for the metro region.

The plan includes five types of transit services, including light rail and modern streetcars through downtown and a commuter train service for suburbs.

Funkhouser has been calling for regional mass transit, and the plan released Tuesday maps out new details of his idea. The plan affects a dozen suburbs on the Missouri side of the metropolitan area, but it excludes the Kansas side because authorizing legislation exists only in Missouri. Mayors in the Johnson County, Kan., suburbs have shown little interest for a transit tax.

Funkhouser is trying to get ballot measures passed in Jackson, Clay and Platte counties for a half-cent sales tax increase that would help fund the transit system.

He is scheduled to meet with other metro-area mayors and county officials Friday. Although a poll in the three Missouri counties showed that people would support a half-cent sales tax for mass transit, the questions did not include the specifics of Funkhouser’s plan.

If the regional concept doesn’t get enough support, Kansas City officials are prepared to ask voters in November to decide on a city-only light-rail starter route.
