LINCOLN, Neb. (AP) – Lincoln will soon see trolleys again after a more than 70-year absence.

The city’s public transit bus system, StarTran, plans to buy two compressed natural gas trolleys and three buses with a $2 million federal grant.

City transit manager Mike Davis says StarTran uses 13 compressed natural gas buses on its routes on the University of Nebraska’s campus and that they generate 20 percent less greenhouse gas than regular buses.

The new trolleys will have rubber tires and operate like a bus instead of riding on tracks or being attached to overhead trolley wires.

StarTran has issued a request for proposals for the trolleys, which will run on a route that goes through downtown. StarTran hopes to begin using them in early 2017.
