Double-decker bus
With the exception of coaches, double-decker buses are uncommon in the United States. Many private operators, such as Megabus, run by Coach USA, employs double-decker buses on its busier intercity routes.
Greater Dayton Regional Transit Authority
One notable feature of the GDRTA system is its use of electric trolley buses. Only five cities in the United States currently have electric trolley buses: Boston, Dayton, Philadelphia, San Francisco and Seattle. The first electric trolley bus (ETB) operation in Ohio occurred in Dayton, on April 23, 1933, when the Linden–Salem line was converted from streetcars to trackless trolleys — or trolley buses, as they are most commonly known today. The RTA renewed its commitment to electric transit with a Board of Trustees vote to continue the trolley bus service in 1991, and the purchase of a new fleet of ETBs from Electric Transit, Inc., a joint venture of the Czech company Skoda and the U.S. company AAI Corporation, based on Skoda's model 14Tr. Final assembly of the vehicles took place in Dayton in 1995–98. In 2014, the system added its first low-floor trolley buses, with four dual-mode prototypes purchased from Vossloh Kiepe (now Kiepe Electric) and using bodies from Gillig, for testing and evaluation. In January 2018, RTA placed an order with Kiepe for 26 production-series dual-mode trolley buses to the same design as the prototypes, with Gillig low-floor bodies, for delivery starting in 2019.
