The company manufactures transit buses and intercity motor coaches. New Flyer delivered 911 transit buses in the second quarter, a 22% increase over the same period last year. The bus maker expects continued strength in the market, driven by the need to replace older buses, Sapp said. The average age of transit buses in U.S. fleets is 8.2 years, according to the American Public Transportation Association. The company defines a single 30-foot to 45-foot bus as one unit, and an articulated transit bus counts as two units.
