  • This report describes the evaluation results for new Orion VII buses at NYCT with CNG propulsion and new hybrid propulsion.
  • This paper prepared for the 2005 American Public Transportation Association Bus & Paratransit Conference discusses the NREL/DOE evaluation of hybrid electric transit buses operated by New York City Transit.
  • Final results of the New York City Transit Hybrid-Electric Transit Bus Study. Hybrid buses had lower emissions, higher fuel economy, and higher operating costs compared with diesel buses. New York City Transit (NYCT), part of the Metropolitan Transportation Authority in New York, began operating the first of 10 heavy-duty diesel hybrid-electric transit bus prototypes (Model VI) from Orion Bus Industries in 1998. All 10 buses were in revenue service by mid-2000. The hybrid buses are intended to provide NYCT with increased fuel economy and lower levels of harmful exhaust emissions, compared with NYCT's diesel transit buses. Between 1999 and 2001more » (over various predefined fuel and maintenance evaluation periods), these first 10 hybrid buses were part of a data collection and analysis project sponsored by the U.S. Department of Energy (DOE). The operating costs, efficiency, emissions, and overall performance of these low-floor hybrid buses were compared against those of 14 conventional high-floor diesel transit buses (7 each from NovaBUS Corporation and Orion) operated by NYCT in similar service. Results indicate that the hybrid buses operate with greater fuel efficiency and much lower emissions, compared with the diesel buses. Maintenance costs for the prototype hybrid buses were significantly higher than those of the diesel buses during this evaluation. However, these costs are expected to decline for the next-generation Orion VII buses, currently being procured by NYCT, as repair technicians become more familiar with the advanced hybrid propulsion systems.« less
  • Paper describes the evaluation of hybrid-electric transit buses purchased by New York City Transit (NYCT) in an order group of 200 (Gen II) and compares their performance to those of similar hybrid-electric transit buses purchased by NYCT in an order group of 125 (Gen I).
  • The National Renewable Energy Laboratory (NREL) evaluated the performance of diesel, compressed natural gas (CNG), and hybrid electric (equipped with BAE Systems? HybriDrive propulsion system) transit buses at New York City Transit (NYCT). CNG, Gen I and Gen II hybrid electric propulsion systems were compared on fuel economy, maintenance and operating costs per mile, and reliability.
