  • July 30, 2020 | Allison Transmissions

    New York City Transit (NYCT) has ordered 50 Allison electric hybrid-equipped buses from New Flyer and Allison Transmission. Most of the electric hybrid buses will be delivered in 2021. NYCT maintains a fleet of more than 5,700 buses, 60 percent of which are equipped with Allison Bus Series™ B 400 and B 500 transmissions. “Our electric hybrid propulsion system offers New York City a considerable advantage,” said Rohan Barua, vice president of North America Sales at Allison Transmission. “Not only will these systems improve air quality, they are fuel efficient as well. New York City has indicated they will rely on Allison electric hybrids to reduce CO2 emissions in the city, while allowing the city to maintain a durable, reliable, economical fleet.” More than 10,000 state- and city-owned vehicles operating in New York are powered by Allison, according to the company.


  • July 27, 2020 | Edmonton Transit Service

    Edmonton Transit Service (ETS) and Proterra unveiled its first 21 Proterra electric buses and brand new, purpose-built electric bus garages. ETS has 19 more Proterra buses on the way this year to make up a 40-bus fleet, one of the largest purchases of electric buses in Canadian history. With this deployment, ETS also becomes the first to implement in-depot overhead charging on the continent. ETS will begin putting the electric buses into service in early August. Edmonton selected the 40-foot Proterra Catalyst E2 max vehicle with 660 kWh of onboard energy and the DuoPower™ drivetrain. The E2 max bus has six Proterra battery packs on board, enabling these vehicles to get approximately 218 miles of range on ETS routes. This vehicle model broke the world record for the longest distance traveled by any electric vehicle on a single charge, and ETS is the first customer in North America to put it into service. Featuring two electric motors, the DuoPower drivetrain delivers 510 horsepower, accelerating a Catalyst bus from zero to 20 mph in under six seconds. In addition, the DuoPower drivetrain can propel a bus up a 25% grade, making it an ideal option for routes with steep hills. To charge its new buses, Edmonton also unveiled the new Kathleen Andrews Garage, named after Edmonton’s first woman transit operator, who worked for the City for 23 years. ETS collaborated with the Proterra Energy™ team to install 26 ABB 150 kW depot chargers connected to inverted pantographs and seven 60 kW Proterra plug-in chargers in the maintenance area, all of which are interoperable and standardized.
