Through the years, the shape and colors may have changed, but electric trolley buses are Metro's original "zero-emission" coaches and remain a vital part of Metro as we continue our transition to a zero-emission fleet.

The current generation of electric trolleys are:

Good for riders

• Ability to go “off wire” means the bus can get around problems on the road and keep you moving!
• Passengers can open the backdoor when the bus is at a stop—no need to call out to the driver.
• More seats and standing room make the trip comfortable for more people per ride!
• Air conditioning keeps everyone cool.
• Low floor makes it easier and safer to get on and off.

Good for neighborhoods

• No exhaust equals cleaner air.
• Quiet operation eases the noise of city streets and neighborhoods.
• Lighter weight so there's less impact on the roads.

Good for the environment

• These energy-efficient all electric vehicles use 30 percent less energy than the existing trolleys.
• Zero emissions help fight climate change.
• Regenerative braking sends energy back into the trolley electrical system.
