Metro’s Battery-Powered Proterra Buses Now Running Revenue Service

King County Metro Proterra Catalyst

On February 17 Metro held a press event to announce that their three all-electric Proterra Catalyst battery-powered buses would be hitting the streets in revenue service that day. The buses will operate on routes 226 and 241—two routes that operate in a loop from the Eastgate Transit Center through downtown Bellevue.

Initially 4602 was entered service at Eastgate at 11:25 but it later broke down completely at Bel-Red Rd & 124 Av NE about an hour later. A diesel hybrid was brought in to replace it, and three hours later a mechanic brought out 4603 to run the rest of the trips for that run.

I rode route 241, and when it arrived at Eastgate TC it had used just 48% of its capacity after running a complete 18 mile loop of almost two hours. The layover time between these two trips is just 12 minutes. Since charging takes approximately 10 minutes and is required after every loop, this may mean that the trip will leave late if there are schedule delays on the incoming trip. Metro has not built in any additional layover padding next shakeup.

The “docking” process of the vehicle pulling in to the charger is almost completely automated; the operator simply holds the go pedal down and the bus takes care of forward acceleration. When the charge is complete, the arm automatically retracts.

The interior layout is designed to maximize seated capacity, with three seats being wedged in transversely between other rows of seats in order to make maximum use of space. The rear door is a passenger-activated plug door–the doors slide parallel to the body rather than pivoting. The rear section features a rear window and will soon be the only vehicles in the fleet to do so.
