Sunday Video: Trolleybus Technology Makes San Francisco’s Transit Superior

Stephen Fesler - April 06, 2025

Battery-electric buses have been increasingly foisted upon transit agencies around the country despite their nascent nature and growing recognition that battery-electric buses — at least at this stage of development — are a serious threat to reliability, service delivery, and the agency bottom line. But there’s an electric bus technology that has existed for almost a century that continues to go untapped at scale. Alan Fisher of Armchair Urbanist dives into how San Francisco is ready-made for electric trolleybuses and has a robust network of them today — just like Seattle — and why they’re better than battery-electric buses. With a little effort, San Francisco could widely expand electric trolleybuses with strategic investments to almost every corner of the city, Fisher shows.

Are Trolleybuses Being Forgotten in Metro’s Rapid Transition to Battery Buses?
Carrying nearly 20% of King County Metro boardings, the trolley fleet has been a workhorse of Seattle transit for 84 years. But oddly, trolleybuses have not been a focal point of Metro’s plan to electrify its fleet.
