A Shift Towards Electric Buses

Public transit agencies across the United States are increasingly adopting battery-electric buses. However, many transit authorities are facing challenges that threaten their reliability, service delivery, and financial sustainability. Amid this transition, a long-established and proven technology—electric trolleybuses—remains underutilized.

The Trolleybus Advantage

Electric trolleybuses, a form of electric-powered public transportation that has existed for nearly a century, offer distinct advantages over their battery-operated counterparts. Alan Fisher from Armchair Urbanist highlights San Francisco’s existing infrastructure for electric trolleybuses, pointing out that cities like Seattle have also successfully maintained robust networks.

By leveraging existing trolleybus technology, San Francisco could enhance its public transit offerings. Electric trolleybuses provide several benefits:

• Reliable Power Source: Trolleybuses draw power from overhead wires, ensuring consistent operation compared to battery-electric buses, which rely on battery charging schedules.
• Reduced Operational Costs: With lower energy costs and reduced maintenance associated with simpler drivetrains, trolleybuses can enhance the fiscal stability of transit agencies.
• Environmental Benefits: Similar to battery-electric buses, trolleybuses are an eco-friendly option, producing zero emissions during operation.

Expanding San Francisco’s Trolleybus Network

Fisher advocates for strategic investments to expand the network of electric trolleybuses across San Francisco. With its geographical and infrastructural readiness, the city could implement this technology to improve access to transit options for residents in all neighborhoods. Such an expansion could address gaps in the transit network and boost ridership.
