San Diego Transit Awarded $60 Million for Trolley, Electric Buses

Why It Matters

The funding accelerates San Diego’s transition to cleaner, faster public transportation, directly supporting California’s climate objectives and enhancing regional mobility.

Key Takeaways

• $48.3M funds Orange Line trolley enhancements.
• $12.1M supports first 30 electric buses charging infrastructure.
• Project targets 81M annual trolley rides.
• Funding aligns with California’s zero‑emission transit objectives.
• Improves regional mobility and reduces greenhouse gas emissions.

Pulse Analysis

The California Transit and Intercity Rail Capital Program has earmarked more than $60 million for the San Diego Metropolitan Transit System, marking one of the largest single‑year infusions for a West Coast agency. The grant arrives as the San Diego Trolley logged a record 81 million boardings in fiscal year 2025, underscoring both demand and the pressure to modernize aging infrastructure. State officials view the funding as a catalyst for meeting the 2030 zero‑emission target set by the California Air Resources Board, while also bolstering regional economic competitiveness.

The $48.3 million portion of the award is dedicated to the Orange Line Improvement Project, which will replace track, upgrade signaling and introduce higher‑capacity vehicles on one of the system’s busiest corridors. Planners expect a 15 percent reduction in travel time and a measurable boost in on‑time performance, benefits that translate directly into higher rider satisfaction and increased fare revenue. By integrating modern control systems, the project also lays groundwork for future automation, positioning San Diego’s light rail as a benchmark for other legacy networks seeking efficiency gains.

The remaining $12.1 million will fund phase 1 of electrifying MTS’s Kearny Mesa Division, installing an overhead charging network to support an initial fleet of 30 battery‑electric buses. This rollout is expected to cut diesel‑related emissions by roughly 5,000 metric tons annually and lower operating costs through reduced fuel consumption and maintenance. Moreover, the visible presence of silent, zero‑emission buses serves as a public‑policy showcase, encouraging neighboring jurisdictions to pursue similar investments. As federal and state incentives converge, San Diego’s hybrid approach—modernizing rail while scaling electric bus service—offers a replicable model for midsize American metros.
