CBTC System to Modernize San Francisco’s Tram Network

The San Francisco Municipal Transportation Agency selected the WSP-PGH Wong consortium to implement CBTC on the Muni Metro tram network to improve its efficiency and capacity. This is reported by the railway transport news portal Railway Supply.

A contract for the SelTrac system was signed with Hitachi Rail in February 2025. The rollout will take place in stages from 2028 to 2034 to avoid disrupting current operations.

The project includes full technical support—from design to commissioning and future maintenance. WSP-PGH Wong will handle system integration, testing, and activation.

Officials in San Francisco expect the new technology to boost the tram system’s capacity by 20%. The upgraded network will span 144 kilometers and 33 stations, covering both underground and surface sections.

Radio-based control will improve safety, ensure more accurate scheduling, and reduce headways—an essential upgrade for busy routes across the city.
