In a major upgrade effort, San Francisco’s public transit system is investing $212 million to replace outdated floppy disk-based train tracking technology. For decades, the aging system has used these disks to monitor train locations, but this technology will be replaced by modern software in 2027. As one of the world’s most tech-forward cities, San Francisco’s move will bring transit tech into the 21st century.

Floppy Disks: A Relic in a Modern Transit System
Floppy disks, known for their limited 1.44 MB storage capacity, are a relic of the past, largely replaced by more advanced storage solutions like USB drives and cloud technology. Despite being obsolete, the San Francisco transit system has continued using floppies to track subway trains. Each morning, operators have to load the system from these disks, which are part of an outdated software setup vulnerable to frequent disruptions. Recognizing the need for reliability and faster data handling, San Francisco is now moving to phase out this aged technology.
A Costly Shift to Modern Technology
Last week, San Francisco’s transit authorities signed a contract with Hitachi Rail worth $212 million to revamp the aging system. This overhaul is set to replace the floppy disk setup with a fully digital, Wi-Fi and cellular-based system. The new technology will increase the efficiency and accuracy of train location tracking, enhancing operational reliability. Although costly, the investment reflects a commitment to safer, more efficient urban transit.
Transition to Wireless and Cellular Tracking
Hitachi Rail’s system, expected to be operational by 2027, will use wireless and cellular signals instead of the physical disks to pinpoint train locations. This transition not only aligns with modern data standards but also reduces the risk of technical malfunctions linked to older hardware. The system will provide real-time data updates, which should significantly improve the overall transit experience in San Francisco. With fewer technical barriers, the system promises a more resilient network better suited to the demands of a bustling metropolis.
Bringing Public Transit Up to Silicon Valley’s Standards
This modernization of San Francisco’s transit aligns with the high-tech ethos of Silicon Valley, where innovation drives industry and infrastructure. As a city known for its technology leadership, San Francisco’s investment reflects a shift towards aligning its public services with the innovation that characterizes the region. The upgrade promises a more reliable, high-tech solution for millions of commuters. By adopting cutting-edge technology, the city reinforces its role as a leader in smart urban infrastructure.
San Francisco’s transit overhaul demonstrates how modern technology can breathe new life into essential public services, combining innovation with practical solutions.
