San Francisco metro still relies on floppy disks since 1998

San Francisco's light rail, an iconic transportation method in the city, surprisingly continues to operate using 3.5-inch floppy disks. This system, implemented in 1998, coincides with a pivotal moment in tech history when floppy disks were being phased out by most companies, including Apple with its iMac G3.

Despite floppy disks being considered obsolete in most contexts, the automatic train control system of San Francisco's metro relies on them for operation. This raises questions about the adaptability of transportation infrastructure to more modern technological innovations.

## Why it matters The persistence of a system based on such outdated technology as floppy disks is a reminder of the gap between technological innovation and the reality of public infrastructure. This can also affect the efficiency and safety of transportation, as older systems may be more prone to failures and operational issues.

## What we know The modernization of the system is expected to take until 2034, meaning that for more than another decade, floppy disks will remain an integral part of light rail operations. This situation reflects a broader challenge in many cities, where the modernization of public services can be slow and costly.

## What’s still unclear Specific plans for transitioning to a more modern system and the technologies that will replace floppy disks have not yet been detailed. The community and public transport users are awaiting more information on how this transition will be addressed and the implications it will have for their daily experience.
