San Francisco Muni's Rail System Will Spend $212 Million To Upgrade From Floppy Disks

San Francisco's Municipal Transportation Agency approved a $212 million contract with Hitachi Rail to modernize the Muni Metro system's outdated train control system, which currently uses floppy disks and wire loops. Government Technology reports: The software that runs the system is stored on floppy disks that are loaded each morning and an outdated type of communication using wire loops that are easily disrupted. It was expected to last for 20 to 25 years, according to Muni officials. It moves data more slowly than a wireless modem, they said. By late 2027 and into 2028, a new communications-based system, which employs Wi-Fi and cell signals to precisely track the locations of trains, will be installed by Hitachi, which will provide support services for 20 years under the agreement. While the current train control system operates only on the Market Street subway and Central Subway, the new system will control Metro light rail trains on the system's surface lines as well. The Hitachi system is said to be five generations ahead of the current system, said Muni Director of Transit Julie Kirschbaum, who described it as the best train control system on the market.
