California's Transformation in Train Technology

California's San Francisco is taking a crucial step in the transportation sector as the SFMTA approves a substantial budget to eliminate the outdated use of 5.25-inch floppy disks from its train control systems.

History of Floppy Disks in Muni Metro

Since 1998, the Automatic Train Control System (ATCS) of the Muni Metro has relied on these floppy disks, which have become a notorious bottleneck for modernizing train operations.

  • Three floppy disks are needed to load DOS software for controlling central servers.
  • The system operates trains in automatic mode, allowing operators to supervise.

Modernizing the System

On October 15, the board took a significant step by approving a contract with Hitachi Rail, known for powering advanced train systems globally.

  1. The $212 million deal promises a solution free from floppy disks.
  2. Support services from Hitachi will be provided for 20 to 25 years.

The timeline for this transformation was initially set for 2028, but disruptions caused by COVID-19 have necessitated adjustments to the schedule.
