Liked: CA: S.F. ready to replace Muni train control system that runs on floppy disks

San Francisco transportation officials want to replace the "antiquated" infrastructure that uses floppy disks to run the Muni Metro light-rail system and awarded the first contract Tuesday for the roughly decadelong project.

The $700 million project to replace Muni Metro's train control system with a modern one would be its first upgrade in almost three decades. The city installed the current train control system in 1998, which requires loading three-and-a-half inch floppy disks each morning to operate the light-rail network.
