@arstechnica "The floppies have been part of Muni Metro's Automatic Train Control System (ATCS) since its installation in the Market Street subway stop in 1998" - Uh, was using 5 1/4 inch floppies not already embarrassingly outdated by 1998?
Not that it's always best to use the latest thing, but floppy disks aren't really known for being a very reliable solution.
Is it that hard to at least transition to a DOS system with more reliable and fast storage?
