The San Francisco Municipal Transportation Company (SFMTA) board has agreed to spend $212 million to get its Muni Metro mild rail off floppy disks.
The Muni Metro’s Automated Prepare Management System (ATCS) has required 5¼-inch floppy disks since 1998, when it was put in at San Francisco’s Market Avenue subway station. The system makes use of three floppy disks for loading DOS software program that controls the system’s central servers. Michael Roccaforte, an SFMTA spokesperson, gave additional particulars on how the sunshine rail operates to Ars Technica in April, saying: “When a practice enters the subway, its onboard laptop connects to the practice management system to run the practice in automated mode, the place the trains drive themselves whereas the operators supervise. After they exit the subway, they disconnect from the ATCS and return to guide operation on the road.”
After beginning preliminary planning in 2018, the SFMTA initially anticipated to maneuver to a floppy-disk-free practice management system by 2028. However with Covid-19 stopping work for 18 months, the estimated completion date was delayed.
On October 15, the SFMTA moved nearer to ditching floppies when its board authorised a contract with Hitachi Rail for implementing a brand new practice management system that does not use floppy disks, the San Francisco Chronicle reported. Hitachi Rail tech is alleged to energy practice methods, together with Japan’s bullet practice, in additional than 50 international locations. The $212 million contract contains assist companies from Hitachi for “20 to 25 years,” the Chronicle mentioned.
The brand new management system is meant to be 5 generations forward of what Muni is utilizing now, Muni director Julie Kirschbaum mentioned, per the Chronicle. Additional illustrating the sunshine rail’s dated tech, the present ATCS was designed to final 20 to 25 years, that means its anticipated expiration date was in 2023. The system nonetheless works nice, however the threat of floppy disk information degradation and challenges in sustaining experience in Nineties programming languages have additional inspired the SFMTA to hunt upgrades.
Plenty of Work to Do
Past the floppies, although, the Muni Metro wants many extra upgrades. The SFMTA plans to spend $700 million (together with the $212 million Hitachi contract) to overtake the sunshine rail’s management system. This contains changing the loop cable system for sending information throughout the servers and trains. The cables are mentioned to be a extra urgent concern than the usage of floppy disks. The getting old cables are fragile, with “much less bandwidth than an previous AOL dialup modem,” Roccaforte beforehand advised Ars. The SFMTA is reportedly planning for Hitachi to begin changing the loop cables with a brand new communication system that makes use of Wi-Fi and mobile alerts for monitoring trains by 2028. Nonetheless, the SFMTA’s board of supervisors nonetheless must approve this, the Chronicle mentioned.
Along with previous storage codecs and the communication infrastructure, the Muni’s present ATCS contains onboard computer systems tied to propulsion and brake methods, in addition to native and central servers, and extra. The SFMTA’s web site says that the present estimated completion date for the whole overhaul is “2033/2034.” In accordance with the supplied timeline, it appears just like the subway know-how substitute section is anticipated to happen in “2027/2028,” after which there’s an on-street know-how set up section.
Like with different entities, the SFMTA’s sluggish transfer off floppy disks may be attributed to complacency, funds restrictions, and problems in overhauling essential know-how methods. Numerous different organizations have additionally been sluggish to ditch the dated storage format, together with in Japan, which solely stopped utilizing floppy disks in governmental methods in June, and the German navy, which continues to be making an attempt to determine a substitute for 8-inch floppies.
