The San Francisco Municipal Transportation Company, which runs town's Muni Metro gentle rail, claims to be the primary US company to undertake the floppy disk. However in the present day, the SFMTA is raring to desert its reliance on 5¼-inch floppy disks—simply give it about six extra years and some hundred million {dollars}.
SFMTA members spoke not too long ago ABC7 Bay Space Information and detailed the company's use of three 5¼-inch floppy disks every morning. Floppy has been a part of Muni Metro's Automated Prepare Management System (ATCS) since its set up within the Market Road subway cease in 1998. ATCS consists of a number of elements, “together with computer systems onboard trains that management propulsion and brake programs, central and native servers, and communications infrastructure, corresponding to loop cable sign wires,” SFMTA spokesman Michael Roccaforte informed Ars Technica.
The floppy disks are for loading the software program that runs the central server, Roqueforte stated:
Rocafort stated preliminary planning for the overhaul of ATCS, together with the elimination of the floppy disks, started in 2018 and was anticipated to take a decade from preliminary planning to completion. As a result of an 18-month-long COVID-19-related hiatus, completion is predicted from 2029 to 2030. The SFMTA hopes to decide on a contractor by early 2025 and can then launch an in depth challenge timeline.
“In the end, our aim is to create a single prepare management system for your entire rail system,” stated Jeffrey Tumlin, SFMTA transportation director. abc7,

“If it ain't broke don't repair it,” some individuals say. However whereas the floppy-disk-dependent prepare management system is at the moment working, there are challenges in counting on the older know-how, which the SFMTA has highlighted over time.
The transport physique says the prepare management system was solely constructed to final 20 to 25 years, that means it exceeded its anticipated lifespan in 2023. In 2020, the Muni Reliability Working Group, composed of native and nationwide transit consultants, really helpful changing the transit management system inside 5 to seven years.
When requested how “harmful” it was to improve floppy disks, Tumlin defined abc7 That it's all about danger.
“The system is at the moment working completely high-quality, however we all know that with every rising 12 months, the danger of information degradation on the floppy disk will increase and sooner or later a catastrophic failure will happen,” Tumlin defined. abc7,
Beforehand, the transportation company had claimed that ATCS had grow to be more durable and dearer to take care of over time. It additionally discusses the challenges to find staff who know find out how to use the dated system.
“We’ve got to retain programmers who concentrate on programming languages from the '90s to run our present programs, so we’ve got a technical debt that spans a number of a long time,” Tumlin informed San Francisco's KQED in February 2023. Has occurred.”
