"Required" might not be the right word, but here's an article about how the San Fransico Trains are updated via floppies - https://www.wired.com/story/san-francisco-muni-trains-floppy-disks/

In the US at least it's not about required, but more legacy support. There are still a lot of old systems that work, but use old technology.
