> However, budget challenges put the project's timeline into question. The SFMTA's train upgrade project isn't just a migration off of floppy disks but also a "complete overhaul of the current train control system and all its components, including the onboard computers, central and local servers, and communications infrastructure," Roccaforte said.

> Much more critical than the dated use of floppy disks is the system's loop cable, which transmits data between the central servers and the trains and, according to Roccaforte, "has less bandwidth than an old AOL dial-up modem."

Also, they're already late as hell, what's 5 more years? 5 1/4 isn't going to become more obsolete than it is at this point.

You don't need more "bandwidth than an old AOL dial-up modem" for train control. What Roccaforte left out is that the MTA spent over a decade trying to keep the trains from slicing up the inductive loop. No idea how the new trains are working out, but I'm pretty sure they never found a permanent fix for the old ones.
