FUD is strong here
The implication that $200 odd million is going to be used to replace JUST the floppies is a bit strong, as is the emphasis on Hitachi Rail being Japanaese.
Hitachi Rail took over Ansaldo STS Signalling operations in 2015, who had taken over Union Switch and Signal in 1988.

So this contract is for the American based part of Hitachi ex USS at Pittsburgh, to deliver a new train control system.
Signalling systems at the trackside generally have a lifespan of around 40 years, with control systems a typical lifespan of 20 years.
Which makes any update a "Generational" one, and with the system and safety assurance certification requirements also mean the technology and OS are usually an "IT" generation behind before being put into operational service.
So this update is timely, maybe a little late on those measures but not out of place for the value and time of service expected from a new signalling system.
