According to a P.E. contractor on Trainorers.com:

"All that had to be done was to go into the Central Instrument Houses at Shore and Ford interlockings change the control lines to read a maximum of 120 code between Shore and Ford."

"Amtrak already had a system in place that would have prevented the wreck and just was not using it in this way because of philosophical opposition to enforcing severe civil speed restrictions through use of the cab signal system and wayside aspects. Even though they profess to have a "speed signal" system, certain people didn't want to use it to enforce train speed unless their hand was absolutely forced by an FRA mandate."
