   You would be wrong, because at both locations where the   
   above wrecks occurred, there ALREADY WERE cab signals   
   suppliemented with speed control, and those systems have   
   been in place for years.   
      
   Cab signals and speed control (until the Metro-North   
   accident) applied ONLY to signal indications (i.e., would   
   apply brakes if engineman did not take appropriate action   
   after passing a more restrictive signal indication).   
      
   After the Spyten Duyvil wreck, Metro-North installed cab   
   signal "drops" approaching certain speed restrictions. These   
   operate independently of signal indications.   
      
   The Amtrak Frankford Junction wreck was also a "slowdown"   
   NOT associated with signal indication, and again, the   
   existing cab signal/speed control system did not enforce it.   
      
   ACSES -- which DOES enforce ALL timetable speeds and   
   slowdowns, WOULD HAVE prevented it, but ACSES wasn't in   
   service yet at that particular location.
