   Current FRA rules require civil speed enforcement only on track segments   
   that carry trains at speed higher than 125mph.   
      
   Absent civil speed enforcement system, there is the possibility of using   
   signal speed to enforce the following speed limits: 20, 30, 45, 60, 80,   
   100, 125 and 150. Apparently signal speed control was not used to   
   enforce speed of either 45 or 60mph on this curve which would have   
   reduced the damage considerably or eliminated it completely. This would   
   involve indicating an Approach Medium aspect (45) or a Cab Speed 60(60)   
   at the signal at Shore interlocking for trains traveling east. Such   
   signal speed enforcement is used for example on the Elizabeth S curve,   
   where all trains get Approach Medium on signals appraching the curve in   
   both directions.   
      
   Starting 2016 civil speed control is supposed to be enforced on all main   
   line tracks irrespective of the maximum speed allowed for trains on said   
   track, so even this segment would have such speed control enforced by   
   the ACSES (Advanced Civil Speed Enforcement System).
