   It might.  However, for detecting those it would be best to inspect the   
   track before the oil train passes over it.  Some of these lines have a   
   lot of oil traffic over them, but if the line is in such poor condition   
   as George describes, it seems to me it is likely a secondary line of   
   some sort.  The secondary line near here that receives the most oil   
   traffic only gets two of those 100 car trains per week or so.  I would   
   think this line might be something like that.   
      
   If a car with the ability to do certain base track inspections were put   
   to use there, I would rather see it on the daily lumber mill train.   
   That's more likely to find incipient defects than the twice per week oil   
   train.
