   There's actually an electrical wire spcification   
   called "locomotive grade". I saw some of that cabling   
   in place at, of all things, a computer "server farm"   
   about 15 years ago.   
      
   For whatever reason they had replaced it the next   
   time I was there and had my camera with me.
