         6 . The guardrail system of  claim 1 , wherein the second and third guardrail posts are steel yielding posts. 
     
     
         7 . The guardrail system of  claim 1 , wherein the end guardrail post is a steel yielding post. 
     
     
         8 . A guardrail end terminal system comprising:
 a first guardrail post at a first end of the system;   a second guardrail post located subsequent to the first guardrail post;   a third guardrail post located subsequent to the second guardrail post;   an anchor attached to the first guardrail post;   a first cable hanging bracket on the second guardrail post;   a second cable hanging bracket on the third guardrail post;   a brake tube at a second end of the system opposite to the first end of the system;   a braking slug at an end of the brake tube; and   a first cable connected to the anchor and extending through the first cable hanging bracket and the second cable hanging bracket to be connected to the braking slug.   
     
     
         9 . The guardrail system of  claim 8 , further comprising:
 a guardrail extruder head mounted on the first guardrail post.   
     
     
         10 . The guardrail system of  claim 9 , further comprising:
 a fourth guardrail post at the second end of the system opposite to the first end of the system;   a fifth located prior to the fourth guardrail post;   a guardrail mounted to the second, third, fourth and fifth guardrail posts; and   wherein the guardrail is positioned in the guardrail extruder head.   
     
     
         11 . The guardrail system of  claim 8 , further comprising:
 a second cable attached to the anchor and detachably connected to the guardrail between the first and second guardrail posts.   
     
     
         12 . The guardrail system of  claim 8 , wherein the first guardrail post is a weakened wood post. 
     
     
         13 . The guardrail system of  claim 12 , further comprising:
 a bearing plate at the first guardrail post through which the anchor extends; and   a support extending from the second guardrail post to the bearing plate to provide support to the bearing plate from the second post.   
     
     
         14 . The guardrail system of  claim 8 , wherein the second and third guardrail posts are steel yielding posts. 
     
     
         15 . The guardrail system of  claim 10 , wherein the fourth and fifth guardrail posts are steel yielding posts. 
     
     
         16 . A guardrail end terminal system comprising:
 a first guardrail post at a first end of the system;   a second guardrail post located subsequent to the first guardrail post;   a third guardrail post located subsequent to the second guardrail post;   a fourth guardrail post at a second end of the system opposite to the first end of the system;   a fifth located prior to the fourth guardrail post;   an anchor attached to the first guardrail post;   a first cable hanging bracket on the second guardrail post;   a second cable hanging bracket on the third guardrail post;   a brake bracket on the fourth and fifth guardrail posts;   a brake tube attached to the brake bracket;   a braking slug at an end of the brake tube; and   a first cable connected to the anchor and extending through the first cable hanging bracket and the second cable hanging bracket to be connected to the braking slug.
