Thanks for the answers! <br />It seems that CWR came into use sometime in the 70's- maybe the 80's? If the improvement in ride and (I assume) maintainability costs were improved as significantly as everyone seems to say they were, how come railroads didn't use CWR much earlier? Was there a change in welding technology or in metallurgy that enabled CWR? <br /> <br />Erik <br />"Still blinded by the science"
