<p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-size: small;"><span style="font-family: verdana,geneva;"><span style="font-size: small;">I am curious about locomotive collision posts.<span style="mso-spacerun: yes;"> </span>As I understand it, they are intended to protect the crew in cases of collisions with highway vehicles as well as locomotives and rolling stock.<span style="mso-spacerun: yes;"> </span></span></span></span></p> <p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-size: small;"><span style="font-family: verdana,geneva;"><span style="font-size: small;"> <o:p></o:p></span></span></span></p> <p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-family: verdana,geneva;"><span style="font-size: small;">I have seen how the EMD F-units were designed to buckle between the cab and the rest of the locomotive body, in order to absorb impact while keeping the cab relatively intact.<span style="mso-spacerun: yes;"> </span>Of course, this tended to work only at very slow speeds.<span style="mso-spacerun: yes;"> </span>I have seen geeps with their cabs demolished when cars or a caboose rode up the unit in a collision.<span style="mso-spacerun: yes;"> </span>But as far as I know, this was all prior to the advent of “collision posts.”</span></span></p> <p class="MsoNormal" style="margin: 0in 0in 0pt;"><span style="font-size: small;"><span style="font-family: verdana,geneva;"><span style="font-size: small;"> <o:p></o:p></span></span></span></p> <p><span style="font-size: 12pt; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;"><span style="font-family: verdana,geneva;"><span style="font-size: small;">So what is it that collision posts are expected to do?<span style="mso-spacerun: yes;"> </span>It certainly does not look like they had any benefit in this BNSF collision, and that was only a 22 mph impact.<span style="mso-spacerun: yes;"> </span></span></span></span></p>
