<p>[quote user="Paul_D_North_Jr"]</p> <p>While looking for something else, I found this PowerPoint presentation (32 pages/ slides, approx. 1.47 MB electronic file size in ".pdf" format) by the BLET in June 2006 which advocates key-type locks for air brake controls - a "locking air brake valve".  It is sub-captioned as "RSAC V-1" (the FRA's Railroad Safety Advisory Committee is "RSAC"):</p> <p align="LEFT">"<strong>Securing Train Air Brakes</strong>" - <a href="https://rsac.fra.dot.gov/document.php?type=meeting&date=20060518&name=BLETair+brake+RSAC_v1.pdf">https://rsac.fra.dot.gov/document.php?type=meeting&date=20060518&name=BLETair+brake+RSAC_v1.pdf</a> </p> <p align="LEFT">See especially slides/ pages 8 - 10 regarding "Unattended Trains", and then 31-32; draw your own conclusions. </p> <p align="LEFT">- Paul North. </p> <div style="clear:both;">[/quote]</div> <div style="clear:both;"> </div> <div style="clear:both;"> <p><span style="font-family:verdana,geneva;font-size:small;">Well, one obvious conclusion is that the BRT does not dismiss the possibility of tampering or sabotage just because they don’t see any at the moment.</span></p> <p><span style="font-family:verdana,geneva;font-size:small;">I note that while this lock system would prevent releasing the air brakes, it would not prevent air brakes from inadvertently releasing on their own, or losing holding pressure over time. </span></p> <p><span style="font-family:verdana,geneva;font-size:small;">The total solution for securing unintended trains would be a power brake acting on all cars simultaneously from a single control that could be locked with the security of the locking system detailed in the BRT report. </span></p> </div> <p align="LEFT"> </p>
