The entire train descended the grade and reached Lac Megantic. The locomotives somehow managed to navigate the turn at the Lac Megantic yard entrance and continued to roll down the line until they finally came to rest. This is the reason the TSB was able to recovery the black boxes. If the engines had been involved in the fire the black boxes would likely have been consumed in the flames.<br /><br />Why the tank cars failed to negotiae the turn the engines managed to navigate is another interesting question. I suspect the answer has to do with the higher mass of the engines resulting in greater track keeping ability plus the free surface effect of the fluids in the tank cars and the higher centre of gravity of the cars themselves.<br /><br />The comments about th difficulty of uncoupling train cars is correct. On tank cars it is made even more difficult due to the installation os special couplers designed specifically to make it more difficult for tank cars to uncouple in a collision or derailment. This partialy serves to explain the way the cars litter the ground like a folded accordian. As they were unable to uncouple they experienced torsional forces which caused them to assume the fanfold arrangement seen in the pictures rather than a linear, off the rails and all lying on one side configuration.<br /><br />Great post!Sushihttps://www.blogger.com/profile/18376999828622609337noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-66463295072748402502013-07-10T01:00:58.417-07:002013-07-10T01:00:58.417-07:00Mr. Sam thanks for your articles re arctic methane...Mr. Sam thanks for your articles re arctic methane clathrates and the possibility of it being abruptly released. But can you and other writers focus on the methane being released thru natural gas production, happening now and getting worse day by day coz of ramped up shale fracking and such. Many of the agencies and industry are trying to downplay and underreport this as long as they can.

They do Not uncouple easily and if you are not a railworker with experience they are difficult if not impossible to be uncoupled. this looks like a set up to me as an old rail worker and I smell sabatage.The oil industry is manifesting its true capacity to destroy civilization for profit. aaronstandingbearhttps://www.blogger.com/profile/14450356069210158694noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-75162479176961512112013-07-09T07:57:15.579-07:002013-07-09T07:57:15.579-07:00Thank you for your excellent analysis!Thank you for your excellent analysis!Anonymoushttps://www.blogger.com/profile/09055675289303898184noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-87905420896588226472013-07-09T06:56:44.627-07:002013-07-09T06:56:44.627-07:00There is an acceleration of Earth toward Runaway f...There is an acceleration of Earth toward Runaway full blown CH4 driven Runaway global warming underway that is on track to destroy Earth life and civilization.<br />And there won't be a morning after in which to watch from afar. Not a chance of rebuilding after the train wreck of global warming coming.. It's Nuts.<br />The use of oil, of fossil full of carbon is flat suicidal and insane.<br />We need to undo past harm and somehow gain real braking control.<br />Control of a string of containers running ever faster downhill. There is Nitrogen cycle to now consider,, there is force of war rising and real feeling of helplessness and disenchantment.<br />There is denial of what's happened but brake on release of Methane from methane hydrate ice has slipped and an inexorable acceleration is on.<br />It'll take Act of God or something to undo this.<br />There is acceleration of force rising and lag time for things to play out but we can be brash and brave and try, try and maybe gain control of future with the luck of things that go to those with willingness to try.. To somehow try and stop the motion of disaster coin coming.. The coin is struck and needs to be taken out out of play.. literally ;by act of god alteration of the metal from which it is made, money.. So the full force of human endeavor can be brought to bear or God help us. If we try at least we tried, tried to raise awareness and speak of a string of dark cars racing downhill gathering speed of force in the dark night.. The dark night of ominous Real unfairness.. Of Enron like profit taking.. Hold.Dale Lananhttps://www.blogger.com/profile/05409842680440987251noreply@blogger.com
