Posted by Bill West on Fri Feb 6 17:33:19 2015, in response to How Railroad Could Have Avoided / Ameliorated Fiery Crash, posted by SLRT on Thu Feb 5 09:14:04 2015. Okay, let's get some reality back in here.-MNR/LIRR, Uh where does one think that LIRR rail goes after it slopes down? Certainly not to the ground. The fact is there is plenty of opportunity to catch under it too. Thus there is no useable difference in car impact resistance between the two systems because both can be snagged. -Neither is the rail mounting an issue, it's fragile insulators and it's going to be ripped up and tossed in any incident. The lag screws under the MNR C supports can be pulled straight up by a car as readily as they can be pushed over, it will depend more on the tearing object than the mount. -A barrier around the end of the third rail not only has to clear the shoe it has to clear the coach overhang. This is very tight, there is barely space for the protection board let alone a barrier of a useful strength. You wouldn't want a barrier to wedge the car either, it would increase the risk of derailing the train. -What is the relevance of all the detector/watchman ideas? The engineer did "detect" the problem and reacted as quickly as the train could respond. Now if someone has a method of predicting from a minute and a mile back that a car will enter the tracks AND not get off by the time the train gets there and it can be done for thousands of crossings at a taxpayer affordable price then maybe there's something worth posting about. -Any one location can be singled out after an accident but unless one can predict the future we'd need to fix thousands of crossings to meaningfully reduce the risk. Arguing for financially unattainable overpasses is not recognizing the scale of the problem. -Politically this crossing may get closed but it will not be because it is a meaningful cure to the ongoing problem. -The third rail puncture and fire consequence was a once in a century fluke, I've never heard of such an extreme case before. It is just unfortunate and not anything that has high enough probability to warrant trying to change the long shot future odds of a repeat. Bill |
