Sorry R2 & Joe but these arguments have their limitations. Who exactly in Amtrak should be faulted for not knowing two weeks ago that such a change would be needed specifically at Shore/Frankford? Is there a crystal ball to tell us which of the hundreds of speed drop locations on both the freight and passenger roads will be critical in this matter in the next 10 years? Then how about all the other ways that accidents occur that hindsight will tell us that a minor change to an existing system would have prevented?Hindsight finger pointing is not a constructive safety engineering method. It's looking over all the potential risks at all the potential locations and somehow coming up with a policy that will hit exactly at the risks that subsequently actually occur that would represent genius. Because covering all of the mere potentialities is not realistically feasible and would actually raise the system complexity to the point of causing new risks. Bill |
