Posted by Bill West on Sun Dec 1 16:55:59 2013, in response to Re: PHOTOS: MNR Derailment, posted by Dutchrailnut on Sun Dec 1 15:36:14 2013. Just as brake failure in your car can be things other than a loss of brake fluid, there are more causes for railway brake failure than loss of air. Besides loss of brake pipe air connects the air in the car reservoirs to the cylinders bringing you to a stop. An engineer would have to be blacked out to not sense one of the several signs that he was running out of air (inability to release normal braking, the horn and bell don't work, in some designs the electrical contactors stop working interrupting traction power, air gauge about 2 feet from his face, etc).A conductor friend detected an impending air loss from 2 cars back when he heard the anti slide braking feature cycling. Engineer was already securing the train by the time friend got to the cab to say something is going wrong. Bill |
