I think that at the point of derailment, the event recorder will show instantaneously skewed data such as speed going from 45 MPH to 0 or brake pipe air going to zero at the same instant due to the train coming apart. It will be the data in the minutes and seconds preceding the incident that will likely be the most telling.If the train was moving at or close to MAS and braking was normal then one has to look to mechanical failure or track failure BUT in this case, the engineer has already stated that the train failed to brake properly when a brake was called for. The event recorder should be able to tell how fast the train was going, whether the wheels were turning or locked and when and how much brake was called for. Then the investigators will have a solid basis for their investigation. |
