You know that what you eat affects your sleep, but did you know that the reverse is also true? Studies now show that people who are sleep deprived tend to eat more fat-rich foods, simple carbohydrates, and fewer vegetables, possibly because sleep loss alters chemical signals connected to metabolism and hunger.
Figure 6. Figure 6 is a bar graph showing the number of main-track train derailments and the number of main-track train collisions per year from 2001 to 2010. In 2001 there were 7 main-track train collisions and 132 main-track train derailments.
The CN train involved in the derailment outside Brighton, for example, was built as a conventional train would be, with three locomotives in the front hauling 137 rail cars behind. But it was stretched out 8,850 feet and weighed nearly 12,000 tons.
