Conservationist: The risk to train passengers from collisions between trains using the train station and deer from the wildlife refuge is insignificant. In the 12 years since the refuge was established, only 15 trains have been damaged in collisions with deer, and no passenger has been injured as a result of such a collision. The wildlife refuge, ttherefore, poses no safety risk. Conductor: You neglect to mention that 13 of those 15 collisions occurred within the past year and a half, and that the number of deer in the refuge is rapidly increasing. As the number of collisions between deer and trains increases
does the likelihood that at least one such collision will result in passenger injuries.
