I appreciate all that have replied so far, both current and former railroad employees and rail fans. The reason I brought this subject up is I like watching all kind of subject material on YouTube. I recently watched a few videos about when bears encounter people. Sometimes those encounters were deadly. Since I am a rail fan, I got to thinking about what happens when a conductor has to walk the train due to a malfunction in bear country. I would be scared of a bear encounter. According to the following video, looks like CP has had lots of bear vs trains. According to your replies, looks like bears are not the only thning I would need to be concerned about.
