It's hard to imagine railroad workers watching this short film without thinking that their company is trying to blame them for all the industrial accidents that occur. It correctly argues that workers should always keep safety in mind while working, but implies that the company would willingly allow people to take time off for simple dizziness or not penalize workers for falling behind in their work. It also insists that the company "does everything in its power to prevent accidents", which in my corporate experience is exactly as likely as *individuals* doing everything possible; that is to say, not at all likely. And by casting this as a kind of sermon by a company-town minister, Union Pacific turns human error into a sin against the company and one's loved ones. Safety, of course, should be regularly emphasized in dangerous industrial environments, but this message appears to be rather one-sided and heavy-handed.
The MST3K version of this short, shown in its "Amazing Transparent Man" episode and available on its "Shorts Volume 2" DVD, is filled with well-timed jokes and entertaining silliness. It's quite funny, unless you've encountered some of the tragic accidents that occur in the short, which would make it hard to be amused by the banter. But it's possible to laugh at the goofy MST3K lines while remembering the short's message: that safety must be consciously and continuously practiced in hazardous environments.
