But that's another story.
K&K: You are so correct. Here's the conclusions of the "study" at sciencedirect that was linked:
Results: Our regression analysis shows that the introduction of blue lights resulted in a 84% decrease in the number of suicides (CI: 14–97%). Limitation
The analysis relies on data from a single railroad company and it does not examine the underlying suicide-mitigation mechanism of blue lights.
Conclusion:As blue lights are easier and less expensive to install than platform screen doors, they can be a cost-effective method for suicide prevention.
