I rode the MAX when living there for a few years. I vividly recall screaming drugged out homeless riders being a regular feature. The last time I rode, a year ago, there was someone in the throes of the fent-bends in my section, who smelled like he was dying (he well may have been).

These incidents haven't made me fear, because I am a relatively big and tall male, but they _definitely_ will for others. And even then, they aren't pleasant.

You simply don't run into those things often on trains/subways in Europe (I lived in Spain for a year and traveled extensively in Europe during that time, and on other europe trips prior). So fix those issues, and then I am sure people will want to ride the rails.
