Refreshing to know what you're standing in when you ride an escalator in a station. Enforcement problems? May I suggest cameras, or even DNA. I know it says they use cameras but don't monitor them when the stations are closed, but maybe it's time to change that practice. But the problem is that even if caught, the homeless would consider it a luxury to be in jail.

Keep in mind that a good number of these people are either mentally ill or emotionally disturbed, an indeterminate number discharged from mental hospitals in the "de-institutionalization" wave that swept through some years past. Society does not want to pay for mental hospitals, so society puts these people on the street; this is one result. Having rail passengers pushed off the platform in front of arriving trains is another result. Having psychotic people stab passersby on platforms and in trains is yet another result.
