What's up with those triangular pee deterrents at CTA stations

Yes, but: The CTA doesn't plan to add any more to stations, an agency spokesperson tells Axios.

Catch up fast: These urine deterrents were installed in 2012 as part of a small pilot program, the spokesperson says.

• They're located at select Orange, Red and Brown Line stations, including Halsted, Addison, Harold Washington and Howard (where "urine was an issue").

How it works: Sand under the contraptions helps absorb the urine, and the protrusion from the wall helps prevent pee from building up in corners. CTA says these are common on European transit.

Zoom in: The city has faced backlash in the past for a lack of public restrooms, according to a 2021 Tribune investigation.

Of note: CTA did not respond to Axios' question about whether other anti-urination tactics are planned for buses and trains.
