MARTA is working to clean up its image and its odor.
Many of its elevators have doubled as restrooms and smell like it. That's about to change with first-of-its-kind technology which catches "offenders" literally—with their pants down.
"The smell hits you so bad. You hold your breath just to hurry up and get off the elevator," said MARTA rider Alicia Porter.
MARTA elevators have a smelly reputation. To get to the train, you often have to ride in a urinal first.
"If you've ever been in a Porta Potty, that's what it smelled like before," said MARTA Director of Elevators/Escalators Tom Beebe.
