It started just like any other day at Atlanta's busiest MARTA train station.
Then a rider fell onto the tracks.
Senior MARTA officer Eugenio Pizarro heard a "lot of noise and commotion."
Officer Pizarro rushed downstairs to the platform of the Eastbound lane and found a man on the tracks.
Making the already dangerous situation even more precarious, the MARTA rider on the tracks was pinned under his wheelchair.
"Somehow he lost control of his wheelchair," Officer Pizarro said.

"At the speed, he was able to clear the third rail and land in the middle," the responding officer explained.
