Action News spoke to the mother, Teneka Greer, who was holding her 14-month-old baby daughter Akayla. Akayla was in the stroller at the time it fell off the platform at the station on 56th Street.
Both mother and daughter are fine.
"Today, everybody's doing a little better. We're a little shook up from what happened yesterday," Teneka Greer of West Philadelphia said.
Teneka says it happened in a split second.
She was standing on the platform next to the stroller and turned around to look at the clock.
When she turned back, the stroller was gone.
She didn't see it plunge off the platform and onto the tracks.
"I was looking at the time and it just happened suddenly. I would never ever imagine. I literally just turned my head to look at the time. I started looking around and then I heard a scream and that's when I started to scream," Teneka said.
Teneka jumped down onto the tracks to grab Akayla.
A woman standing nearby punched the alarm button, while two men jumped onto the tracks to help.
SEPTA stopped the next train that would have been there within minutes.
Teneka and the others got Akayla back onto the platform and she was rushed to the hospital.
Remarkably, Akayla suffered minor bumps and bruises and doesn't appear any worse for the wear today.
"She's doing a lot better, a lot better than it actually looks. I'm extremely happy and very much blessed," Teneka said.
Teneka was a nervous wreck and is only now calm enough to talk about it.
She shudders to think of what could have happened.
And she's grateful for the support she's getting from well wishers.
"I do appreciate everybody that's praying for us and that did pray for us. She's doing better and we're blessed. I'm ecstatic that she didn't break any limbs or anything like that," Teneka said.
The platform at the station is open to the weather and the floors are tilted toward the tracks to allow rain water to drain off.
Teneka says wasn't aware of that yesterday and she hopes SEPTA will post a warning.
