The driver of a Boston subway that narrowly missed a woman who'd fallen onto the tracks said Wednesday she feared something terrible had happened when saw the mayhem on the platform.

Charice Lewis told "Fox & Friends" that she wasn't sure what was going on, but saw people waving frantically at her as she came into the station and braked her train hard, screeching to a halt mere inches short of Sophia Hartdegen.

"I thought the worst," Lewis told "F&F." "I had no idea what was going on."

Lewis, who made the TV morning show rounds Wednesday, said on "The Early Show" that she prayed, "Please God, let this woman be OK" before getting out of the train to check.

Lewis said Hartdegen, who was drunk, just smiled at her.

"I counted all her arms and legs, and I was happy," Lewis told "F&F."

Lewis got a call from fellow Massachusetts Bay Transportation Authority employee Jacqueline Osorio, who was standing on the platform on Friday night when she saw the woman tumble.

Osorio said the scene was "horrific."

Both were recognized by the MBTA for their actions.

Hartdegen said in a statement she was grateful to Lewis and all the people who helped her.
