do at work,plus visitors on the way:her parents were coming in for Thanksgiving from her hometown.But as she hurried down the subway stairs,she
started to feel uncomfortably warm.By the time she got
to the platform,Lisa felt weak and tired--maybe it hadn’t been a good idea to give blood the night before,she thought.She rested herself against a
post close to the tracks.
Several yards
away,Frank,43,and his girlfriend,Jennifer,found a spot close to where the
front of the train would stop.They were deep in
discussion about a house they were thinking of buying.
But when he
heard the scream,followed
by someone yelling,“Oh,my God,she fell in!”Frank didn’t hesitate.He jumped down to the tracks and
ran some 40 feet toward the body lying on the rails.“No!
Not you!”his girlfriend screamed after him.
She was right
to be alarmed.By the
time Frank reached Lisa,he could feel the tracks
shaking and see the light coming.The train was about 20
seconds from the station.
It was hard to
lift her.She was just
out.But he managed to raise her the four feet to the
platform so that bystanders could hold her by the arms and drag her away from
the edge.That was where Lisa briefly regained
consciousness,felt herself being pulled along the
ground,and saw someone else holding her purse.
Lisa thought
she’d been robbed.A woman held her hand and a man gave his shirt to help stop the
blood pouring from her head.And she tried to talk but
she couldn’t,and that was when
she realized how much pain she was in.
Police and fire
officials soon arrived,and
Frank told the story to an officer.Jennifer said her
boyfriend was calm on their 40-minute train ride downtown---just as he had been
seconds after the rescue,which made her think about her
reaction at the time.“I saw the train coming and I was
thinking he was going to die,”she explained.
