Some riders got knocked down, and one boy briefly got his foot caught in the machinery.

“As we were going up, the escalator just…we were probably about three quarters of the way up, and the escalator just stopped, jerked forward, and then sped backwards and collapsed down,” said Jennifer Nottage, who was injured on the escalator.

“I was scared thinking that I wasn’t going to be able to pull my feet up, but then when I did, I knew that I was out, so I just had to run up,” said Elijah Nottage, Jennifer’s son.

Jennifer Nottage added that she wanted to thank the anonymous passerby who lifted her young daughter over the railing to keep her from getting hurt.

The MBTA released a statement regarding the incident:
