Li’s claim alleges negligence by the Muni operator and by the San Francisco Municipal Transportation Agency.

“I turn around and I saw this frail woman getting dragged along with this train, she’s like running trying to keep up with it a little bit,” witness Will Hayworth told KPIX 5 last month. “But the train’s not slowing down, it’s just like moving along, and she’s just getting dragged along, and I’m like ‘oh my God.’”
