BOSTON (WHDH) - Emergency crews worked together to pull a woman from underneath a Green Line train in Boston late Friday night

The incident occurred just before midnight on Commonwealth Avenue near Boston University Central station on the Green Line B Branch.

Boston fire officials say crews responding to the scene called for a technical rescue response, which involved firefighters working with members of the transit police, Boston Police Department, and paramedics to free the woman and transport them to the hospital.

Witnesses said crews used hydraulic lifts to lift the trolley, pulled out railroad ties, and had to cut through the fence separating the tracks to create more room to work.

The injured woman was eventually freed and transported. They are expected to survive.

Shuttle buses briefly replaced service on the branch but it has since resumed.

The incident remains under investigation.
