A person was extricated from under a train Saturday evening at Union Station in Boyle Heights.
Rescue crews worked to remove the unidentified person from under the train about 9:50 p.m., and were able to transport the critically-injured patient to a hospital for treatment, Los Angeles Fire Department spokeswoman Margaret Stewart said.
The underground station is located at 2330 E. First St. in Boyle Heights.
Jose Ubaldo, Metro spokesman, said the incident is under investigation, and it was not yet clear if the person fell or jumped onto the tracks before being hit by a northbound Gold Line train coming into Union Station.
One of two train tracks for the Gold Line was temporarily shut down in the area, he said, causing delays up to 20 minutes for passengers traveling between Pico/Aliso and Maravilla stations. Service has since been fully restored.
