Travelers passing through Los Angeles Union Station Thursday were ankles-deep in water as a section of the historic station flooded amid heavy rains.

The flooding in the pedestrian passageway began about 6 a.m., a Los Angeles Metro spokesman told KTLA.

Metro and Amtrak provided passenger carts to carry passengers and luggage through the flooded area, while Metro, Metrolink and Amtrak officials worked together to mitigate the situation, the spokesperson said. Some passengers walked through ankle-deep water.

Video from around 9:40 a.m. showed water flooding the area, where train riders pass through to get to their platforms. Staff members could be seen working to clear the water from the passageway.

By 1 p.m., L.A. Metro said the water had been cleared.

No delays were reported as a result of the flooding at the station.

Authorities did not provide details on what caused the flooding, but it happened as heavy rainfall drenched the Southland.

Downtown L.A. has received more than 3 1/2 inches of rain since Wednesday, according to the National Weather Service.
