A bicycle obstructing the tracks caused delays Tuesday morning for an Amtrak train on its way to Los Angeles, Amtrak officials said.
The bike struck a bystander, but no injuries were reported, an Amtrak spokeswoman said.
Metrolink initially reported that a person had been struck on the tracks.
The train was delayed about 40 minutes.
In a tweet, Metrolink notified riders about 7:35 a.m. that the OC Line 605 train to L.A. was stopped between the Norwalk and Commerce stations. Michael Atchue, a Metrolink spokesman, said the 705 train also was experiencing delays of 10 to 15 minutes.
The Los Angeles County Sheriff’s Department had not received any calls to the tracks, a spokeswoman said.
