All train service at the station was stopped as dogs inspected the packages. The packages were “rendered safe” and the station was reopened around 9:50 a.m., authorities said.

Metrolink spokesman Scott Johnson says the owner of the track, BNSF Railway, issued the shutdown order when the package or packages were discovered. Johnson says the freight operator did not share details like location or description.
