Inbound and outbound service on Metra's BNSF line was halted Saturday afternoon after an Amtrak train struck a pedestrian near Westmont, officials said.
Service had resumed with extensive delays at around 5:45 p.m., according to Metra.
The BNSF line, which originates at Union Station, services the western suburbs of Chicago, including Naperville and Aurora. t
Amtrak tweeted that one of its trains was stopped west of Chicago due to a "trespasser incident."
