The BNSF line is running after a halted service for about four-and-a-half hours Wednesday afternoon.
"Service has resumed, however, we anticipate that there will be some delays throughout the remainder of the evening. ... We are encouraging passengers to come to (Chicago Union Station) as service has resumed and trains are running. Please note that service will not run at a normal schedule," Metra said in an alert on its website.
The boom of the crane was removed from the tracks at around 4:15 p.m. Trains began rolling past at about 4:42 p.m., while the base of the crane, a truck that had been on its side all afternoon, was still tipped over just to the north of the tracks.
Metra has put an advisory message up on its website saying that no rush-hour trains will run Wednesday evening, into our out of Union Station in Chicago, due to the fallen crane in Westmont that has blocked all tracks since 11:51 a.m. Wednesday morning.
"At this time, we cannot estimate when normal service will resume. We do not expect BNSF trains to operate during rush hour," the advisory reads. "We are recommending passengers consider alternate travel options. Some passengers may be able to take the Union Pacific West line and others should consider alternate forms of transportation."
