According to Metra, they've changed their minds about canceling rush hour service tonight. All trains are now running between Chicago and Aurora on the BNSF Metra line.
"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.
Metra is warning riders to still expect service delays through the evening. Normal service is expected to resume tomorrow.

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."
