Metra says service on its Milwaukee West Line may not be back to normal until Friday, at the earliest, because of a fiery freight train derailment near Elgin.
All trains have been blocked on the line since at least 12 cars of a Canadian National train derailed at about 5:30 a.m. today in an industrial area at 31 West 504 Spaulding near Elgin and Bartlett. Three of the cars caught fire, but there were no injuries and no evacuations.
Officials said the train was carrying three chemicals — sodium hydroxide, ferrous sulfate and organic acid — but they were not on the cars that caught fire. Bartlett police said two of the burning cars carried fiberboard and scrap metal and the third was empty.

A camera phone photo from Tim Olk shows fire continuing to burn in at least one car.
