The L in Chicago is one of my favorite transit systems to ride in the US.  The system is mostly elevated and at times it feels like you can just reach in to the apartment buildings you pass by because they are that close to the right of way.  But another highlight of the system are the many sharp twists and turns the trains take as they snake their way through the city.  How did some of these, such as the two 90 degree curves on either side of the Red Line’s Sheridan station (pictured here), come to be?  Chicago radio station WBEZ looked in to this question and offers the answer in this article on their website, accompanied by an audio report as well.

Oren’s Reading List is an occasional feature on The Travelogue in which I share articles that I’ve read that might also be of interest to the readers of this website.
