A while back I read an interesting article about the CTA yellow line, aka the Skokie Swift. You should definitely read the article because it has some great pictures to go with it. The narrative was so interesting I started having dreams about riding the Skokie Swift. So I finally found myself with plenty of time on my hands and took a trip to see Skokie.
It is a rather weird configuration. What is to stop people from walking around the back of the platform and hopping up and not paying?
So there it is. I wish I had something to add but I don't. It was exactly like the article described.
