Chicago's first railway opened in 1848. They are called Galena and Chicago Union Railroad as well as the Illinois and Michigan canal. 
 You're welcome. 
 Great. Any other info regarding history or infrastructure? 
 That sounds like a crazy idea! Thanks so much for your help today! 
 Chicago P.D. is my favorite! Had no idea it was in Chicago. Just kidding! Haha. What can you tell me about Chicago's infrastructure?
