You'd never be able to tell based on this board, but the Windy City is like the country's railroad capital - Tons of yards and busy junctions in and around the city, and 6 of the Class I railroads (UP, CP, CN, BNSF, CSX, NS) meet here, plus Amtrak, Metra (Diesel and Electric), The "L" and the country's last real interurban line (the CSS&SB).
