The line that runs just to the north of Midway Airport is owned by CSX, not 100% sure though. In the area, the transcon parallels I-55 to the north and the Chicago sub is about 3 miles north of the transcon. The Indiana Harbor Belt runs north/south just to the east of Midway and the BNSF Chicago sub and transcon lines connect with the IHB and the IHB connects with CSX just to the east of Midway.
