I think that the UP Geneva Sub would be a great add on for tsw2. You have Metra, that operates form Chicago to Elburn, and freight from Kedzie to Clinton. On this route there would be 3 freight yards. UP Global 2, West Chicago yard, and UP Global 3. Global 2 is located in Proviso Illinois, and is a very big yard for UP in the Chicago area, it serves intermodal, manifest. The West Chicago yard is a smaller yard that accompanies autorack and manifest. Global 3 is located in Rochelle Illinois which is about 75 miles west from Chicago, it serves intermodal and manifest. Now for engines and rolling stock, the main UP engines would be the SD70ACe and the AC4400CW. Now onto Metra, which runs from Chicago to Elburn which is 43 miles. Metra rolling stock would be the F40PH-3 and for cars would be the gallery cars kind of like Caltrain. I think this route fits very well with passenger and freight, and would like to see come to Train Sim World 2 someday. Below is the Metra F40PH departing Elburn which is the end of Metra line.
