In another post and reply interchanges between other roads and Frisco has been mentioned. In Crystal City MO, there is/was an interchange between MoPac/Frisco/PPG. PPG was the glass plant there which had its own yard and tracks. MoPac used the PPG tracks to get to the Frisco tracks to get down to St. Gen. (If you ever go to St. Gen it looks kinda funny because when you go to the north part of town where the Frisco tracks come in, there is a small/medium sized UP(MoPac) yard there off the Frisco main) PPG would recieve Frisco hoppers loaded with Silica sand from a mine at Ludwig north of Festus. So the discussion is can anyone add anymore info to this little hub of activity? I know I'm leaving a lot out and I'm thinking of trying to get a little article together covering this area because there was a lot going on and it would be a great place to model.
