I just came across your reply Paul B. Appreciate the extra data as always! I found it very interesting to hear the cars also carried anhydrous ammonia. Over the years I saw many tankers marked for anhydrous ammonia sevice at the old Solvay Process site. I don't know if they were coming or going loaded but do wonder if any Suburban cars got a "backhaul" from Solvay if ammonia was being loaded from there. Glad to also hear of the late 60's time frame. That fits right into my layouts time frame of late 60's to mid 70's! Todd K.
