Crude petroleum trains appear running through Kirkwood once in awhile on what had been the Eastern Division. Current practice and concern centers very much on safety. Among the precautions are use of empty boxcars, airslide hoppers or other covered hoppers as buffer cars between the train and the locomotives. There are also efforts to re-design the tank cars and new ones with a shield protecting the ends of the cars have shown up frequently in recent trains. All this is in contrast to photos of the crude petroleum trains during WW II. Two images of westbound empty trains in Frisco Power (second edition) show tank car trains with no buffer cars. One shows 1520 near Sullivan (p 171) and the other (p 210) is the Barham photo of 4509 proudly lettered for "Frisco Fast Freight." To be sure, these are most likely empties. Was it general practice in 1942-1945 to pull loaded crude oil trains with no buffer cars? Were there any special rules or procedures written for this traffic? On a side note, it is interesting that the caption on p 210 mentions "and average of seven oil trains of 60 to 70 cars each ... daily." In 2014, when crude oil trains come through Kirkwood, they have 103 or 104 tank cars with a buffer car at each end. There are seldom more than two per day and these frequently have distributed power.
