The figures got me thinking....nine round trips in three months is a cycle time of ten days, give or take - I can't decide if the text is saying nine round trips per car or combined total for both cars . . .
As most freight cars averaged less than nine trips PER YEAR, these not only have to be the trips for both cars, but are still remarkable. PFE was proud that its cars averaged between ten and eleven round trips per year, higher than any other reefer owner and higher than most railroads' freight cars of any type. For these two cars to have made so many trips suggest that they were (a) short trips, and (b) probably hastened along for test purposes.
