One thing that hasn't been mentioned in this discussion is that in 1953/54 UTLX lost all their 6500 gal type V tankcars that they were disinclined to upgrade to AB brakes. It seems to me that these small ca[pacity cars were most useful in the bulk oil distributor market, where small dealers were inclined to order small quantities. I wonder if it was apparent at this time that the small dealer business was shrinking, making Union Tank Line less than interested in buying new small capacity cars.
