HOT BOX RESEARCH--A STUDY OF REFRIGERATOR CAR JOURNAL BOX PACKING
The data presented in this report show that drippings from the bunker drains are entering the journal boxes of refrigerator cars. The amount of this moisture and brine is sufficient to change the incidence of hot boxes to a pattern which differs from that existing in other types of cars in that the end boxes nearest the drains run hot more frequently. The drain design is under study with the object of improving this condition. Two methods of sampling were employed. The first method consisted of a laboratory analysis of 50 samples of the entire packing content from two adjacent journal boxes removed from 25 refrigerator cars. The second method consisted of the extraction of oil samples from the bottom of two adjacent journal boxes of 25 refrigerator cars.
