I just came across a picture in the wonderful book, Next stop Honolulu about the OR&LCo. At page 300 I see very clear a narrow frame tank car. He looks so similar to me, that it could be a former UTLX tank car. But I'm not aware that any of these cars were shipped to Hawaii. I know the cars that went to the WP&YR, but OR&LCo?
Maybe somebody from the list know more.
Meanwhile enjoy the diesel 15 and 19 pages at my web site.
