Howdy, Mike. I'm probably the farthest thing from even being proficient in older freight car areas. However, I've tried to educate myself and I do not recall seeing any. Wish Vince Griesemier were on here-maybe he's lurking. I suspect he or Brad Slone might be able to give a more definitive answer.
I will tell you what I know, which is not much there are probably others that could shed more light than I. The Frisco had a series of double door single sheathed boxcars in the 1511000 to 151400 series that had a reinforced C channel side sill. Also around 1946 they had the 154000 to 154300 series that where of an all steel construction with a heavy side sill. There where probably other cars from smaller series that had heavy side sills but these are all that I know of. Brad
Brad, thanks for the details and information. Now I just need to find a picture of any of this series; I'm come up zeros so far, but will keep searching. Best Regards,
I have diagrams for the 15100-151099, 151100-151199, 151200-151284, & 151285-151499 series cars. I will post them soon. The mother-board on my PC fried, and I have been limping along with my spousal unit's laptop. I am returning to the Apple, and have been shopping around for a new computer, scanner with a large table, and printer.
