Below are the series with the largest number of unknowns. If

anyone

can tell me whether they are DS, SS, or steel, I would be most
grateful. A build or rebuild date would also be appreciated.

Larry, CNW/CMO information, such as I have, is interpolated.

Road, AAR, Kind, Series, IL, IH, Door, Capy, Qty 1938, Qty 1942

CMO, XM, Box, 29200-31198, 40'0", 7'11", 5'0", 80000, 611, NA

must be double sheathed. They are listed as steel underframe, rather
than steel frame, and CNW/CMO SS boxcars had a 6' door opening.

(Does

anyone have a photo?) I don't have details on CMO cars, but since
these are listed as having steel underframes, they should date

within

just a few years before the Fowler SS cars began arriving in 1914.
CNW's first SUF boxcars were built 1912-13, and are dimensionally
similar to this CMO series, except IH and cu capy.

CNW, XA, Auto, 34900-36898, 40'6", 10'0", 10'0", 80000, 997, 12

single sheathed, blt.1927, C&NW Chgo. Shops

CNW, XA, Auto, 110000-110998, 40'6", 10'4", 10'0", 80000, 498, 496

single sheathed, blt.1925, AC&F Chicago

btw, all the above are even nos. only.

Thanks, Jack!

I'll list the CMO series as DS, but keep note of the fact that this
identification is interpolated. (I have several other series so
noted.)

Here are the summary tables for the CNW with your data included:

CNW____Jan-38____Apr-42____Jan-45____Apr-49____Jul-50
DS____3,267____1,918____2,031____223____238
SS____19,737____17,922____18,390____12,588____11,982
Steel____520____3,465____4,475____9,738____10,967
Unknown____201____3____42____0____0
Total____23,725____23,308____24,938____22,549____23,187

CNW____Jan-38____Apr-42____Jan-45____Apr-49____Jul-50
DS____13.8%____8.2%____8.1%____1.0%____1.0%
SS____83.2%____76.9%____73.7%____55.8%____51.7%
Steel____2.2%____14.9%____17.9%____43.2%____47.3%
