Hi Folks

Here are the breakdowns of double sheathed, single sheathed, and
steel box, auto and ventilator cars, April 1949 and July 1950, for
the N&W, NKP, and GTW railroads, from ORERs and other sources.


N&W:

April 1949
N&W_____%____Number
DS_____2.2%____201
SS_____10.6%____970
Steel_____86.9%____7,922
Other_____0.0%____0
Known_____99.8%____9,093
Unknown_____0.2%____22
Total_____100.0%____9,115

July 1950
N&W_____%____Number
DS_____1.1%____101
SS_____10.5%____943
Steel_____88.3%____7,900
Other_____0.0%____0
Known_____100.0%____8,944
Unknown_____0.0%____0
Total_____100.0%____8,944

The N&W cut its small DS fleet (all ventilator cars) in half from
April 1949 to July 1950. It also trimmed its SS and steel sheathed
cars, for a slight overall decline.

The 22 Unknowns in 1949 are in the series 60500-60999; their
dimensions are close to those of the ventilated DS cars, including a
36' 0" interior length. They are most likely DS, in which case the
N&W would have retired all of its "regular" DS cars between April
1949 and July 1950.


NKP:

April 1949
NKP_____%____Number
DS_____0.7%____59
SS_____2.4%____199
Steel_____96.8%____8,178
Aluminum_____0.1%____10
Known_____100.0%____8,446
Unknown_____0.0%____3
Total_____100.0%____8,449

July 1950
NKP_____%____Number
DS_____0.0%____0
SS_____2.3%____198
Steel_____97.6%____8,410
Aluminum_____0.1%____10
Known_____100.0%____8,618
Unknown_____0.0%____0
Total_____100.0%____8,618

The NKP retired the last of its venerable double sheathed cars from
1949 to 1950. A smattering of SS remained, as did its 10 aluminum
cars – everything else was steel. (Thanks to Richard Hendrickson, Al
Brown, and Jeff Coleman for identifying most of the 1949 Unknowns.)


GTW:

April 1949
GTW_____%____Number
DS_____3.2%____263
SS_____50.9%____4,227
Steel_____45.9%____3,809
Other_____0.0%____0
Known_____99.9%____8,299
Unknown_____0.1%____6
Total_____100.0%____8,305

July 1950
GTW_____%____Number
DS_____2.4%____202
SS_____41.5%____3,544
Steel_____56.1%____4,789
Other_____0.0%____0
Known_____100.0%____8,535
Unknown_____0.0%____0
Total_____100.0%____8,535

The GTW went from having the majority of its cars SS in 1949 to a
steel majority in 1950. Overall it grew slightly.
