Hi Folks

Here are the DS/SS/Steel splits, 1945, and 1950, for box and auto
cars in interchange service on the UP, CNW, and GN.


UP – includes LA&SL, OSL, OWR&N, StJG&I markings:

January 1945:
UP_____%____Number
DS_____34.5%____9,538
SS_____0.7%____186
Steel_____64.6%____17,870
Known_____99.8%____27,594
Unknown_____0.2%____69
Total_____100.0%____27,663

July 1950:
UP_____%____Number
DS_____2.0%____478
SS_____0.1%____12
Steel_____97.9%____22,870
Known_____100.0%____23,360
Unknown_____0.0%____2
Total_____100.0%____23,362

In 1945, over a third of the U.P.'s box and auto fleet was double
sheathed – in 1950, it was 98% steel. Overall, it lost about 4,300
cars.


CNW:

January 1945:
CNW_____%____Number
DS_____8.1%____2,031
SS_____73.7%____18,386
Steel_____17.9%____4,475
Known_____99.8%____24,892
Unknown_____0.2%____46
Total_____100.0%____24,938

July 1950:
CNW_____%____Number
DS_____1.0%____238
SS_____51.7%____11,982
Steel_____47.3%____10,967
Known_____100.0%____23,187
Unknown_____0.0%____0
Total_____100.0%____23,187

Nearly three-fourths of the CNW fleet was single sheathed in 1945,
and less than 20% was steel. By 1950, SS was still a majority, but
steel was close behind. Overall there was a 7% loss.


GN:

January 1945:
GN_____%____Number
DS_____83.0%____21,246
SS_____13.8%____3,540
Steel_____0.0%____0
Plywood_____3.2%____826
Known_____100.0%____25,612
Unknown_____0.0%____1
Total_____100.0%____25,613

July 1950:
GN_____%____Number
DS_____64.2%____14,326
SS_____15.6%____3,487
Steel_____11.2%____2,499
Plywood_____8.9%____1,988
Known_____100.0%____22,300
Unknown_____0.0%____0
Total_____100.0%____22,300

The GN had no steel cars in 1945, and was dominated by DS. By 1950
it had reduced its DS fleet by about a third, and added some plywood
sheathed and steel cars. SS was essentially unchanged. Overall, it
lost 3,313 cars.
