DS/SS split 1945 ATSF help needed

Hi Folks

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

January 1945:
ATSF_____%____Number
DS_____17.1%____6,022
SS_____21.7%____7,649
Steel_____45.9%____16,209
Other_____14.4%____5,089
Known_____99.1%____34,969
Unknown_____0.9%____308
Total_____100.0%____35,277

July 1950:
ATSF_____%____Number
DS_____1.2%____432
SS_____21.7%____7,549
Steel_____69.0%____24,024
Other_____7.9%____2,754
Known_____99.8%____34,759
Unknown_____0.2%____68
Total_____100.0%____34,827

These tables exclude DS cars in the series 40000-40024, class Bx-25,
which the ORER describes as "Brick", on the assumption that they are
not in interchange service.

The ATSF retired over 90% of its double sheathed cars, and an even
100 of its single sheathed. It nearly halved its "panel" fleet, but
increased its steel cars by almost 50%. Overall, it had a minor
decline.

There are over 300 cars in 1945 whose sheathing is
currently "Unknown", with most of them in the following series:

Road, AAR, Kind, Series, IL, IH, Door, Capy, Qty 1945, Qty 1950
ATSF, XAP, Auto, 6330-6347, 50'6", 12'4", 14'6", 66000, 15, NA
ATSF, XAP, Auto, 6350-6378, 40'6", 12'4", 12'6", 80000, 26, NA
ATSF, XAP, Auto, 6450-6460, 50'6", 12'4", 14'6", 71000, 12, NA
ATSF, XAP, Auto, 6550-6569, 50'6", 10'10", 14'6", 76000, 20, NA
ATSF, XAP, Auto, 8101-8160, 50'6", 10'5", 14'6", 80000, 55, 2
ATSF, XA, Auto, 8161-8259, 50'6", 10'5", 14'6", 80000, 98, 11
ATSF, XA, Auto, 9422-9887, 40'6", 10'0", 10'1", 80000, 26, 9
ATSF, XA, Auto, 62846-62946, 40'6", 10'0", 12'6", 80000, 11, NA
ATSF, XM, Box, 261551-262571, 40'6", 10'0", 6'0", 80000, 17, 4

I think the following series is DS, based on a Charles Winters photo
of 62723 posted on the NEB&W site. However, Folio 211 on the Santa
Fe Railway Historical and Modeling Society web site lists part of
this series (62000-62049) as class Fe-25, which is steel sheathed
(and 50' !?!):

ATSF, XA, Auto, 61510-62750, 40'6", 10'0", 10'1", 80000, 63, 24

If anyone could inform me about the sheathing type
(DS/SS/Steel/rebuild/panel) and build or rebuild date for above
series, I would greatly appreciate it.

Best wishes,

Class Fe-13, rebuilt as steel sheathed cars in 1937, modified during WW
II with extended roofs for aircraft and auto parts service.

ATSF, XAP, Auto, 6350-6378, 40'6", 12'4", 12'6", 80000, 26, NA
Class Fe-15, rebuilt as steel sheathed cars in 1937, modified during WW
II with extended roofs for aircraft and auto parts service.

ATSF, XAP, Auto, 6450-6460, 50'6", 12'4", 14'6", 71000, 12, NA
ATSF, XAP, Auto, 6550-6569, 50'6", 10'10", 14'6", 76000, 20, NA
Both Class Fe-13, see above.

ATSF, XAP, Auto, 8101-8160, 50'6", 10'5", 14'6", 80000, 55, 2
Class Fe-9, rebuilt as steel sheathed cars in 1936.

ATSF, XA, Auto, 8161-8259, 50'6", 10'5", 14'6", 80000, 98, 11
Class Fe-11, rebuilt as steel sheathed cars in 1936.

ATSF, XA, Auto, 9422-9887, 40'6", 10'0", 10'1", 80000, 26, 9
Class Fe-L, built by AC&F in 1909 as double wood sheathed automobile
box cars and never rebuilt; the few remaining cars in this class were
retired soon after WW II ended.

ATSF, XA, Auto, 62846-62946, 40'6", 10'0", 12'6", 80000, 11, NA
Also class Fe-L, see above, but equipped with 12'6" double doors.

ATSF, XM, Box, 261551-262571, 40'6", 10'0", 6'0", 80000, 17, 4
Class Bx-19 and Bx-20, converted to box cars from wood-sheathed auto
cars of class Fe-N and Fe-O and renumbered by adding "2" to the
original numbers.

I think the following series is DS, based on a Charles Winters photo
of 62723 posted on the NEB&W site. However, Folio 211 on the Santa
Fe Railway Historical and Modeling Society web site lists part of
this series (62000-62049) as class Fe-25, which is steel sheathed
(and 50' !?!):

ATSF, XA, Auto, 61510-62750, 40'6", 10'0", 10'1", 80000, 63, 24
Surviving cars of Classes Fe-N and Fe-O, these were wood sheathed auto
cars built by AC&F in 1914 to essentially the same design as Class
Fe-L. All of these cars had massive steel underframes with four
fishbelly sills; most were rebuilt during the 1930s into steel sheathed
cars of classes Fe-5, Fe-12, Fe-15, and Fe-19. The few that weren't
rebuilt were rapidly retired after WW II, freeing up the number series
for the postwar renumbering of some Class Fe-25 50' steel double door
auto cars; these had been rebuilt as steel sheathed cars in 1942 using
the underframes and ends of Fe-Q class sectional wood sheathed auto
cars originally built in 1924.

Hi Folks

Here are the revised DS/SS/Steel splits, 1945, and 1950, for box and
auto cars in interchange service on the ATSF, with data provided by
Richard Hendrickson added in. Thank you, Richard, for providing this
information in such a thorough fashion.

January 1945:
ATSF_____%____Number
DS_____17.2%____6,076
SS_____21.7%____7,649
Steel_____46.6%____16,435
Panel_____14.4%____5,089
Known_____99.9%____35,249
Unknown_____0.1%____28
Total_____100.0%____35,277

July 1950:
ATSF_____%____Number
DS_____1.3%____445
SS_____21.7%____7,549
Steel_____69.0%____24,037
Panel_____7.9%____2,754
Known_____99.9%____34,785
Unknown_____0.1%____42
Total_____100.0%____34,827

These tables exclude DS cars in the series 40000-40024, class Bx-25,
which the ORER describes as "Brick", on the assumption that they are
not in interchange service.

The ATSF retired over 90% of its double sheathed cars, and an even
100 of its single sheathed. It nearly halved its "panel" fleet, but
increased its steel cars by almost 50%. Overall, it had a minor
decline.

The DS/SS split went from 44% DS, 56% SS in 1945 to 6% DS, 94% SS in
1950.
