AT&SF Bx-3 and Bx-6 boxcars
COL. CHET MCCOID: SAN DIEGO, CA; AUG. 1956: COLLECTION OF BOB’S PHOTO
ATSF 32075 (above) is an ex-member of the FE-P class, but now is a single door car, validated by the stencil, “SINGLE DOOR” on the left door. It has been re-roofed with a radial type roof and was in the Bx- 56 class when photographed in 1956. This member of the FE-P
class (below) still had the ampersand in its reporting marks when photographed in 1947, although the car number is not discernible and the Santa Fe emblem is barely recognizable. It does display the mix of plate and corrugated steel doors common on these cars.

FE-R. The first 500 cars were almost exactly like the forty-footers but sim- ply stretched. They had the same num- ber of vertical U-section members, and the ends, roof, underframe, and trucks were of the same type, albeit longer where necessary. The second 500 cars reflected improvements of the mid- 1920’s. They used radial steel roofs and cast sideframe steel trucks with inte- gral journal boxes.

Many of the cars were modified over the course of their service lives for oth- er uses. Of the 5,000 original boxcars of the Bx-3 and Bx-6 classes, 4,170 were converted to stock cars between 1942 and 1953 and assigned to classes SK-2, - 3, and -5 (see “Essential Freight Cars,” installment 18 in the December, 2004, issue of RMC.) In 1951 and 1952, refrigerator car doors and insulation were added to 45 cars that were placed
in salt service.
In 1951 and 1952, two groups of 200 cars each from the Bx-6 class were con- verted and assigned to zinc concen- trate service between Mexico and Oklahoma. The conversion involved the removal of the outside sheathing boards and addition of angle irons to reinforce the bottom three sheathing boards. These cars were assigned to two series: 40250-40449 and 40800-
