The X26 series were 40' World War I composite box cars based on an AAR design.

Due to a variety of door and ladder combinations within subclasses, photographs should be referenced for accurate road numbers. Photos of models cannot be trusted for legitimate road numbers, but photos of completed models are included for illustration purposes.

The X26C

Following World War II, the Pennsy turned to converting several classes of out-of-date boxcars to new steel equipment of modern dimensions. The 3500 X26C's were the product of one such rebuilding program. It converted the USRA single sheathed boxcar to a 1944 AAR design boxcsr while retaining the original 5/5/5 Murphey ends and USRA underframe.

Three versions of thre X26C's rolled out of the Pennsy shop in Terra Haute, Ind., since the program spanned the years 1945-49. Of the existing 9763 X26's, 3500 were selected. The first and largest block of approximately 2500 new cars had early 7' Youngstown doors and a straight paneled Murpy roof. The next 500 cars employed the Superior door applied to the same car body. The final 500 cars differed in use of a diagonal panel roof, then becoming widespread, and a modern lightweight 7' Youngstown door.

To accommodate the increased height of the modern car while retaining the original Murphy corrugated ends, a spacer was needed. This modification came in the form of a 24" additional steel plate above the 5/5/5 corrugations. The ends were also widened with new square corner posts.

An AB brake system was also applied. Power hand brakes were added, too. Photo evidence shows Ajax, Klasing, Superior and Universal power hand brakes were used.

THE X26C's were placed in th series 104260-107759.

HO scale models have been produced by Funaro & Camerlengo (resin kit) and Sunshine. The F&C kits are offered with a variety of door options. Mount Vernon Shops offers decals for this class.
