PROTOTYPE AND BACKGROUND INFO:

As more trains exceeded Plate C dimensions with taller and taller cars, the caboose cupola became ineffective for watching over a train. By borrowing another railroads caboose, Union Pacific found that bay-windows provided better train visibility, were safer, and more comfortable to ride in than a cupola. They placed an order for 100 cabooses with International Car Company for a new class of caboose being delivered in 1979. Large protected end porches, 70-ton National Swing Motion trucks, elevated toolboxes, oil-fired heat, and hydraulic coupler cushioning were some of the new features that made these crew favorites.

A single CA-12 prototype was created with comfort and safety improvements. However the order was cancelled as UP inherited recently-built Rock Island cabooses (CA-13). UP modified the CA-11 fleet with many of these features creating a sub-class of the CA-11. Additional unique modifications were made to these iconic cabooses as they were no longer needed for regular train service, several of which Athearn has created detailed versions.
