K113 Union Pacific B-50-38/-39 Box Cars

In 1946 and 1947, the Union Pacific added a total of 3,000 box cars that at first glance, appeared to follow the postwar iteration of the AAR box car design. However, the UP’s cars incorporated two significant design differences: their all-welded UP underframes and sides using thinner sheet steel that necessitated the use of interim stiffeners, resulting in an additional row of “alternate” rivets in the center of the panels. As such, these UP cars are both numerous and subtly distinctive, making them perfect subjects for modelers.

The first 1,000 cars (class B-50-38) were delivered in 1946 by Mt. Vernon Car Manufacturing Company. They used the prewar style Youngstown steel doors and Wine ladders, along with two styles of running boards (Apex Tri-Lok and U.S. Gypsum) and four types of hand brakes (Ajax, Universal, Equipco, and Miner.) These cars were delivered in the scheme that featured white stenciling with Armour yellow “ROAD OF The Streamliners” and “SERVES ALL THE WEST.”

The 2,000 members of the B-50-39 class were built in 1947, with 1,500 coming from Pullman-Standard and 500 from from General American. These cars were equipped with improved Youngstown doors and used standard, riveted-type ladders plus two types of running boards (Apex Tri-Lok and U.S. Gypsum) and six types of hand brakes (Ajax, Universal, Equipco, Miner, Superior, and Ureco.) The first 1,500 cars were painted as the B-50-38s were, but the last 500 cars had all Armour yellow stenciling and slogans.

Speedwitch is offering kits to replicate these important prototypes. The kits feature one-piece cast resin bodies and parts, including accurate UP welded underframe, a first, plus injection molded styrene improved Youngstown doors and etched metal Wine ladders, both where appropriate. Three lettering styles are available: white stenciling with yellow slogans, all Armour yellow stenciling and slogans, plus all Armour yellow lettering with the “Be Specific - Ship Union Pacific” slogan. The large 20" UNION PACIFIC introduced in 1956 will be available as a separate small decal. Kits do not include trucks, couplers.
