Entering the later stages of World War II, a number of America's over-burdened railroads commenced the construction of outside braced, wood sheathed, box cars commonly referred to as "War Emergency" cars.  The Northern Pacific's War Emergency Box Cars were especially distinctive as the only car of this designation to be built with six-panel sides.

Although built in 1944, photo documentation shows these cars in everyday revenue service extending from the time of their construction into the 1970's.  Except for paint applied to ends, underbodies, and truck side frames, all other painting, lettering, and the monad herald remained unchanged through the revenue life of these cars.

As you have come to expect from Challenger, this now underway production has been carefully researched, carefully documented, and will result in models of exceptional quality.
