From the Tacoma Public Library. Caption:
A Northern Pacific Railway refrigerator car is stationary on tracks in a 1957 photograph requested by the Pacific Car & Foundry Co. All vital information regarding the boxcar is listed on its side, including weight, dimensions and capacity limits. Apparently this was a newly engaged car as of September, 1957.
Use the slider above the photo to enlarge it.
The photo shows that the car owner is Pacific Car & Foundry and NP is the lessee. A Northern Pacific document, Status Of Authorities For Expenditure (http://www.nprha.org/NP%20AFE%20Index/NP_1960.pdf), shows that this car was approved for purchase by the railroad on 1-8-60 and this action was completed 12-30-59 (an after-the-fact authorization probably for tax purposes).
As this car appears to be a one-of-a-kind, what happened to it? I would think its relatively short, forty-foot nominal length contributed to an early demise, but that is just a guess.
