Re: Depression era / pre-WWII Covered Hoppers?
In the NPRHA's The Mainstreeter, Vol 8 No. 4, Fall 1989, I with Matt Herson covered the "Acquisition of Covered Hoppers" by the NP, using primary sources from the NPR corporate records at the Minnesota Historical Society. This covers only two-bay covered hoppers.toggle quoted messageShow quoted text
By May 1940, NP had leased 30 1958 CuFt covered hoppers from General American Car Co., stated in correspondence to be copies of ACF Plan 6147192-B 70 ton cars.
Arsenic, from smelters in Tacoma and Butte, was a commodity for which they anticipated the cars to be used in addition to cement. Covered hoppers owned by URT were already in service between Billings and Chicago handling sugar for Mars, Inc, and much later NP acquired Airslide cars for that type of service. Early operations of those cars are described.
For those who may be interested, deliberations started in 1934 with the Western Association of Railway Executives (WARE), with member roads CB&Q, C&NW, CGW, MSP&P (MILW), Rock Island, GN, M&StL, MStP&SStM, NP, and UP. Details are provided on the varied thinking and interactions.
