Something different before more tank cars. Covered hoppers were a small, but growing, class of cars.
Cement
In this era, the most common commodity for covered hoppers was cement. Once again, New Britain doesn't have a local bulk cement company that would receive such cars. Building Supply companies would have received bagged cement in box cars. It wasn't unusual for cement to be delivered in covered hoppers for large projects, though. So it would be feasible to have some delivered to the bulk tracks.
The LNE was a major shipper of cement. Some sources I've identified include Lehigh Portland Cement Co in Sandt's Eddy, and Fogelsville, PA. Atlas Cement Co. in Northampton, PA served by N&B and connecting to the LNE in Bath. The DL&W also interchanged at Bath, but the primary connection for eastbound traffic was the LNE. Alpha Cement Co. in Martins Creek, PA was also served by the LNE.
Intermountain produced an LNE car, and I'll pick one up if I see one although it needs different door hardware. I have an F&C resin kit to build for a different prototype.
Sand
The large industries of New Britain received other commodities that were often shipped in covered hoppers, though. Sand being the most common one.
The city may have received sand for roads in the winter. I'm modeling early November, so this is a good option. However, cinders were also often used, and would have been readily available from the power houses of the many industries. It's unclear what New Britain was using at the time.
Whibco was one of the largest producers of sand. They were based in New Jersey, but had facilities in Marion, MA and Provincetown in Cape Cod, both on the New Haven. Boston Sand & Gravel in Scituate, MA is another possibility, also on the NH.
Outside of New Haven territory, Whibco had locations in NJ (served by the PRSL, a Pennsylvania/Reading joint operation), and Slingerland and Selkirk, NY which were served by the D&H.
However, another use for this type of sand was sandblasting. Russell & Erwin had such facilities, and Stanley Works probably did too.
Russell & Erwin was moving away from casting in 1950, but Stanley Works also needed casting sand. Sand for industrial casting, such as for cast iron, needed to be more uniform and was a higher grade. New England sand typically wasn't suitable. The Pennsylvania Glass Co. in Mapleton or McVeytown, PA was a common supplier, both served by the Pennsy. Mifflin Sand Co, also located in McVeytown, was acquired by Pennsylvania Glass in 1952.
The PRR H32 is a Bowser model.
Aluminum Oxide
Items were also blasted with Aluminum Oxide (also called "Alumina") instead of sand. The Aluminum Ore Co was located in Bauxite, AL and owned the Bauxite & Northern Railroad that interchanged with the MP.
Soda Ash
The other most common commodity that is likely to have come to New Britain is Soda Ash. This was used as a cleaner/degreaser for steel and other metals prior to pickling in an acid bath. As a base, it was also used to counter acids prior to being released into the local environment or runoff. As a likely source, I've chosen the Solvay Process Division of Allied Chemical and Dye in Syracuse, served by NYC and DL&W. Diamond Alkali in Painesville, OH was served by FP&E (PRR) and NYC, with connections to the B&O and NKP. Another possibility is Pittsburgh Plate Glass Co. in Barberton, via PRR, B&O or Erie.
Spring Mills Depot released this B&O wagon top covered hopper. They are hard to find, but F&C still produces a resin kit.
Road Salt
Road salt was also starting to be used in larger quantities. Until anti-caking agents were developed in 1956, it couldn't be stockpiled. So it would be delivered on an as-needed basis. I don't have any evidence that New Britain had started to use it during my era, but this was a time where its use across New England was increasing exponentially.
The Restof mine of International Salt Co. in York, NY was the major source for this commodity. It was the largest salt producing mine in the US, and second largest in the world. Located on the Genessee & Wyoming it had connections to several railroads. But the Erie to Maybrook is the most likely routing to New Britain. DL&W or NYC are other possibilities.
The Erie model is also an Intermountain ACF 1958 cu. ft. car, with the "closed" side design.
