"Arrowhead's Committee Design Hopper is surely among the finest models ever created."

David Lotz, Editor of the CB&Q and D&RGW historical society publications Burlington Bulletin and The Prospector, and former Product Director of Railway Classics brass models.

 

 

About the prototype:

The "committee design" car refers to a family of cars whose design specifications were set forth by Norfolk & Western, Chesapeake & Ohio and Pennsylvania Railroads. It is one of the most prolific hoppers ever constructed, and it has a rich history. Depending on how one tells its story, the committee design hopper will mean different things to different people. It is one of the largest, single classes of freight car (of any type) to ever be constructed, and simultaneously, it represents a failure for cooperating railroads to standardize around a single design.

As the craft of car building developed, improved axle ratings set into play conditions for the development of new 70-ton cars. Where the Norfolk & Western railroad had long embraced practices of standardization on its own railroad, the president of the N&W, R. H. Smith, thought to reap the advantages of this concept through the cooperation of other railroads as well. The idea was that, if cooperating railroads could standardize the design of a single car, economies of scale would result in material efficiencies for all of the parties.

Smith found agreement with the Pennsylvania and Chesapeake & Ohio railroads. These three railroads were among the largest carriers of coal. Collectively, they rostered 31% of the nation's hopper cars--an impressive statistic when one considers that the attrition of the 1960s and 1970s hadn't yet ravaged the industry with mergers and bankruptcies. Although the design of the car was a committee effort, the Chesapeake & Ohio directly managed the task through its Mechanical Design Office in Richmond, Virginia. By December 1957, there was consensus on the design of a 70-ton, 13-post car with 39'-10" interior length, 10'-6.75" exterior width dimensions and a combination of 45 and 30 degree slope sheets.

 In 1958, the railroads agreed to build one prototype each. C&O built car #300006 at its Raceland Car Shops and assigned it to the H33 car class. N&W built car #59000 at is Roanoke car shops and assigned it to the H12 car class. And, Pennsylvania built car #274001 at its Hollidaysburg car shops and assigned it to the H39 car class. Immediately following the construction of its prototype, the C&O sent #300006 to the National Malleable and Steel Castings Company in Cleveland, Ohio for testing. N&W #59000 was left unpainted for a period of strain testing.

While the PRR embraced the design, the Norfolk & Western railroad resisted constructing additional cars. They took the position that the design was larger than the loading capacity necessitated and the dimensions should be reduced. According to Andrew Dow, the Norfolk & Western had experience with cars of spare cubic capacity as being "both dangerous and expensive to operate" (Mainline Modeler, September 1990, pg. 67). To underscore this perspective, N&W's H10-class hopper were smaller, lighter and less expensive than the committee design car, and yet despite this, they were rated to carry the same load. The N&W did not see the committee design car as a step forward, and therefore, not the right platform to rally its standardization efforts around. Other than the prototype, the N&W would never build another committee design car. That said, the N&W did employ the lessons of the committee project to design its H11 hopper--a car with many design similarities as the committee car. And, not unlike the PRR's H39 class, the H11 class is among the largest single car class ever constructed. (We know this well; head's up Norfolk & Western modelers!)

 

Pennsylvania Railroad:

Only the Pennsylvania Railroad moved the design forward for immediate production. Eventually, the PRR alone would construct 16,133 committee design cars. This car comprised its massive H39 fleet--one of the largest car classes of any type. In fact, the H39 was so numerous, that by the time these cars made it onto Conrail's roster, Conrail temporarily abandoned its attempts to standardize around 100-ton cars. The Pennsylvania's H39 car is a fact of Eastern railroading from the 1960s through the 1990s, and beyond that, many cars continued in secondary roles and company service.

 

Denver & Rio Grande Western:

Where the Denver & Rio Grande Western once preferred drop bottom gondolas for moving coal, by 1957, this preference shifted from gondolas to open hoppers. In the period between 1957 and 1966, the D&RGW began purchasing 70-ton open hoppers in earnest. Of the three different designs acquired during this period, the committee design hopper was the most prominent 70-ton hopper. And arguably, this car set into play the general character of Rio Grande's fleet of open hoppers from 1960 and onward.

In 1960, the Rio Grande purchased a lot of 200 committee design hoppers. These were built by Bethlehem Steel Company and numbered 17500-17699. Although these weren't the first 70-ton open hopper the Rio Grande acquired, they were the first to have design elements characteristic of a modern conveyance. Previous orders were fulfilled by Bethlehem Steel Company (albeit, an NYC design) and American Car & Foundary, and these cars had (mostly) welded side posts. Welded joints have a greater tendency to break at the weld seam of the side sheet and post, and it is a construction method that was soon viewed as less favorable than riveted methods.

From the 1960 delivery and forward, the Rio Grande never looked back--both in terms of the committee design and its builder, Bethlehem Steel Company. From here forward, every new, HT AAR class car that the Rio Grande purchased was from Bethlehem, and every new, 70-ton HT class car that the Rio Grande acquired was of the committee design. In 1962, the D&RGW placed a second order of committee design cars. These cars were numbered in 17700-17899 series. They had ASF roller bearing trucks, Miner hand brakes, and Wine double door locks, hopper doors and hopper frames. In 1966, they placed a final order of 400 cars. These were placed in the 14600-14999 series. Unlike the previous lot, the 14600-14999 cars had 1955 Ajax hand brakes. In total, the D&RGW owned 800 committee design hoppers. This car comprised 44% of its total 70-ton hopper fleet.

 

Southern Railway:

In June 1966, the original Norfolk Southern (NS) purchased 70 committee design hoppers from Bethlehem Car Co. In 1974, the Southern Railway acquired the Norfolk Southern's committee design cars when the Southern acquired the NS. These cars were repainted into Southern's sharp Claytor lettering scheme and rolled into its massive fleet of steel, three-bay hoppers. In 1982, the Southern Railway merged with the Norfolk & Western, and the 57 cars that remained on the roster were of the owner "Norfolk Southern" once again.
