Specific Item Information: From series WITX 5861-5884, built June 1977. Early-1990s era repaints without logos or FRA-224 stripes. 22 roof hatches.

Model Information: ScaleTrains first announced this model in 2017 and first delivered it in March of 2018. It is a highly detailed model of a specialized 3-bay cover hopper car. It features: a 1970s carbody featuring 10 column-style posts per side and unique double hip roofline, Separate granuflator plumbing, Per prototype: 22 or 28 roof hatches, Photo-etched stainless steel running boards and end platforms, Separately-applied ladders, Finely-detailed underbody brake detail, Body mounted semi-scale plastic Type E knuckle couplers, All-new ASF Gould-cast 70-ton Ride Control Trucks with finely rendered raised foundry data, 33” machined metal wheels, Coupler cut levers, Trainline hoses, Intricate brake plumbing, Color matched to Tru-Color Paint colors whenever possible, Printing and lettering legible even under magnification.

The knuckle couplers at first appear to be McHenry's due to the outside spring, but in fact seem to be a new design. We tested them by coupling them to a Micro-Train model with body-mount couplers and they played nicely together. They seem to be somewhat delicate, as one of the two sample models that arrived had a broken coupler. The detail is excellent, but one of the half-ladders literally fell off as I rotated the car in my hands. I am very leery of actually running these things.

Prototype History:
Found throughout North America, these unique freight cars are commonly found in large groups near major carbon black producers or users. They can also be seen singularly or in small blocks of cars in mixed freight trains. Both prototypes were painstakingly researched from field documentation, photographs, reference books, and builder drawings.

During the 1970s, Thrall Manufacturing Co. introduced a new railcar designed for handling carbon black. These 3-bay, 70-ton capacity covered hopper cars boasted a volume of 5750 cubic feet, and measured 51’ over their ends. Unlike traditional covered hopper designs, where the end slope sheets are plainly visible, these cars featured an enclosed, boxy design, which was a necessity due to a special design feature to aid in the unloading of carbon black.

At the inside ends of the car are special inflatable bags, called “granuflators”. When the car is loaded, they lay flat inside the car. When inflated with pressurized air, the granuflators expand, and push the carbon black towards the outlets. As typical with cars designed to haul carbon black, they featured tight-sealing 16” round roof hatches (22 or 28 depending upon customer specifications), sampling spigots on the car sides, and “butterfly” type outlet gates.

The “1970s” version of the 5750 represents production from approximately 1977 until 1979. This car features ten column-style posts per side and a unique roofline. While the ends are peaked and the end roof panels feature a single slope, the remaining roof panels feature a dual slope and a steep shoulder where it meets the side plate. Many of these cars are still in service today.

Road Name History: In 1989, Witco built a 50 percent capacity expansion of its Ponca City, Okla., carbon black production facility. The 75 million pound production unit will increase the plant's capacity to 235 million pounds. This project, along with incrementally capacity increase, or debottlenecking projects completed or currently in progress at other plant locations, will increase Witco's total carbon black capacity to more than 435 million pounds a year. The new unit will be based on technology developed by Witco's Concarb division.

Continental Carbons was at least at one time operated as the ConCarb subsidiary of the Witco Corporation. Witco was merged through a succession of transactions into Chemtura. It is through its association with Witco that the WITX reporting marks became associated with Continental Carbons. The Continental Carbon Company was acquired by the China Synthetic Rubber Corp. in 1995.

Brand/Importer Information:, Inc. is an upstart HO and N Scale model manufacturer that was founded by a team with more than 125 years of accumulated experience in the model railroad hobby and industry.

ScaleTrains is specifically focused on the tiny details in the printing and quality of the construction. The four friends who founded the company are all avid modelers themselves. Their factory is located in Tennessee. Unlike most other companies, they offer a range of different levels of complexity in their offerings so as to be able to provide products for both the budget-conscious collector as well as the detail-focused model enthusiast without compromising on quality for either.

They range covers the following, by increasing level of detailing:
  1. Operator™ trains are built for modelers who enjoy running high-quality, realistic trains at an affordable price. Designed from builder’s drawings and photographs, Operator models have fewer factory-applied parts and simplified printing. For added versatility, super-detail parts are available separately.
  2. The Rivet Counter™ line strives to create the most accurately detailed models imaginable. The real-world counterpart is meticulously researched to ensure prototype fidelity. Each model features numerous factory applied parts including roadname and road number specific details whenever possible.
  3. Museum Quality™ models are historically accurate replicas of the most famous locomotives in North American railroading history. Exhaustive research and a commitment to perfection combine to create the ultimate scale model. Museum Quality trains establish new standards which make them just as legendary as the original.
