Beginning in the 1960s, several railroads began converting 40' boxcars for bulk loading use by adding loading hatches to the roof similar to a covered hopper. Unloading was more challenging than a covered hopper, but it accommodated shippers who were not set up to receive bottom-outlet cars. And it allowed the boxcar to be used in other services when not needed for bulk loading for better year-round utility on seasonal goods. Typical products included clay and grain and these cars could be found in many areas of the country. Add this unique service to your railroad with these new cars!
