Actually the B&W trailer is dual gage! It has rail for both 2 foot and standard gage (for hauling our speeders). The hopper is our scratch built ballast hopper with air doors to dump both inside and outside the gage. Interesting that we had the inside of the hopper coated with Rhino brand spray on pick up bed liner. The car was returining from the Rhino installation in the photo. The exterior was painted shortly after.
