Recently gave this Intermountain GS gondola a bit of attention, and once repairs where finished I decided that it needed a suitable load. In service such cars having drop bottoms often carried various types of aggregate. This car was already heavy as an empty so I didn't want to weigh it down excessively. A Lightbulb moment came in the form of what you see in the photos...not sure what this stuff is but I acquired a bag full of it from it's former life as loose packing material from an industrial supplier. I've had it sitting in my junk storage zone for years...and today it found new life as a perfect nearly weightless aggregate looking type load. Cool bean huh...
