From the sibling link: > This massive shipment was noteworthy not only for its size, but also because it destroyed one of the Uintah Railway Company's trucks. The truck's brakes failed and it started coasting backwards after breaking a drive chain while struggling uphill, loaded with several thousand bricks. The truck then turned over and caught fire. The driver was not injured, but most of the bricks were lost. I imagine USPS pricing didn't account for that incident!
