It's been awhile since I spotted this industry, but there's a mattress manufacturer a few miles away from the yard near a steel beam and specialty shapes manufacturer. We would spot the steel plant daily or every two days (usually coils, sheet and plate steel loads) but the mattress manufacturer would only get a car about every two to three weeks. It was a loaded 20k gallon tank car placarded 3082, if I remember correctly, which is hazmat but doesn't really require special handling. Anyway, rather than unload the car after we spotted it, they would unload it as they used the product, so the tank car functioned as their storage. You could fit two or three tank cars on the spur at a time. And that's exactly what we would do sometimes considering how infrequently we'd spot that industry. As far as the other components of the end product and the finished mattresses themselves are concerned, trucks handled that side of the business. Only the liquid polyurethane resin that made up the foam was shipped by rail.
