Okay, anyone who thinks a “Hotbox” has anything remotely to do with smoking…is dead wrong. Its not smoking in your car, its not smoking in your restroom…heck, it has [nothing to do] with smoking anything, at all. The term has been around since the 1880s, and here is what it truly means: A hot box is the term used when an axle bearing overheats inside a railroad car’s Journal Box. The Journal is a cast to the truck frame box in which the axle bearings were housed in. It used oil-soaked rags or cotton packing to reduce the friction of the axle against the truck frame. When the oil leaked or dried out, the bearings [overheated] often [starting a fire] or melting and locking up the wheel, causing a derailment or burning the train car if not detected early enough. That…is a HOTBOX
