Axle Box Body

An axle box, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings.

A hot box is the term used when an axle bearing overheats on a piece of railway rolling stock.

The journal bearing was replaceable, but if neglected, it would heat to a temperature where the babbitt bearing alloy would melt away, leaving the brass carrier riding on the steel axle, and result in a "taper journal".
