In the context of transportation, a hot box typically refers to an overheated or excessively heated axle bearing on a train or a railroad car.

It can refer to a small, partially enclosed space, often made out of glass or other heat-resistant materials, where substances, such as marijuana or tobacco, are heated or burned in order to be inhaled.
