The backhead of a steam locomotive is the end of its firebox facing inside the cab. Most of the locomotive’s controls used by the locomotive’s engineer and fireman are mounted on the backhead. All the controls needed to manage the firebox’s fuel intake, boiler’s steam pressure, the locomotive’s speed and direction, and a whole lot more are within easy reach of its crew.
