Description

The large cylindrical object is not a boiler but a "steam drum" which was a third full of boiling water. It was filled with steam from a stationary plant then the loco would use the steam as it moved around. As the pressure dropped in the drum the water would boil more fiercely (As the temperature at which water boils drops with lower pressure). These locos were extremely successful and were largely used in gasworks oil refineries and other places where naked flames could not be tolerated.
