Continued heating creates steam bubbles in the front tubes, which are naturally separated from the hot water in the steam drum, and are taken off. However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs.

The "South Park" is a fireless locomotive which differs from a steam locomotive. It has no way of producing its own steam. The boiler was filled two-thirds to capacity and then steam was piped in from the central power plant boiler. As the steam in the boiler diminished, the water in the fireless boiler turned into steam.
