The consolidation locomotives use saturated steam at a pres-sure of 200 pounds. With 24 x 30 cylinders, and drivingwheels 6;^ inches in diameter, the resulting tractive force is46,600 pounds. The weight available for adhesion is thus utilizedto the best possible advantage. The steam distribution in these locomotives is controlled bybalanced slide valves. The cylinders are arranged with theircenter lines coincident with the steam chest centers. Eachcombination lever is pinned to a long crosshead sliding in twobrackets which are bolted to the top guide bar. This crossheadcarries a lug to which the valve rod is secured. In this waythe motion is transferred from the plane of the link to that ofthe steam chest center, without the use of a rocker. The boil-ers of these engines are straight top, with crown-bar stays, andas far as construction is concern
