The frontend main rod brasses are not adjustablebut are provided with solid round husb- and particular attention was given to thecab arrangement to locate all necessarypiping and fittings for the greatest con-venience of the engineer and fireman. Theboiler pressure is 200 lb. The fireboxis 1144 in. long by 84J4 in. wide, whichgives a grate area of sq. ft. Thereare 216, 2% in. tubes and 40, Syi in. flues,.

Instead of six-feed lubricators withfeeds to the cylinders, these locomotivesuse four-feed lubricators, the cylinderfeeds being omitted in accordance withthe standard practice on the Nickel Platewhich has been found to be entirely satis-factory. The boiler is of the conical-connectiontype with combustion chamber and isequipped with type A top header super-heater. Security brick arch and butterflytype firedoor. A Duplex stoker is used 19 ft. long. The heating surface of thefirebox, combustion chamber and archtubes is 280 sq. ft., the evaporative heat-ing surface of the tubes and flues 3,497sq. ft. and the superheating surface 882sq. ft. Special features include a cast steel ashpan, Woodard outside connected throttlewith lever support designed to providefor expansion of the boiler, Na
