. Railway mechanical engineer . orked single expansion at any time. When drifting,saturated steam can be admitted to the high-pressure cylinderstlirough a pipe connected with a lever valve in the cab. The high-pressure cylinder saddle is made in two pieces,the upper of which is riveted to the boiler shell, while thelower is cored out for the intercepting valve and pipe connec-tions. .\11 six cylinders are cast from the same pattern; theyare of vanadium iron, so designed that bushings 14 in. thickcan be applied subsequently if desired. The pistons havedished heads of forged steel, with cast iron bull rings heldin place by electrically welded retaining rings. The pistonrods are of Nikrome steel, without extensions. Vanadiumcast steel is used for the cross-bead bodies; they are of theLaird type, and are as light as is consistent with the strengthrequired. The main crank pins are of Nikrome steel, hollowbored, while the main and side rods and main driving axlesare of chrome-vanadium heat treated steel. Vanadium steel 64. /ay; Total Weight, 844,000 lb.; Tractive Effort, 166,300 lb.
