In order to come within these require-ments and at the same time provide the proper counterbal-ance, the reciprocating parts were made of very light designand a special method was employed to secure an exact ad-justment of the counterweights in the driving wheels. Thedynamic augment requirements were met and by means ofcareful adjustment the proper counterbalance was securedfor the reciprocating w^eights. The boiler is of the extended wagon top t\pe, radiallystayed and fitted with a combustion chamber. The locomo-tives are equipped with superheaters and the reversing mech-anism is of the Lawson patented screw t)pe, which providesfor easy operation and is fitted with a positive locking de-vice and an indicator which shows the exact cut-off at whichthe engine is operated. The tender is of the six-wheel, rigid wheel base type, witliplate side frames, the journal boxes working in pedestalsrivet
