Railway and Locomotive Engineering . ts atthe engine truck and the first driver arejust about the same in amount.

As faras guiding the engine is concerned, there-fore, the arrangement is very similar toa four-wheel truck application with the fleet, thus preventing the cramping of thedriving wheel base in the curve and ex-cess pressure upon the driving wheelflanges.
