Thegear is mounted on a quill shaft, which is also supportedon the locomotive frame, and which surrounds the locomotiveaxle witli an appreciable clearance. The connection betweenthe driving wheel and the quill shaft is made by end of each spring is connected to the quill shaft, whilethe otlier engages a bracket on the spoke of the driving wheel. This arrangement permits the driving wheels to followthe unevenness of the roadbed, without affecting gear mesh,as well as cushioning the torque of the motor.

In the designof this type of quill shaft the details have been governed bythe experience obtained from the successful application of asimilar type of drive on the New York, New Haven & Hart-ford locomotives, making due allowance for the increase intractive effort.

The main driving motors areseries motors, and in order to make them regenerate powerto the line it is necessarj that they be separately control of the excitation of the main motors for re-generation is initiated manually by the operator from themaster controller, the exciting current coming from two smallgenerators geared to one of the axles of each bogie small generators in turn are excited from an indepen-dent source, consisting of a motor-generator set operatingin parallel with a small storage batter)-. All of the mainmotors are used during regeneration. Efforts have beenmade in the design of main motors and the axle generatorsto guard against anv possibility of snow getting into thewindings. One of the axle generators is mounted on eachbogie truck in a standard street railway
