Another feature is ths axle bearinglining, the metal being chamfered off to clear altogetherthe fillet at the collar while a large bearing surfaceagainst the collar in a vertical plane is provided to takethe horizontal pressures set up under operating con-ditions. When tested on the stand the actual one-hour ratingof the motor is 190 hp. For acceleration a currentaveraging 250 amp. has been adopted. Under these. MOTORMANS AND TRAINMENS SWITCHBOARDS, THEFORMER PROVIDED WITH INTERLOCKED DOORSIN FRONT OF SWITCHES conditions the motor givesa tractive effort of about3500 lb. which in turn pro-vides an acceleration ofabout 1 Electro-pneumatic control has beeninstalled. These equip-ments, like other featuresof the new cars, have beenso designed that they willoperate in conjunction withthe control system fur-nished on the original effort has been made tohave a considerable numberof the parts entering intothe new design interchangewith those of the old. Ingeneral principle the newcontrol follows the arrange-ment of having all powercircuits made and brokenat a pneumatically rotateddrum which is mountedbeneath the car floor and which is governed in its move-ments by a master controller in the cab. No reversinghandle is provided for the latter, movement of the trainin the opposite direction being effected by movement ofthe main controller handle in the oppo
