The superstructure ofthe car is built on T-irons bent in U-shape and forming, in onepiece, the side posts and the carlines. The sheathing is of steelplate and the floors are of two layers of wood armored on theunderside with steel plates. Ventilation is obtained by means of12 suction ventilators along the roof. The interior is divided into four compartments, the one atthe forward end being the engine room, behind which is a smallbaggage compartment, then a smoking compartment and a mainpassenger compartment taking up a large part of the body.

The interior of the car, with the excep-tion of the engine room, is finished in selected Mexican mahog-any. The seats are upholstered in leather and individual electriclights, one at each seat, furnish the artificial light. Exceptionally-good natural lighting is obtained by the very large double win-dows. There is no wood used in the engine compartment. The gasoline engine, which develops ioo brake horse-power at550 r. p. m., is direct connected to a direct current gen- 108 AMERICAN ENGINEER AND RAILROAD JOURNAL. erator, which furnishes current at variable voltage. This cur-rent is fed to the motors through the medium of a control sys-tem, by means of which the voltage of the generator may begoverned according to the requirements. Two motors are pro-vided, each being rated at 60 Engine.—The
