The Public Service Railway has just completed and put into operation in city service at Newark, N.J., a new car which embodies a number of interesting departures in construction and equipment from the type of car which has heretofore been considered the standard for this system.

The car body has a steel underframe built up entirely of structural shapes and plates, the 1-in. X 20-in. sill plates with reinforcing angles 2-1/2 in. X 2-1/2 in. X 3/8 in. at the bottom and plates 2-1/2 in. X 2-1/2 in. at the top taking the entire load. The cross-members serve to stiffen the frame and provide supports for the floor and apparatus under the car. The load is transmitted from the side sills to the trucks by cast-steel bolsters. The steel platform knees are hung on yokes bolted to the end sills, so that they may be easily removed in case a platform is damaged in an accident. Drawbar strains are transmitted directly to the bolsters through the center platform knees, which are attached to the bolster and to the drawhead.

The sill plates are stiffened by soft steel angles 2 in. X 1-1/2 in. X 1/8 in., which serve also as pockets for the ash side posts. The frame of the line car body above the sill plates is entirely of wood with the exception of the carlines supporting the roof, which are made of soft steel tees, 2 in. X 2 in. X 1/4 in.

The principal dimensions of the car are given in the table on page 115.

The most striking innovation on the car is the compromise-type roof. This is made of 3/8 in. Agasote in eight pieces molded at the factory to the shape required. The Agasote is bolted to the carlines and the joints are covered with canvas imbedded in white lead to make them water tight. To provide the necessary ventilation eight specially designed Automatic ventilators are installed on the roof. Hunter route signs of special design, built into the roof, are used to indicate the line over which the car is operating. Hunter destination signs are placed one on each platform and one on each side of the car at the rear end.

In the interior of the car two white-enameled iron pipes, one on each side of the car, are used to support the leather hand straps, which are covered with Rico sanitary hand-strap covers. The register rod and signal bell cord are installed one in each of the grab-strap pipes to eliminate troubles due to passengers ringing up fares and pulling the signal bell. Push buttons are installed on each post for passenger signal to motorman. The seats are longitudinal, one on each side of the car, and both the seats and backs are covered with canvas-lined rattan. As there are no doors, between the car body and the platform, the bulkhead is cut away as much as possible but still enough is left to protect the seated passengers from drafts when the doors are opened, and a white enamel grab handle is placed at each side for the convenience of passengers moving to and from the platforms.

The interior of the car is finished in natural cherry and gray white enamel, all of the woodwork being cherry and the inside of the roof, the carlines and all fitures above the advertising racks being enameled.

Light is provided in the car body by thirteen 23-watt Mazda lamps in a single row over the center of the aisle, and each platform has live additional lamps on separate circuits. Sixteen electric heaters thermostatically controlled are provided to heat the car body, and an additional heater is installed on each platform.

The platforms are arranged for pay-on-the-platform operation, a dividing rail separating the boarding from the alighting passengers and supporting the fare box and a stool which may be used by either motorman or conductor or swung out of the way. The register may be operated either by foot or by hand. The doors are all hand operated and fold inwardly, the entrance and exit doors being independent of each other. This is the standard platform arrangement for Public Service Raiway cars in city service. As there are no bulkhead doors in the car the motorman will not be allowed to open the platform window in cold weather, so that a double window was provided to prevent frosting on the inside.

The car is equipped with folding steps which operate in conjunction with the doors. These are of a new design, operated by cams, this method of operation being selected to insure the steps being in their lowest position before the doors are open wide enough to permit a passenger to pass through. This will eliminate accidents, which occur with other types of folding steps due to the passenger stepping on the tread when it is partially raised.

The electrical equipment consists of four Westinghouse 307-CA motors of 40 hp. each and HL control, the control being of the new type in which the switch group and reverser are combined in one unit. This is the first equipment of this type manufactured by the Westinghouse Electric & Manufacturing Company and put into service.

The trucks are the Standard Motor Truck Company's C-50-P having a 6-ft. 1-in. wheelbase and inside-hung motors. General Electric CP-27 compressor and straight air-brake equipment, and H.B. life guards complete the equipment. No arrangements have been made for train operation.
