END VIEW OF CAR AND SWITCH the switches and light the car. This is the operation also at start-ing. The car is of the Duplex type, manufactured by the Duplex CarCompany, of New York, and has attracted much favorable com-ment by its tasteful appearance when open and closed. The en-gravings on page 260 show it in both conditions. The car ismounted on iwo Peckham 14-A trucks, equipped with G. E. 1000motors with standard controller, with the exception that one con-tact is changed. The car carries ten cells of storage batteries andthe rotary transformer required by this system. Both of theseare located underneath the car so as to take up no space availablefor passengers. To demonstrate the reliability of the system under adverse con-ditions, the road has been subjected to very severe tests. One ofthese tests was that of covering the road for a distance of 25 ft.with closely packed and wet snow heaped to a height of severalinches above the track, entirely hiding the three rails from view.Th
