CROSS SECTIONS OF SUBSTRUCTURE. the return circuit is carried by the rails which are provided withspecial joints and by a special conductor. These joints have two cop-per wires riveted to the rails and the return conductor is formed ofa bare copper wire 8 mm. in diameter, which is laid under ground.This runs the entire length of the line and is connected to the railsat every joint by means of the two wires mentioned. On part ofthe line the joints are provided with bonds which are soldered to theends of the rails, these bonds consisting, of two wires 5 mm. in di- ameter. Foi a distance of 500 ni. these two bond wires are con-nected to a I. inductor of 8 mm. in diameter and this conductor isriveted to tlic rail. The distribution on this part of the line is on the three-wire sys-tem ; two of the three conductors are overhead wires and the track

There is a difference of po-tential of 580 volts lietv.een each overhead wire and the track and1,160 volts Detween the two overhead wires. This system wasadopted with the object of reducing the section of the feeders be-tween the track and the central station and for avoiding the use ofa special return conductor. By this method only the difference incurrent carried by the two overhead wires is returned to the centralstation. Part of tho motor cars have a length between the axles of 1,800mm. and a total length of 8,500 mm. They provide for 18 seated and16 standing passengers. They are equipped with eight brake shoes.The cars which operate on the part of the line having heavy gradeshave a special system of brakes. On each of the two platforms ofthese cars is found a lever which operates steel shoes provided withpoints. On each side of the line alongside of the rails are laidwooden girders. The points on the sho
