FIG. 4.—METHOD OF ELECTRICALLY CONNECTING THIRD RAILAT CROSSINGS places are simply laid in wooden troughs, which are filled withasphalt. The same wooden trenches are used for the connect-ing feeders of the third rail. GENERA 11NG STATIONSThere are two .o-eneratin^ stations, situated respectively at Servoz and Chavants, asshown on the map. Fig. is by direct cur-rent, but high-tension distri-bution with sub-stations willprobably be used for feedingthe extension of the line nowunder construction. Both stations are hydraulicand derive their power fromthe River Arve, the valley ofwhich is followed by the linefor some considerable dis-tance. The water of the ArveRiver is turbid and muddy,and special care had to betaken on this accou
