Journal de chemin de fer électrique . e le schéma supérieur montre les connexions pour la station Olivesubstation, et le second schéma les déchargeurs et les chariots fournis par cette sous-station et la sous-station Sherman. Le territoire entre les stations de métro se compose en grande partie d'un quartier résidentiel de haute classe appelé Hollywood. La plus grande partie de thetraffic sur les lignes de compagnie dans ce quartier est local, mais inclut également le service interurbain à la vallée de San fer-nando et aux stations balnéaires. L'introduction du système à trois fils n'a pas eu besoin de changements très importants dans les sous-stations et les chargeurs.

. Electric railway journal . e upper diagram shows the connections for the Olivesubstation, and the second diagram the arrangement offeeders and trolleys supplied from this substation andthe Sherman substation. The territory between thesesubstations consists largely of a high-class residentialdistrict called Hollywood. The largest part of thetraffic over the companys lines in this district is local, but includes also interurban service to the San Fer-nando Valley and to beach resorts. The introduction of the three-wire system did notrequire any very extensive changes in substations andfeeders. At Olive substation it involved nothing but afew changes in switchboard connections. At Shermansubstation it involved changes in switchboard connec-tions and the installation of a 400-kw. motor-generatorset. No additional feeders were required, but the oldfeeding system was rearranged somewhat and sectionalinsulators installed in the trolley wire. Between the IOOO K.W. 5TAMUEYM.& SET.M2 IOOOKWCE . M.«.
