The effect of these latter advantages is that sub-stations con-taining revolving machinery will not be required, in manyinstances no sub-stations at all, and in all cases where accelera-tion periods are frequent the energy saved by using this methodof speed regulation should effect considerable economy. Single-phase current at 6000 volts, 25 cycles, is conductedthrough an overhead wire suspended over the center of thetrack from one or two parallel steel wires, connected by crosswires spaced 3 m (10 ft.) apart. This construction, illustrated
