The Amstegplant would contain five 7500-hp turbo-generator setsand two groups of exciters. TRANSMISSION AND DISTRIBUTION Part of the contact line would be supplied with en-ergy directly from 16,000-volt, single-phase genera-tors, and part would be supplied at the same potentialfrom 45,000/16,000-volt transformer substations at. Fig. 6—Swiss Report—Map of the Gothard Line, Showing Section to Be Electrified, Location of Proposed Power Plants,Transformer Substations and Shops; also Connecting Standard-Gage Lines The changes necessary to adapt the shops for electricrolling stock have also been considered. Provision hasbeen made to maintain the railway telegraph lines at20 m ( ft.) from the right-of-way, while the federaltelegraphs would be located at a somewhat greater dis-tance but within sight of the railway.
