In particular, the Gotthard Base Tunnel (opened on 1 June 2016) uses 15 kV, 16.7 Hz electrification. Due to high conversion costs, it is unlikely that existing 15 kV, 16.7 Hz systems will be converted to 25 kV, 50 Hz despite the fact that this would reduce the weight of the on-board step-down transformers to one third that of the present devices.
Converted in 1978 from Pennsylvania Railroad 11 kV 25 Hz system to the 12.5 kV 25 Hz on the Rahway-Matawan ROW and 12.5 kV 60 Hz electrification extended to Long Branch in 1988. The Matawan-Long Branch voltage converted from 12.5 kV 60 Hz system to the 25 kV 60 Hz in 2002. New Haven to Boston: Northeast Corridor (NEC), Amtrak
Map of the high voltage power grid used for power supply of electric railways in Germany, Switzerland and Austria. Germany, Austria and Switzerland operate the largest interconnected 15 kV 16.7 Hz system, which has central generation, a special transmission network, central and decentral converter plants.

Controls for the reclosers range from the original electromechanical systems to digital electronics with metering and SCADA functions. The ratings of reclosers run from 2.4–38 kV for load currents from 10–1200 A and fault currents from 1–16 kA. [7] [8] On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts.
Each motor has an own cooling blower. Two scissor-shaped pantographs collect the current of 15 kV / 16.7 Hz from the catenary. Recently, many of these pick-ups have been refitted as modern single-arm pantographs. The core of the electric system is the 3-blade main transformer with oil-cooling. The control unit has 30 power notches, semi ...
The Bombardier–Alstom HHP-8 (High Horse Power 8000) is a twin-cab electric locomotive built for Amtrak and MARC by a consortium of Bombardier and Alstom.Its electrical system was based on Alstom's BB 36000 locomotive.
