Soon there was a demand for a model with an advanced AC drive system. The MP15AC replaced the MP15DC's DC generator with an alternator producing AC power which is converted to DC for the traction motors with a silicon rectifier. The MP15AC is 1.5 ft (457 mm) longer than an MP15DC, the extra space being needed for the rectifier equipment.
The MP15AC is 1.5 ft (457 mm) longer than an MP15DC, the extra space being needed for the rectifier equipment. The alternator-rectifier combination is more reliable than a generator, and this equipment became the standard for new diesel-electric locomotive designs.
In Japan on the Tokaido, Sanyo and Kyushu Shinkansen lines (using 1,435 mm or 4 ft 8 + 1 ⁄ 2 in gauge). In South Korea on the Korail network. In Taiwan on the Taiwan High Speed Rail line (using 1,435 mm or 4 ft 8 + 1 ⁄ 2 in gauge) and on Taiwan Railway Administration's electrified lines (using 1,067 mm or 3 ft 6 in gauge).
The centralized system is supplied by special power plants that generate 110 kV (or 132 kV in the Swiss system) AC at 16.7 Hz and by rotary converters or AC/AC converters that are supplied from the national power grid (e.g. 110 kV, 50 Hz), they convert it to 55-0-55 kV (or 66-0-66 kV) AC at 16.7 Hz.
Each container may be 9 ft 6 + 1 ⁄ 2 in (2.908 m) tall and the bottom of the well is 1 ft 2 in (0.36 m) above rail, making the overall height 20 ft 3 in (6.17 m) including the well car. [ 41 ] Electrification cost: electrification requires an entire new infrastructure to be built around the existing tracks at a significant cost.

Northern main line (connected to Czech Republic and Poland) and eastern lines (around Košice and Prešov), conversion to 25 kV AC planned, [10] and the broad gauge line between Košice and the Ukraine border (it will remain 3 kV until new broad gauge line construction, then convert to 25 kV AC), planned new broad gauge line is supposed to use ...
Usually applied for work above 1 kV AC 1.5 kV DC The primary classes are: [citation needed] Class 00 - phase to phase working voltage 500 V; Class 0 - phase to phase working voltage 1.0 kV; Class 1 - phase to phase working voltage 7.5 kV; Class 2 - phase to phase working voltage 17 kV; Class 3 - phase to phase working voltage 26.5 kV
