E129 Series
The is a DC electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) on local services in the Niigata area since 6 December 2014. Design Built at the J-TREC factory in Niitsu, Niigata, the stainless steel body and "universal design" interior is derived from the E233 series commuter EMU.

Dynamic Braking
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electr ...

Shinonoi Line
The is a railway line in Nagano Prefecture, Japan, operated by the East Japan Railway Company (JR East). It connects Shinonoi Station in Nagano with Shiojiri Station in Shiojiri. The line is a corridor between the Shinetsu Main Line and the Chūō Main Line. All the limited express trains on the Shinonoi Line come from the Chūō Main Line: '' Azusa'' from Tokyo and '' Shinano'' from Nagoya. Stations All stations are located in Nagano Prefecture. :●: All trains stop, ▲: Some trains stop, ｜: non-stop, Rapid ''Misuzu'' stops at all stations Passing loops and switchbacks Hirase loop A passing loop is located in Azumino, known as .

Utsunomiya Line
The Utsunomiya Line ( ja, 宇都宮線, ) is the name given to a 163.5 kilometer section of the Tōhoku Main Line between Tokyo Station in Tokyo and Kuroiso Station in Nasushiobara, Tochigi, Japan. It is part of the East Japan Railway Company (JR East) network. Services Services on the Utsunomiya Line are typically divided into three categories: services to or from Ueno, Shōnan–Shinjuku Line services, and Ueno–Tokyo Line services. Between Ueno and Ōmiya, trains share the track with the Takasaki Line, both of which serve as ''de facto'' express services compared to the parallel Keihin–Tōhoku Line. Northbound services mostly terminate at or , with some at . Southbound trains mostly travel through the Shōnan–Shinjuku Line to on the Yokosuka Line, or the Ueno–Tokyo Line to on the Tōkaidō Line, with a few trains terminating at Ueno. The fastest service on the line, the rapid ''Rabbit'', makes the run between Ueno and Utsunomiya in 1 hour and 26 minutes. Serv ...

Takasaki Line
The Takasaki Line ( ja, 高崎線, ) is a Japanese railway line which connects Ōmiya Station in Saitama, Saitama Prefecture and Takasaki Station in Takasaki, Gunma Prefecture. It is owned and operated by the East Japan Railway Company (JR East). All services on the line (excluding through Shonan-Shinjuku Line trains) run to/from Ueno Station in Tokyo via the Tōhoku Main Line. The line was extended to Tokyo Station via the Ueno-Tokyo Line that opened in March 2015. As the Takasaki Line serves many major cities within Saitama Prefecture, it is a vital means of transport within the prefecture. National Route 17 and its historical predecessor, the Nakasendō, run parallel to the line. Services Services on the Takasaki Line are typically divided into three categories: services to or from Ueno, Shōnan-Shinjuku Line services, and Ueno-Tokyo Line services. Between Ueno and Ōmiya, trains share the track with the Tōhoku Main Line (Utsunomiya Line), both of which serve as ''de f ...

Japanese National Railways
The abbreviated JNR or , was the business entity that operated Japan's national railway network from 1949 to 1987. Network Railways As of June 1, 1949, the date of establishment of JNR, it operated of narrow gauge () railways in all 46 prefectures of Japan. This figure expanded to in 1981 (excluding Shinkansen), but later reduced to as of March 31, 1987, the last day of JNR. JNR operated both passenger and freight services. Shinkansen Shinkansen, the world's first high-speed railway was debuted by JNR in 1964. By the end of JNR in 1987, four lines were constructed: ; Tōkaidō Shinkansen: , completed in 1964 ; Sanyō Shinkansen: , completed in 1975 ; Tōhoku Shinkansen: , as of 1987 ; Jōetsu Shinkansen: , completed in 1982 Buses JNR operated bus lines as feeders, supplements or substitutions of railways. Unlike railway operation, JNR Bus was not superior to other local bus operators. The JR Bus companies are the successors of the bus operation of JNR. Ships JNR ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ex ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or '' voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power ...
