DS3 (locomotive)
The DS3 ( uk, ДС3) is an AC electric locomotive manufactured by Dnipropetrovsk research-and-production association for electric locomotive engineering (NPO DEVZ) jointly with Siemens. ( uk, Дніпропетровський електровозобудівний завод, ) Equipment Siemens provided the power electronics while DEVZ produced the chassis, traction motor A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles (ele ...s, auxiliary machinery etc. Use The DS3 was designed as a dual-purpose locomotive for both passenger and freight service, but now is used primarily for pulling express passenger trains.

Vinnytsia
Vinnytsia ( ; uk, Вінниця, ; yi, װיניצע) is a city in west-central Ukraine, located on the banks of the Southern Bug. It is the administrative center of Vinnytsia Oblast and the largest city in the historic region of Podillia. Administratively, it is incorporated as a town of oblast significance. It also serves as an administrative center of Vinnytsia Raion, one of the 6 districts of Vinnytsia Oblast, though it is not a part of the district. It has a population of . The city's roots date back to the Middle Ages. It was under Lithuanian and Polish control for centuries until the Russian Empire annexed it in 1793. During the 1930s and early 1940s the city was the site of massacres, first during Stalin's purges and then during the Holocaust in Ukraine and the Nazi occupation. A Cold War–era airbase was located near the city. Name The name of Vinnytsia appeared for the first time in 1363. It is assumed that the name is derived from the old Slavic word "Vino", ...

ALSN
ALSN (Автоматическая локомотивная сигнализация непрерывная, in Latin - Avtomaticheskaya Lokomotivnaya Signalizatsiya Nepreryvnaya, meaning ''Continuous Automatic Train Signalling'') is a train control system used widely on the main lines of the ex-Soviet states (Russian Federation, Ukraine, Belarus, Latvia, Lithuania, Estonia). It uses modulated pulses inducted into rails similar to the Italian RS4 Codici and American Pulse Code Cab Signaling. On high-speed lines the variant ALS-EN (АЛС-ЕН) is used which takes advantage of a double phase difference modulation of the carrier wave. The name ALSN (АЛСН - автоматическая локомотивная сигнализация непрерывного действия) is composed of ALS, literally "Automatic Locomotive Signalling" (АЛС - автоматическая локомотивная сигнализация) and the variant designation N "Continuous Effect" ( ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...

Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles (electric multiple units) and other electric vehicles including electric milk floats, elevators, roller coasters, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems (Diesel locomotive#Transmission types, diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control DC motor, Direct-current motors with series Field coil, field windings are the oldest type of traction motors. These provide a speed-torque characteristic useful for propulsion, providing high torque at lower speeds for acceleration of the vehicle, and declining torque as speed increases. By arranging the field winding with multiple taps, the speed characteristic can be varied, allowing relatively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 KV AC Locomotives
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the for ...

Railway Locomotives Introduced In 2003
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...
