MŽ Series 411
The MŽ class 411 is an electric multiple unit built for Makedonski Železnici by CRRC Zhuzhou Locomotive CRRC Zhuzhou Locomotive Co., Ltd. is one of the electric locomotive manufacturers in China. It is one of the subsidiaries of CRRC. History Predecessor Zhuzhou Electric Locomotive Works was founded in 1936. CRRC Zhuzhou Locomotive Co., .... History Two three-car Class 411 EMUs have been built by CRRC under a contract signed in June 2014. The railway announced in June 2019 that the units have had electrical problems, which the manufacturer refuses to fix under warranty. There have also been issues with procuring spare parts, as the costs of shipping the items from China exceed the value of the parts themselves The units were financed in part with a €25 million loan from the European Bank for Reconstruction & Development. Technical specifications Voltage This train set utilises 25 kV/50 Hz AC. References {{DEFAULTSORT:MŽ series 411 Electric mult ...

CRRC Zhuzhou Locomotive
CRRC Zhuzhou Locomotive Co., Ltd. is one of the electric locomotive manufacturers in China. It is one of the subsidiaries of CRRC. History Predecessor Zhuzhou Electric Locomotive Works was founded in 1936. CRRC Zhuzhou Locomotive Co., Ltd. On 31 August 2005, CSR Group Zhuzhou Electric Locomotive Co., Ltd. was spin-off from the locomotive works; the original legal entity of the locomotive works became an intermediate holding company for CSR Group only. After the formation of the listed company CSR Corporation Limited, the limited company "CSR Group Zhuzhou Electric Locomotive" became part of the listed portion of the group, and the intermediate holding company remained unlisted. The limited company also renamed to CSR Zhuzhou Electric Locomotive Co., Ltd.. In 2015 the company was renamed into CRRC Zhuzhou Locomotive Co., Ltd. ().

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. Other types of current collectors include the bow collector and the trolley pole. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad. The familiar diamond-shaped roller pantograph was devised and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 KV/50 Hz AC
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The development of 25kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s. One of the reasons it was not introduced earlier was the lack of suitable small and lightweight control and rectification equipment before the development of solid-state rectifiers and related technology. Another reason was the increased clearance required under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearance to live parts.
