Hello guys , i am back with a new video,This video available in english, so watch that video too 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 parcels and 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 extra equipment needed to transmit electric power to the train can be difficult. EMUs, when compared with electric locomotives, offer Higher acceleration, since there are more motors sharing the same load Eddy current, rheostatic and regenerative braking on multiple axles at once, greatly reducing wear on brake pads and/or shoes and allowing for faster braking (lower/reduced braking distances) Reduced axle loads, since the need for a heavy locomotive is eliminated; this in turn allows for simpler and cheaper structures that use less material (like bridges and viaducts) and lower structure maintenance costs Reduced ground vibrations, due to the above Lower adhesion coefficients for driving axles A higher degree of redundancy - performance is only minimally affected following the failure of a single motor Higher seating capacity, since there is no locomotive; all cars can contain seats. While electric locomotives, when compared to EMUs, offer: Less electrical equipment per train resulting in lower train manufacturing and maintenance costs Easily allows for lower noise and vibration in passenger cars, since there are no motors or gearboxes on the bogies below them MEMU The Mainline Electric Multiple Unit (MEMU) are electric multiple unit (EMU) trains that serve short and medium-distance routes in India, as compared to normal EMU trains ("local" trains) that connect urban and suburban areas. IR is progressively replacing all locomotive-hauled slow and fast passenger and intercity trains with EMUs. The upgraded trains are re-branded as MEMUs. MEMU are manufactured at Rail Coach Factory, Kapurthala, and Integral Coach Factory, Chennai. Rakes are maintained in the Titlagarh coach maintenance shops Video credits Nandha IRF Vetriselvan railfan SR fan LP Surya More information about Indian locomotives and trains checkout the channel Thanks for watching!!
