In Indian Railways, A MEMU is an electric multiple unit (EMU) train that serves short and medium-distance routes in India, as compared to normal EMU trains that connect urban and suburban areas. The acronym stands for Mainline Electric Multiple Unit.[1]
History
[edit]Indian Railways (IR) started MEMU service on Asansol – Adra section on 15 July 1995 and on Kharagpur – Tata section on 22 July 1995. Delhi-Panipat MEMU service started on 27 September 1995. Raipur–Durg–Bhatapara–Raipur–Bilaspur MEMU service started on 17 October 1995. Arakkonam-Jolarpettai MEMU service on 22 May 2000. Bankura-Midnapore MEMU started on 30 June 2000. The first 20 coach MEMU ran between Surat to Virar in 2017. Since 2019, 3-phase MEMUs have started replacing existing MEMU rakes.[2]
IR is progressively replacing all locomotive-hauled slow and fast passenger and intercity trains with EMUs. The upgraded trains are re-branded as MEMUs.
Operation
[edit]The system uses multiple electrical units[3][4] operating on 25 kV AC drawn from overhead lines. The trailer coaches have two toilets for passengers and one for the crew.
The train can run up to 200 km (120 mi) between Eastern Ghat and Western Ghat. The rakes have a maximum permitted speed of 105 km/h (65 mph) on broad-gauge tracks. The motorcoaches use DC traction motors. These rakes use asynchronous traction motors and have a maximum designed speed of 110 km/h. These use a stainless steel body. Two of them operate on South Central Railways.
ICF launched new MEMUs capable to operate at 110–130 km/h. The construction cost is ₹ 26 crore per unit and can carry 2,618 passengers. This train has a three phase traction motor and operates on 25 kV current which saves 35% energy. It offers GPS-based passenger information systems and announcement in coaches. It has double leaf sliding doors, gangways, CCTV cameras and aluminium luggage racks. The driver's cabin has AC and the coach has an emergency communication facility. It is designed to operate between cities 200–300 km (120–190 mi) away in Uttar Pradesh. The train may start in February 2019.[5]
Manufacturing
[edit]MEMUs are manufactured at Rail Coach Factory, Kapurthala, and Integral Coach Factory, Chennai. Rakes are maintained in the Titlagarh coach maintenance shops.[citation needed] Marathwada Rail Coach Factory, Latur is currently trying to ramp up production capacity of 250 MEMU coaches per annum.
Third generation
[edit]New 3rd generation was rolled out from RCF Kapurthala with following features:
- Ethernet-based Train Control Management System which provides advanced control features
- designed for speeds of up to 110 kmph
- Energy efficient LED lights have been provided with 50 percent emergency lights in each coach
- train is equipped with the latest GPS-based public address and passenger information system in each coach to facilitate passengers with respect to railway stations enroute
- train is equipped with 3-phase IGBT-based converter and inverter designed and developed by BHEL
- train also features a technologically advanced regenerative braking system.
