Summer training report required by mechanical engineers who have done training in emu car shed for two months so that they present in college

EMU CAR shed is an industrial-technical setup, where repair and maintenance works of EMU & MEMU is carried out, so as to keep the loco working properly. It contributes to increase the operational life of EMU & MEMU and tries to minimize the line failures.  The shed consists of the infrastructure to berth, dismantle, repair and test the loco and subsystems.  The shed working is heavily based on the manual methods of doing the maintenance job and very less automation processes are used in sheds, especially in India.The EMU CAR shed usually has:-  Berths and platforms for loco maintenance.  Pits for under frame maintenance  Heavy lift cranes and lifting jacks  Fuel storage and lube oil storage, water treatment plant and testing labs etc.  Sub-assembly overhauling and repairing sections  Machine shop and welding facilities.
TYPES OF TRAINS IN EMU CAR SHED • There are three trains are inspection and maintenance in EMU CAR shed. These are as follow :- • 1. EMU • 2. MEMU • 3. DMU
1. EMU – In EMUs one power car (motor coach) is required for three coaches so for an EMU has 12 coaches in length will have 4 power cars & mainly runs in the suburban sections of major cities. It considered as normal local trains such as life line locals of MUMBAI, HYDERABAD, CHENNI etc. • 2. MEMU’s – In MEMUs one power car in needed for 4 coaches so MEMU are normally has 16-20 coaches long. It runs for long distance more than the suburban sections . It runs on the same line on which normal Local/Exp/Mail/SF trains runs. • MEMU – Vadodara – Ahmadabad MEMU • MEMU were modified EMU’s introduced in 1993-94 • 3. DEMU’s – In DEMU’s , generally runs on diesel which tank capacity about >4000lts. It named as overhead electric inspection car used in repair & maintenance of overhead cables which fitted above the roof of trains carries 25kv A.C supply.
