INDIAN RAILWAYS IS BIGGEST RAIL SYSTEM IN ASIA AND SECOND BIGGEST IN THE WORLD
ADVENT OF ELECTRIC TRACTION IN INDIA ON 3rd FEB ,1925 10:00 AM. • INDIA BECOMES 24th SUCH NATION IN THE WORLD • TO RUN BETWEEN BORIBUNDER TO KURLA, THE IST ELECTRIC TRAIN IN INDIA WAS FLAGGED OFF BY THE THEN GOVERNOR OF BOMBAY, SIR LESLIE WILSON
INTRODUCTION OF ELECTRIC TRACTION AND LOCOMOTIVES IN INDIA • * IN INDIA FIRST ELECTRIFICATION ON 1500 VOLT • D.C UNDERTAKEN BETWEEN (1925- 1932) • * THIS INCLUDED : • 304 ROUTE KMS BETWEEN BOMBAY TO IGATPURI AND PUNE • 62 ROUTE KMS BETWEEN CHURCHGATE AND VIRAR • 32 ROUTE KMS BETWEEN MADRAS BEACH AND TAMBARAM
* LOCOMOTIVES WERE FURTHER CLASSIFIED AS FREIGHT AND PASSENGER. FREIGHT LOCOMOTIVES WERE DESIGNED TO HAUL MORE LOAD AND PASSENGER LOCOMOTIVE TO HAUL AT GREATER SPEEDS. • * ELECTRIC TRACTION HAD NOW COME TO STAY IN INDIA FOR ALL FORSEEABLE FUTURE.

CLASSIFICATION OF ELECTRIC LOCOMOTIVES GAUGE The first letter stands for gauge ‘W’ for broad Gauge ( 1676 mm ) – BG ‘Y’ for meter Gauge ( 1000 mm ) –MG MOTIVE POWER SOURCE The second letter stands for motive power source. ‘C’ for dc ‘A’ for ac ‘B’ for battery
CLASSIFICATION OF ELECTRIC LOCOMOTIVES SERVICE The third letter stands for type of service ‘P’ for Passenger ‘G’ for Goods ‘M’ for Mixed ‘S’ for shunting INDIVIDUAL DESIGN The number stands for various individual design EX 20xxx,21XXX ---- WAM4,WAM1,2,3 WAG1,2,3,4 23XXX ---- WAG5 24XXX ----- WAG5H BHEL 244xx---- WAG5 CLW 26XXX ---- WAG6 27,28XXX ---- WAG7 31XXX ---- WAG9 22XXX ---- WAP1,4 30XXX ---- WAP5,7
First electric loco with the now familiar Co-Co wheel arrangement to be used in India large size and unusually long hoods position of the entrance in the middle of the loco body side. used on superfast trains such as the Indrayani Exp. until quite recently (the 1990's). rarely used for freight There are now two of these left, which were homed at Kalyan WCM-1
WCM-2 • Slightly smaller than the WCM-1 • normally positioned entrance doors • initially built to run on the 3kV DC sections in the Calcutta area • several were still in service until the 1980s • Four of these are still in use on the Mumbai-Igatpuri route; for the Pune-Karjat shuttle. Homed at Kalyan
WCM-3 • smallest of the WCM series • built for the 3kV Calcutta area and later converted to run on 1.5kV DC • separate light enclosures for the parking / marker lights (next to the headlight) and the tail lamps (just above the buffers). • Later used mostly for freight.
WAM-1 • first AC electrics to run in India • mostly deployed by ER in the Howrah-Asansol-Dhanbad-Mughalsarai section • Fully suspended TM coupled to axle through “Jaquemin” drive • Super structure is connected to bogie through pendular suspention and low traction bars • Water cooled Ignitron Rectifiers • Mostly used for non-express passenger trains, but some were used double-headed for freight service • Some were still [12/98] in operation on ER (Sealdah-Lalgola passenger, etc.).
Type- WCM 4 - BROAD GAUGE 1500 V D.C LOCOMOTIVE FOR MIXED TRAFFIC • ( PHOTOGRAPHED IN 1980 AT LONAWALA ) • Year – 1960 • Make – HITACHI • Power - 3290 HP • Bogie arrangement – Co-Co • Max speed – 120 KMPH • Weight – 125 (t)
WCM-4 • larger and more powerful versions of the WCM-3 • Initially used to haul superfasts and other express trains, but relegated to freight operations due to technical difficulties • only WCM series locos to be used almost exclusively for freight duties • last imported engines to come with bonnets (noses) at either end
Type- WCM5 BROAD GAUGE 1500 V D.C LOCOMOTIVE FOR MIXED TRAFFIC • Year – 1961 • Make – CLW • Power – 3170 HP • Weight – 124 (t) • Bogie arrangement – Co-Co • Max speed –120 KMPH • FIRST ENGINE FROM CLW WAS NAMED “ LOKMANYA ’’ AND NUMBERED 20083.
WCM-5 • India's first indigenously designed DC electric Locos • In the WCM series, these are the first to use half-collector pantographs • Mostly used for passenger duties
WAM-2 • Motor is coupled to axle through a flexible WN gear drive • repeat order of 28 No. of locomotives was placed to meet the requirement of push-pull operation for suburban trains • first batch of 10 locos had air brakes for the loco and vacuum train brakes, and the second batch of 26 had only vacuum brakes. • used on ER, and sometimes ran all the way to New Delhi via Kanpur • They were also used double-headed for freight trains
WAM-3 • Only two of these locos existed (both at Asansol; 20333, and 20337). • basically the same as WAM-2 locos, but with reversed pantographs and Mitsubishi traction motors from a different batch, and silicon rectifiers instead of ignitrons • used to haul the Kalka Mail, Toofan Exp., Amritsar Exp. at first, and then when the WAM-4P and other variants arrived they were relegated to hauling lower priority trains such as the Sealdah-Lalgola Pass. or the Howrah-Azimgunj Pass • By Jan. 2000, they were used to shunting duties at the Asansol shed
WAG1 WAG-1, WAG/1 • 42 no. ordered(07.04.1961) to EG(5 completely assembled in Europe, remaining in CLW) • Monomoter bogie (resulted in considerable saving in weight in traction equipment giving better adhesion) • Repeat order placed(14.11.1963) for 20 Locos(8 completely built in Europe, bogies for remaining 12 built in CLW) • The first one built in India in Nov. 16, 1963. Two units (the last ones) built by CLW in 1964 • Decommissioned by 2002 WAG1
WAG-2 • Just after they were imported from Japan, they were based at Asansol shed of ER and transferred to Bhusawal and Itarsi sheds of CR in 1985. • Bhuawal had large numbers of them into the 1990s
WAG-3 • Fully suspended TM, permanently grouped in parallel • Monomotor bogie
YAM-1 • Speed control is achieved by LT tap changer provided in transformer secondary • Two bogie mounted TM
