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 WORLDTO 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 PUNE62 ROUTE KMS BETWEEN CHURCHGATE AND VIRAR32 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.

WAM-4first indigenously designed and built electric locoproduced until about 1997.This class proved so successful by virtue of its ruggedness suitable for Indian conditions and simplicity of maintenance, that IR used this basic design for a number of other locos later (WCAM-1, WAG-5A, WCG-2, and some WAP models).WAM-4B's were regeared versions for freight useWAM-4P locos are intended for passenger operationsWAM-4P D,WAM-4P DB 6P, WAM-4 6P DB HS, and WAM-4 6P D'D' - dual-brake'HS' - 'high speed'.'2S', '3P', '6P', etc. indicate traction motors connected in series or parallel

WAM-4most WAM-4's ended up hauling passenger trainshauling freight only in a few locations (Arakkonam - Renigunta, Kirandul-Kottavalasa and other SER sectionsMost of the WAM-4 locos now have their MU capability disabled as RDSO disapproves of these locos running MU'd over 100km/hfew WAM4s have been fitted for OHE monitoring by the Itarsi shed. They have CCTV cameras mounted on top of the headlamp assembly pointing towards the OHE and a separate lamp to illuminate the OHE. Monitors are installed inside the cabs. These locos even have rear view mirrors.

WAP-2Regeared versions of some WAM-2 locos, fitted into a WAP-1 shell. Bogies were improved versions of the WAM-2 bogies, allowing for somewhat higher speeds. These locos were found only on ER , from the early 1980s. There have been only 4 of these, and they were decommissioned in the late 1980s

WAP-3A variant of the WAP-1, originally classified WAP-1 FMII, produced in 1987 by CLW. There were 5 of these converted from WAP-1 locos. The first WAP-3 "Jawahar", #22005, Jan. 4, 1987) was used for the Taj Exp. for some time. Essentially the same as WAP-1 but with different Flexicoil bogies (Flexicoil Mark II for the earlier ones, and Flexicoil Mark 4 (fabricated bogies) for some of the later ones, etc.). Max. speed 140km/h.Note: All units have been converted back to the 'WAP-1' class (since about 1997).

WAG-6AUntil about 1993 they were the most powerful freight locos in IR's fleet.

The WAG-6 series locos are the only ones with 'vestibules' to connect between MU'd locos. WAG-6A locos have half-height vestibulesThe WAG-6A models are said to be upgradable to 160km/h but IR never tried this outSeparately excited DC TMMicroprocessor based control and fault indication systemCreep control system, comparing wheel speed with true ground speed permits maximum utilisation of available adhesion

WAP-4The need to run longer passenger trains (24 to 26 coaches as against the 19-coach capacity of the WAP-1 / WAP-3 locos), and also to eliminate the need for bankers in graded sections (e.g., the busy Itarsi-Nagpur section) led RDSO to consider an upgraded design of the WAP-1 loco and the WAP-4 loco design was published in November 1993. Indigenously designed, higher power rated silicon rectifiers and indigenously-designed 5400kVA transformerWeight kept to 112t by the use of aluminium plates, thinner underframe, and reducing some components such as sanders.

WAP-5These locos are intended for use with high-speed medium load trains such as the Rajdhani and Shatabdi trains, in contrast to the WAP-7 which is more powerful but which is intended for lower-speed haulage of heavier trainsProvision of taps from the main loco transformers for hotel load, pantry loads, wheel-mounted disc brakes, and a potential for speed enhancement to 200km/hBraking systems include regenerative braking (160kn), loco disc brakes, automatic train air brakesThe original design called for these locos to have air-conditioned cabs. The first units made by CLW do not have air-conditioned cabsPowered by 3-phase TMSpeed control is achieved by convertor/invertor control using GTO Thyristors Microprocessor based control and fault indication system

WAP-6This class is a variant of the WAP-4 designOne or two prototypes were built early from existing WAP-1 or WAP-4 locos using high-adhesion fabricated bogies (Flexicoil Mark IV) They are used for less prestigious trains such as the Amritsar Exp., Doon Exp., or Janata Expresses.

WAG-9These are essentially the same as the WAP-7 units, with some differences in gearing and the control software to make them suitable for freight operationsThe first few were imported from ABB (6 fully assembled and 16 in kit form (7 completely knocked down, the rest partially assembled), in 1996). In November 1998, CLW started producing these with indigenous components

WAP-7Identical to WAG-9 with modified gear ratio (72:20) and application softwareit is much heavier than the 78t WAP-5. Intended to haul heavier, 26-coach passenger trains and passenger/parcel mixed trains.Initial models were rated at 6125 hp total power and 33000 kgf (323kN) tractive effort.Modifications during continuing trials resulted in improved performance with the loco now yielding 6350 hp total power and 36000 kgf (352.8kN) tractive effort.

WDG-4The WDG4 locomotive is equipped with a turbocharged 16 cylinder 2-stroke 710 GB diesel engine This engine has high fuel efficiency and requires low maintenance. The fuel efficiency of this locomotive is around 11% better than the existing locomotives. This engine has many modern features like, laser hardened cylinder liners, unit fuel injectors which eliminate the problematic HP tube, Inconel valves, hydraulic valve adjuster, durable crankcase and piston The WDG4 locomotive is equipped with a high adhesion HTSC (High Tensile Steel Cast) truck or bogie
