The Indian locomotive class '''WAG-11''' is a class of twin-section 25 [[Volt|kV]] [[Alternating current|AC]] [[Electric locomotive|electric locomotives]] that was developed in 2018 by [[Banaras Locomotive Works]] (BLW), Varanasi for [[Indian Railways]]. The model name stands for [[5 ft 6 in gauge railway|broad gauge (W)]], [[Alternating Current]] (A), Goods traffic (G), and 11th in series (11). They entered trials service in 2019. A total of 4 WAG-11 pairs have been built by [[Banaras Locomotive Works]] (BLW), Varanasi.
The Indian locomotive class '''WAG-11''' is a class of twin-section 25 [[Volt|kV]] [[Alternating current|AC]] [[electric locomotive]]s that was developed in 2018 by [[Banaras Locomotive Works]] (BLW), Varanasi for [[Indian Railways]]. This freight engine has been designed for a speed of 105&nbsp;km/h and weighs 252 tons. It is equipped with a three-phase induction motor, four power converters and regenerative as well as pneumatic braking system.<ref>{{cite news |last=Singh |first=Binay |date=8 January 2019 |title=World's first 12,000 HP converted electric locomotive rolls out |url=https://energy.economictimes.indiatimes.com/news/power/worlds-first-12000-hp-converted-electric-locomotive-rolls-out/67431945 |work=energy.economictimes.indiatimes.com |location= |access-date=26 August 2024 }}</ref> The model name stands for [[5 ft 6 in gauge railway|broad gauge (W)]], [[Alternating Current]] (A), Goods traffic (G), and 11th in series (11).

As of January 2020, 3 locomotives are built and are undergoing "testing", with further examples being converted from [[Indian locomotive class WDG-4|WDG-4]] to WAG-11.
As of January 2023, 4 locomotives are built and are undergoing "testing", with further examples being converted from [[Indian locomotive class WDG-4|WDG-4]] to WAG-11.

The same old GT46MAC (WDG-4)  traction motors are being used for WAG11. The locomotives had [[Gate turn-off thyristor|GTO]] propulsion, a few parts can not be leveraged for the rebuilt to [[Insulated-gate bipolar transistor|IGBT]] technology. However since the power supply now comes from the WAG9 transformer / control, [[Adtranz|ABB]] has been updating its WAG9 control software for the EMD 3 phase traction motors for best results.<ref>{{Cite web|title=WAG-11 traction|url=https://rdso.indianrailways.gov.in/works/uploads/File/MTR%20PCDO%20JUN%202018.pdf}}</ref>  As a result the diesel power pack of the locomotive will be decommissioned and used as spare parts for interim use since there are still 150+ more GTO WDG-4 in use.

There are quite a few differences between the two earlier prototypes of WAG11 and 29003. They are in the following lines:<ref>{{Cite web|title=Tender WAG-11|url=https://dlw.indianrailways.gov.in/works/uploads/File/EOI%20for%20coversion.pdf}}</ref>

* The loco shell is placed at the same height as a WAP7/WAG9 and is carefully covering the chassis. In earlier versions, the EMD chassis / under-frame was used and was visible. 29003 almost looks like it is made on WAG9 chassis / under-frame and EMD bogies/traction motors have been used.

The Indian locomotive class WAG-11 is a class of twin-section 25 kV AC electric locomotives that was developed in 2018 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. This freight engine has been designed for a speed of 105 km/h and weighs 252 tons. It is equipped with a three-phase induction motor, four power converters and regenerative as well as pneumatic braking system.[1] The model name stands for broad gauge (W), Alternating Current (A), Goods traffic (G), and 11th in series (11). They entered trials service in 2019. A total of 4 WAG-11 pairs have been built by Banaras Locomotive Works (BLW), Varanasi.

As of January 2023, 4 locomotives are built and are undergoing "testing", with further examples being converted from WDG-4 to WAG-11.

History[edit | edit source]

The history of WAG-11 begins in the early 2017 with the stated aim of the Indian Railways to minimize the dependence on diesel locomotives in Indian Railways after recommendation of Cabinet Committee on Economic Affairs (CCEA).[2][3] The committee recommended that Expansion of electrified routes across the country will also help in reducing energy cost.[4] Therefore, a large number of WDG-4 diesel locomotives would become surplus after full electrification.[5] Thus Indian Railways decided to convert existing WDG-4 locomotives which needed midlife overhaul into the WAG-11 electric locomotive class.

The same old GT46MAC (WDG-4) traction motors are being used for WAG-11. The locomotives had GTO propulsion, a few parts can not be leveraged for the rebuilt to IGBT technology. However, since the power supply now comes from the WAG9 transformer / control, ABB has been updating its WAG9 control software for the EMD 3 phase traction motors for best results.[6] As a result, the diesel power pack of the locomotive will be decommissioned and used as spare parts for interim use since there are still 150+ more GTO WDG-4 in use.

The first WAG-11 unit was allocated TKD for trials and performance monitoring.[7] They are fitted with high rise pantographs and have regenerative braking.[8] After initial testing another unit was built and these 2 locomotives were transferred to Bondamuda (BNDM) for examining working conditions hauling heavy load goods trains.[9] The third prototype pair came out of DLW shop but this pair is different from the previous two pairs because both of the locos have twin cabs and twin pantographs and are separately numbered: 29003 and 29004. It looks like they can be separately operated like any regular WAG-9. Also the height and construct of these two locos are extremely similar to WAG-9s.

Difference[edit | edit source]

There are quite a few differences between the two earlier prototypes of WAG-11 and 29003/29004. They are in the following lines:[10]

  • Instead of an articulated design, DLW made both locos as twin cab locos (they may be able to independently operated after decoupling)
  • Two pantographs each on both the locos - making is 4 pantographs for 29003 unit
  • The loco shell is placed at the same height as a WAP-7/WAG-9 and is carefully covering the chassis. In earlier versions, the EMD chassis / under-frame was used and was visible. 29003/29004 almost looks like they are made on WAG-9 chassis / under-frame and EMD bogies/traction motors have been used.
  • The cow-catcher is new and of typical WAP-7/WAG-9 net design. The solid EMD cowcatcher has been discontinued.
  • On top of the cabs, either a dynamic brake radiator or rooftop AC has been installed.

Comparison of three versions of WAG-11[11]
S.N. Version 1 (29001) Version 2 (29002) Version 3 (29003/29004)
1 Transformer mounted on board. Transfer under slung mounted. Transfer under slung mounted.
2 Transformer common to WAP-7/WAG-9. New design transformer used. Transformer common to WAG-9.
3 New equipment layout in which both power converters were on left side of loco. One before transformer other behind it. Equipment layout similar to WAG-9. Both power converters centrally placed above the transformer. Equipment layout similar to WAG-9.
4 Under slung battery box of WAG-9/WAP-7 used. Battery placed on board. Under slung battery box of WAG-9/WAP-7 used.
5 One end cab used. One end cab used. Both end cab with HVAC as in WAG-9.
6 Side wall modified from WAP-7 side wall and length increased by approx 3 metres. Side wall modified from WAP-7 side wall and length increased by approx 3 metres. Side wall and both cabs same as in WAG-9.
7 Roofs made in 5 parts due to location of power converter and MMD height. Roof made in 4 parts only as both the traction converters are placed centrally. Roof in 3 parts same as in WAP-7/WAG-9.
8 Underframe made by modifying WGD-4 underframe. Underframe made by modifying WGD-4 underframe. Underframe made by modifying WAP-7 underframe.
Advantages of WAG-11 (version 3) over WAG-11 with modified under-slung transformer:
  • No need to modify WDG-4 underframe, particularly partially cutting center sill, I-beam, and bottom plate.
  • Exactly similar layout of WAG-9 used.
  • Transformer common to WAG-9.
  • Can also work as a single unit.
  • Cost reduction due to use of complete shell similar to WAG-9 (with some changes for ensuring interfacing with WDG-4 MTA).
