How WAG 12 locomotive will revolutionise freight operations in Indian Railways ?

WAG 12The first of the 12000-horsepower, WAG 12 electric locomotives has been put into commercial service by Indian Railways. Built by Alstom and certified by the Ministry of Railways and Commissioner of Railway Safety/RDSO. WAG-12 is the most powerful locomotives to run on Indian rails.

First 12000 HP made in India Locomotive, manufactured by Madhepura Electric Loco Factory situated in Bihar, was put into operation by Indian Railways.

The loco is named WAG12 with Number 60027. The train departed from Pt. Deen Dayal Upadhyaya Station at 14:08 hrs in long haul formation for Dhanbad Division of East Central Railway, consisting of 118 wagons.

Indian Railways has became 6th country in the world to join the elite club of producing high horse power locomotive indegenously.

Why WAG 12 is Special ?

These locomotives are state of art IGBT (Insulated Gate Bipolar Transistors) based, 3 phase drive, 9000 KW (12000 horse power) electric locomotive. The locomotive is capable of maximum tractive effort of 706 kN, which is capable of starting and running a 6000 T train in the gradient of 1 in 150. The locomotive with twin Bo-Bo design having 22.5 T (Tonnes) axle load is upgradable to 25 Tonnes with design speed of 120 kmph.

WAG 12 has two units, both are permanently coupled to each other and 2 outward facing cab. The locomotive will controlled from 1 working cab. Both units have been provided with a toilet for the crew.

This locomotive will be a game changer for further movement of coal trains for Dedicated Freight Corridor. The locomotives can be tracked through GPS for its strategic use through embedded software and Antennae being lifted through the servers on ground through microwave link.

The locomotive is capable of working on railway tracks with conventional OHE lines as well as on Dedicated Freight corridors with high rise OHE lines. The locomotive has air-conditioned driver cabs on either side. The locomotive is equipped with regenerative braking system which provides substantial energy savings during operations. These high horse power locomotives will help to decongest the saturated tracks by improving average speed of freight trains.

WAG 12 is set to revolutionise freight logistics in the country, the e-locos will allow faster and safer movement of heavy freight trains.

Madhepura Electric Locomotive Pvt. Ltd. (MELPL) will manufacture 800 State of the Art 12000 HP WAG 12 Electric Freight Locomotives in 11 years.


The project started in 2018 and the Prime Minister of India inaugurated the project on 10th April’ 2018. The prototype locomotive was delivered in March 2018. Based on the test results having design issues, the complete locomotive including bogies has been redesigned.

The new design of locomotive has been inspected by RDSO at Madhepura factory and cleared for dispatch from factory on 16th Nov’ 2019. Further RDSO has conducted oscillation trials at various speeds up to 132 kmph and the locomotive has passed oscillation trials successfully.
