Diesel Loco Modernisation Works, Patiala (DMW) achieves highest ever production of new Electric Locomotives and Diesel Electric Tower Cars (DETCs). Despite pandemic restrictions, DMW produced are cord number of 53 WAP-7 passenger locos, 3 WAG-9HC freight Locos, 77 DETCs (Diesel Electric Tower Cars) and one WAG-10 converted Electric Loco (Total 134 vehicles) during 2020-21 against 129 vehicles produced last year. 

  • Besides this, DMW also supplied 144 Motorized Bogies and 122 Motorized Wheel sets to Zonal Railways for their maintenance requirements,achieving a total production output of Rs.1735.20 Crs. during 2020-21. 
  • Attuning Itself to the Indian Railways’ goal of complete electrification, DMW started manufacturing of new 3-Phase IGBT based WAP7 locomotives and 8-Wheeler Diesel Electric Tower Cars (DETC) in the month of February and December 2018 respectively. 
  • Till March’21, DMW has manufactured 194 WAP-7 passenger locomotives and 127 Diesel Electric Tower Cars, which are self propelled vehicles used for electrification and maintenance activities of railways. 
  • Diversifying it’s product-mix, DMW has also started series production of WAG-9HC freight locomotives and the 1st WAG-9HC locomotive has been turned out in Mar’2021. 
  • The first prototype WAG 10 electric loco, which is converted from diesel locos, has also been turned out in March 2021.
  • Principal Chief Administrative Officer, DMW Patiala, Shri S.N.Dubey, applauded the efforts of the staff, supervisors and officers of DMW and congratulated them for this remarkable achievement despite the challenging work conditions caused by COVID-19 pandemic during 2020-21

First WAG- 9HC Electric Locomotive manufactured by DMW:

Meanwhile, under the ‘Make in India’ initiative, Diesel Loco Modernisation Works, Patiala has successfully manufactured its first state-of-the-art computer controlled 6000 HP 3-phase freight WAG-9HC locomotive no. 41501 and turned it out on 24th March, 2021 to East Central Railways, Gomo.

  • The manufacturing of 3-phase Electric Locomotives is a major step towards saving traction energy cost and also cut down on carbon emissions because such locomotives are more energy efficient and regenerates electrical energy while braking by converting the kinetic energy into electrical energy and feed it back to the Railway OHE network for powering other nearby Electric Engines in Railway network.
  • The weight of this locomotive is 132 tonnes and has a higher starting tractive effort of 510 kN. 
  • The maximum allowed speed of 100 Kmph under specified conditions of Railway Track. 
  • This locomotive is equipped with state of the art IGBT based energy efficient Power Converters as well as Auxiliary Converters. 
  • The crew cabins are fully air conditioned as both cabins are equipped with Roof Mounted Cab ACs. 
  • To enhance the haulage capacity, these locomotives can be used in multi operation also where two multi loco unit.
