The First battery-operated dual-mode locomotive 'Navdoot’

  • Published
    18th May, 2022

   The West central railway (WCR) has developed battery-operated dual-mode locomotive 'Navdoot'.

  • It is running between Jabalpur, Mudwara and other stations on trial basis.

About ‘Navdoot’

  •   This engine runs on both modes i.e. battery and electricity. 
  •   This e-engine can pull 18 coaches at a speed of 30 kmph. 
  •   It has 84 batteries and has a capacity to pull 400 tonnes at present.
  •   This has been developed by the Electric Department of New Katni Junction.


  •   This Dual Mode Locomotive has also received the’ Best Innovation Award’ from the Railway Board.
  •   Railways will save 1000 litres of diesel every day with this new locomotive.
  •   After clearing all the trials, it will be used more widely in other stations for purposes like carrying goods, coal, oil tankers etc.

Types of electric vehicles in India

  • Battery Electric Vehicle (BEV): Fully powered by electricity. These are more efficient compared to hybrid and plug-in hybrids.
  • Hybrid Electric Vehicle:
    • Hybrid Electric Vehicle (HEV): The vehicle uses both the internal combustion (usually petrol) engine and the battery-powered motor powertrain. The petrol engine is used both to drive and charge when the battery is empty. These vehicles are not as efficient as fully electric or plug-in hybrid vehicles.
    • Plug-in Hybrid Electric Vehicle (PHEV): Uses both an internal combustion engine and a battery charged from an external socket (they have a plug). This means the vehicle’s battery can be charged with electricity rather than the engine. PHEVs are more efficient than HEVs but less efficient than BEVs.
  • Fuel Cell Electric Vehicle (FCEV): Electric energy is produced from chemical energy. For example, a hydrogen FCEV.

Associated agencies

  •   Ministry of Power: The Electric Vehicle industry in India is far behind, with less than 1% of the total vehicle sales.
    • Currently, Indian roads are dominated by conventional vehicles and have approximately 0.4 million electric two-wheelers and a few thousand electric cars only.
    • The Indian EV industry has been on the back seat due to various challenges.
    • The government of India have undertaken multiple initiatives to promote manufacturing and adoption of electric vehicles in India.
    • With support of the government, electric vehicles have started penetrating in the Indian market.
    • However, availability of adequate Charging Infrastructure is one of the key requirements for accelerated adoption of electric vehicles in India.
