Indian Railways (IR) has envisioned to achieve net zero carbon emission by 2030. Following measures have, inter-alia, been undertaken in this regard:

  1. 100% Electrification of Broad Gauge (BG) Railway network.
  2. About 142 Mega Watt (MW) of solar plants (both on Rooftops and on its vacant land) and about 103 MW of Wind power plants have been commissioned (till 31.10.2022).
  3. Use of Insulated Gate Bipolar Transistor (IGBT) based 3-phase propulsion system with regenerative braking in locomotives, Electrical Multiple Unit (EMU) trains, Mainline Electric Multiple Unit (MEMU) trains, Kolkata Metro rakes and Electric train sets.
  4. Conversion of End on Generation (EOG) trains into Head on Generation (HOG) trains to reduce noise, air pollution and diesel consumption.
  5. Provision of Light emitting diode (LED) lighting in all Railway installations including Railway stations, service buildings, Residential quarters and coaches for reduction in electricity consumption.
  6. Afforestation of railway land to increase carbon sink.
  7. Green Certifications- Green Certifications of various industrial units, railway stations and other railway establishments have been done. Further, Environment Management System (EMS): ISO 14001 certification of various railway stations has also been done.
  8. Construction of Eastern and Western Dedicated Freight Corridors (DFCs).
  9. Installation of waste to energy plants.
  10. Further, IR has decided to progressively procure renewable energy to reduce energy consumption through conventional sources.

At present, there is no proposal to induct solar train in the Railway fleet. The solar system works during the day time and generate battery backup of approximately 4 to 5 hours. System does not work properly during fog/rain and winter season and battery backup goes down to 2 to 3 hours depending upon weather conditions. Therefore, the system has not been pursued further.
