Share with your network

The Central Government has issued Standard Specifications for MetroNeo suited for tier-2 cities or outer areas of tier-1/ mega cities, said Shri Durga Shanker Mishra, Secretary, Ministry of Housing & Urban Affairs.

He tweeted,”Happy to share that Ministry has issued Standard Specifications for MetroNeo suited for tier-2 cities or outer areas of tier-1/ mega cities with projected Per Hour Per Direction Traffic (PHPDT) for next two decades upto 10,000 today.”

“I am sure that MetroNeo will enable several other cities with population upto 5 lakh to aspire to get such viable mass rapid transit system as soon as possible. MetroNeo system will be formally launched by Hon’ble MoS(IC), MoHUA on 9th Nov, 2020 in UMI Conference,” he said in another tweet.

  • The metro rail system being developed at present is of high capacity which is required for bigger cities with very high ridership and Peak Hour Peak Direction Traffic (PHPDT).
  • Seeing the success of metro rail projects in the country, several other cities with lower projection of ridership and PHPDT are also aspiring for metro rail system.
  • Metro Neo system will be at much lesser cost, rail guided, rubber tyred electric coaches powered by overhead traction system running on a road slab (elevated/at-grade).
  • ‘Metroneo’ would also act as feeder system to high capacity Metro.
  • In addition to less capital cost, the operation and maintenance cost of Metroneo would also be less making the system more viable.

The Metroneo system for which the standards are appended below would be  suitable for mass transit corridors having a PHPDT upto 8000 with AW3 loading.
