India Expands Rail Corridors to Ease Congestion
Indian Railways is working to make its busiest train routes better.
These routes, called High Density Networks (HDNs), carry a lot of passengers and goods but are often too crowded.
The government has approved building new tracks, like adding a third and fourth line to a busy section near Mumbai.
This will help trains run on time and carry more people and goods.
Right now, some parts of these routes are used way more than they should be, which causes delays.
Indian Railways plans to keep improving these routes to make train travel smoother and more efficient.
Indian Railways is expanding its High Density Network (HDN) corridors to reduce congestion.
The government approved a third and fourth line on the Badlapur-Karjat section in Maharashtra.
HDN corridors make up 16% of the network but handle 41% of the total rail traffic.
Current capacity utilization in HDN is high, with 14.11% of the network operating above 150% capacity.
Plans include upgrading HDN corridors to triple or quadruple lines to meet future demand.
