Indian Railways approved multitracking of the 29 km Danapur-Fatuha section of East Central Railway in Bihar at a cost of Rs 976 crore.
Third and fourth lines will be laid between Danapur and Patna and between Patna Saheb and Fatuha, with a third line between Rajendra Nagar and Patna Saheb.
In its first year the project will allow 22 additional passenger trains and 18 additional freight trains daily.
It will enable handling of an additional 5.2 million tonnes per annum of freight traffic.
The section forms part of the quadrupling of the Delhi-Deen Dayal Upadhyaya Junction-Patna-Kiul-Bhagalpur-Khanna-Howrah route under the Energy, Mineral and Cement Corridor.
A single-line section forces trains travelling in opposite directions to wait at crossing stations. Doubling gives each direction its own track. Adding a third and fourth line goes further, allowing slow freight and fast passenger services to be separated onto different tracks so that neither delays the other. Because it uses land the railway already owns along the existing alignment, multitracking is far cheaper per unit of capacity than building a new line, which is why it is the standard remedy for saturated corridors.
Simple Analogy: It is the difference between a two-lane road where every truck holds up the cars behind it and a four-lane highway where slow and fast traffic each get their own lane.
