Cabinet approves eight railway multi-tracking projects costing ₹20,804 crore
The Cabinet Committee on Economic Affairs (CCEA) approved eight railway multi-tracking projects at a combined estimated cost of ₹20,804 crore, spanning 31 districts across nine states.
The projects will add approximately 1,196 route km to the Indian Railways network and are targeted for completion by 2029-30.
Five of the eight projects, worth ₹10,021 crore, cover Tamil Nadu, Andhra Pradesh, Karnataka, and Telangana — including third and fourth lines between Arakkonam and Renigunta (77 km) and between Whitefield and Bangarapet (47 km), doubling of the Hosur-Omalur (147 km) and Salem-Karur-Dindigul (159 km) sections, and multi-tracking of the Secunderabad (Ghatkesar)-Kazipet stretch (110 km).
The remaining three projects, worth ₹10,783 crore, cover West Bengal, Jharkhand, Odisha, Madhya Pradesh, and Chhattisgarh — comprising a fourth line between Kharagpur and Jharsuguda (Bagdehi), a fourth line between Katni and Pendra Road, and a third line between Bilaspur (Uslapur) and Pendra Road.
All eight projects have been sanctioned under the PM Gati Shakti National Master Plan framework, with the stated aim of improving multimodal connectivity and logistics efficiency.
PM Gati Shakti National Master Plan
PM Gati Shakti is a digital-platform-driven master plan for multimodal connectivity infrastructure, meant to integrate planning and implementation across ministries so that projects across different transport modes and economic zones are coordinated rather than executed in silos.
The Cabinet's own approval note frames all eight rail projects as sanctioned "under the PM Gati Shakti National Master Plan," making this a direct current-affairs illustration of how the platform is used to justify and coordinate large infrastructure investment decisions.
Cabinet Committee on Economic Affairs (CCEA)
The CCEA is the Union Cabinet's principal standing committee for economic decision-making, responsible for approving major investment proposals, projects with large financial outlays, and policies with significant economic implications — including capital-intensive railway and infrastructure projects.
The ₹20,804 crore approval is a textbook CCEA function — a large capital investment decision on Railways-sector infrastructure, routed through the specialised economic-affairs committee rather than a general Cabinet meeting.
Rail Line Multi-Tracking — Doubling, Third and Fourth Lines
"Multi-tracking" refers to adding additional parallel tracks (doubling, tripling, quadrupling) alongside an existing single or double railway line on the same route, as distinct from building an entirely new line (new BG line) on a fresh alignment. It is used to relieve congestion on saturated high-traffic corridors without acquiring a new right-of-way corridor.
Key Details
- Doubling: adding a second track to a single line; tripling/quadrupling (third/fourth lines): adding further parallel tracks where traffic density is very high (as in the Arakkonam-Renigunta and Whitefield-Bangarapet stretches here).
- Multi-tracking increases line capacity (more trains per hour) and reduces bottlenecks/section-average speed loss caused by mixed passenger-freight traffic sharing the same track.
- Distinguished from "gauge conversion" (changing track gauge, e.g., metre gauge to broad gauge) and "electrification" (adding overhead traction), which are separate categories of railway infrastructure projects, sometimes bundled in the same investment announcement.
All eight approved projects are explicitly multi-tracking works (doubling/third-fourth lines) rather than new lines, targeting congestion relief on already-existing corridors across nine states.
- Total project cost: ₹20,804 crore, across eight projects, 31 districts, nine states.
- Additional network length to be added: approximately 1,196 route km.
- Target completion: 2029-30.
- Southern cluster (five projects, ₹10,021 crore): Tamil Nadu, Andhra Pradesh, Karnataka, Telangana.
- Eastern/Central cluster (three projects, ₹10,783 crore): West Bengal, Jharkhand, Odisha, Madhya Pradesh, Chhattisgarh.
- Longest single stretch among the approved projects: Salem-Karur-Dindigul doubling at 159 km.
- PM Gati Shakti launched: 13 October 2021; integrates 44 Central Ministries and 36 states/UTs.
