**Executive Summary**
The Ministry of Railways approved two infrastructure projects on March 24, 2026, totaling ₹647.58 crore to enhance connectivity and operational efficiency in Gujarat and Bihar. The sanctioned works include a Rail-over-Rail (RoR) flyover at Kosamba and a new rail bypass at Bhagalpur. These projects aim to eliminate congestion and facilitate safer, uninterrupted train movement on critical Western and Eastern Railway routes.
**Key Points / Main Content**
**Kosamba Rail-over-Rail (RoR) Flyover (Western Railway)**
* **Project Scope:** Construction of a 9.20 km RoR flyover for the Kosamba–Umrapada Gauge Conversion (GC) section.
* **Financials:** The estimated completion cost is sanctioned at ₹344.38 crore.
* **Operational Necessity:** Direct surface crossing between the GC line and the Mumbai–Vadodara main line is unfeasible due to the Dedicated Freight Corridor alignment.
* **Primary Benefit:** The flyover will eliminate surface crossings, allowing seamless integration of the GC section with the main line and ensuring safe train movement.
**Bhagalpur Bypass (Eastern Railway)**
* **Project Scope:** Development of a 13.38 km bypass connecting Gonudham Halt (Barahat-Bhagalpur section) with Sabour (Bhagalpur-Sahibganj section).
* **Financials:** The project is approved at an estimated cost of ₹303.20 crore.
* **Congestion Relief:** Addresses current over-utilization (125% capacity) of the Barahat–Bhagalpur section.
* **Efficiency Gains:** Eliminates the requirement for engine reversals at Bhagalpur junction, reducing detention times and improving train punctuality.
**Strategic Objectives**
* **Network Decongestion:** Prioritizes capacity augmentation to meet rising demands for passenger and freight transportation.
* **Safety and Fluidity:** Enhances overall operational safety and fluidity across critical rail corridors in Gujarat and Bihar.
**Impact Analysis**
**Western Railway**
**Impact**
The approval enables the completion of the Kosamba–Umrapada gauge conversion benefits by resolving connectivity issues caused by the Dedicated Freight Corridor.
**Action Required**
Commence construction of the 9.20 km RoR flyover within the sanctioned budget of ₹344.38 crore to integrate the section with the Mumbai–Vadodara main line.
**Eastern Railway**
**Impact**
The bypass will significantly reduce the operational burden on Bhagalpur junction and improve the flow of traffic between Barahat and Sahibganj.
**Action Required**
Execute the construction of the 13.38 km bypass connecting Gonudham Halt and Sabour to eliminate engine reversal inefficiencies.
**Passenger and Freight Stakeholders**
**Impact**
Users will experience improved punctuality, enhanced safety, and increased capacity for both passenger travel and goods transport.
**Action Required**
No direct action is required from these stakeholders; they will benefit from the improved infrastructure upon project completion.

Projects Worth ₹647.58 Crore to Ensure Uninterrupted and

The Ministry of Railways has approved two important rail infrastructure projects in Western Railway and
Eastern Railway aimed at enhancing connectivity, easing congestion and improving operational
efficiency. The projects include construction of a Rail Over Rail (RoR) flyover at Kosamba for
connectivity to the Kosamba–Umrapada Gauge Conversion section in Gujarat and development of a new
rail bypass at Bhagalpur in Bihar. The total sanctioned cost of the two projects is ₹647.58 crore.
Sanction of Rail-over-Rail Flyover at Kosamba – Umrapada GC Section (9.20 km), Western
Railway
Indian Railways has approved the construction of a Rail-over-Rail (RoR) Flyover to provide seamless
connectivity to the Kosamba – Umrapada Gauge Conversion (GC) section (9.20 km) at a total estimated
completion cost of ₹344.38 crore. The Kosamba–Umrapada section lies on the eastern side of the
Mumbai–Vadodara main line and its gauge conversion is currently underway.
Due to the presence of the Dedicated Freight Corridor alignment, direct connectivity of the gauge
converted line with the main line is not feasible through a surface crossing. The approved Rail Over Rail
flyover will eliminate surface crossings and enable seamless integration of the Gauge Conversion section
with the Mumbai–Vadodara main line. This will ensure uninterrupted and safe movement of trains on
these critical routes and help fully realize the benefits of the gauge conversion project.
Sanction of Bhagalpur Bypass (13.38 km), Eastern Railway
The Ministry has also approved the construction of the Bhagalpur Bypass (13.38 km) in Eastern Railway
at an estimated cost of ₹303.20 crore. The bypass will connect Gonudham Halt on the Barahat-Bhagalpur
section with Sabour on the Bhagalpur-Sahibganj section, thereby easing congestion at Bhagalpur junction.
At present, the Barahat–Bhagalpur section is operating at more than 125 percent capacity utilisation,
leading to severe congestion. Trains moving between the Barahat–Bhagalpur and Bhagalpur–Sahibganj
sections require engine reversal at Bhagalpur, resulting in detention and operational inefficiencies. The
approved bypass will significantly improve operational fluidity and punctuality.These infrastructure works will strengthen rail connectivity in Gujarat and Bihar, enhance safety, reduce
congestion, and improve overall efficiency of train operations. The Ministry of Railways continues to
prioritise capacity augmentation and network decongestion to meet the growing passenger and freight
transportation demands of the country.
