Dedicated Freight Corridors: Western Corridor Completed and New East-West Corridor Proposed
The lecture explains the completion of the Western Dedicated Freight Corridor, compares India’s Eastern and Western freight corridors, highlights Bihar’s Sonnagar terminal, and notes a new East-West corridor proposed in Union Budget 2026-27.
2,843 kmcombined length of Eastern + Western DFCs
1,506 kmWestern DFC
1,337 kmEastern DFC
2,052 kmproposed Dankuni-Surat East-West DFC
Current DFC network
Western Dedicated Freight Corridor: Dadri to Jawaharlal Nehru Port (JNPT), Maharashtra; length stated as 1,506 km.
Eastern Dedicated Freight Corridor: Sahnewal/Ludhiana to Sonnagar in Aurangabad district, Bihar; length stated as 1,337 km.
A Dedicated Freight Corridor is a railway corridor built primarily for freight trains, separating heavy goods traffic from regular passenger routes.
Implementing organisation: Dedicated Freight Corridor Corporation of India Limited (DFCCIL), under the Ministry of Railways.
Why dedicated freight tracks matter
Faster freight movement and higher network capacity.
Lower logistics cost and reduced congestion on passenger railway lines.
Western DFC supports double-stack container movement and stronger port connectivity.
Electric traction and efficient operations can reduce fuel use and emissions.
Separate freight tracks improve supply-chain reliability for minerals, industry and agriculture.
Three corridors to remember

Question 1: With reference to the Dedicated Freight Corridors in India, consider the following statements:

International Relations • Water Sharing • Bihar
India-Bangladesh Ganga Water Treaty: Bihar Raises Lean-Season Concerns
The 1996 Ganga Water Sharing Treaty at Farakka completes its 30-year period in 2026, reopening debate over renewal, lean-season water availability and Bihar’s demand that its upstream irrigation and water-security concerns receive greater consideration.
12 Dec 1996treaty signed
30 yearstreaty duration stated
1 Jan-31 Maylean season
1975Farakka Barrage commissioned
Treaty & Farakka basics
The treaty is a bilateral agreement between India and Bangladesh for sharing Ganga waters at Farakka during the lean season.
The lecture gives the lean season as 1 January to 31 May.
Farakka Barrage: Murshidabad district, West Bengal; commissioned in 1975.
Its feeder canal diverts part of the Ganga flow towards the Bhagirathi-Hooghly system to support navigation towards Kolkata Port; remaining flow continues towards the Padma in Bangladesh.
Bihar is not a direct treaty signatory.
Why Bihar is concerned
The lecture links dry-season releases with lean-season water stress affecting irrigation and local water availability upstream in Bihar.
Bihar argues that tributaries flowing through the State contribute substantially to the Ganga system and that its agricultural and drinking-water needs should be considered.
The discussion also connects Farakka with siltation, flood and erosion concerns affecting Bihar.
With the treaty period ending in 2026, Bihar wants its interests reflected in any future renewal arrangement.
The lecture specifically mentions a demand to reconsider the stated 1,500-cusec lean-period obligation.

Question 2: With reference to the 1996 Ganga Water Sharing Treaty at Farakka, consider the following statements:

Bihar • Railway Policing • Internal Security
Bihar Railway Police Reorganisation: New Subdivisions at Rajgir and Sasaram
The proposed reorganisation expands Bihar’s state railway-police structure with new subdivisions, circles and police stations to improve passenger security, supervision and response time across a growing rail network.
4railway police districts in Bihar
12 → 14subdivisions after proposal
17 → 21railway circles
68 → 71railway police stations
Proposed new units
New railway police subdivisions: Rajgir and Sasaram, under the Patna railway police district.
New railway circles: Rajgir, Thawe, Khagaria and Purnia.
New railway police stations: Hilsa, Rajendra Nagar Terminal and Kursela.
The four railway police districts named in the lecture are Patna, Muzaffarpur, Jamalpur and Katihar.
Structure & significance
Hierarchy explained in the lecture: Railway Police District → Subdivision → Circle → Police Station.
More units can mean better supervision, greater police presence and quicker response at stations and trains.
The reorganisation is linked with Bihar’s high train movement and growing passenger, premium-train and freight traffic.
This is a state railway police reorganisation proposal; it should not be confused with expansion of the Railway Protection Force under the Ministry of Railways.
Question 3: With reference to the proposed reorganisation of railway police units in Bihar, consider the following statements:

Bihar • Food Processing • UAE Investment
Bihar-UAE Food Processing Initiative: Integrated Agri-Food Cluster for Gulf Markets
Bihar’s Industries Department has signed an MoU with M Global Foundation for a UAE-backed integrated agri-food and food-processing cluster aimed at attracting Gulf investment and linking Bihar’s farm sector with global supply chains.
What is being proposed?
MoU parties highlighted: Bihar Industries Department and M Global Foundation.
The initiative seeks UAE and wider Gulf-region investment in Bihar’s food-processing sector.
The proposed integrated cluster would combine farmers, processors, storage, logistics, marketing and export infrastructure.
The objective is to connect Bihar’s agricultural production with domestic and international markets, including Gulf food-supply chains.
Why Bihar has potential
Products mentioned include makhana, Muzaffarpur litchi, banana, vegetables, milk and maize.
Value addition can increase farm income and strengthen the State economy beyond raw-produce sales.
The UAE is described as a gateway to Gulf markets, which depend heavily on imported food.
Investment can strengthen processing technology, cold/storage infrastructure, logistics, branding and export readiness.
Question 4: With reference to the Bihar-UAE food processing cluster initiative, consider the following statements:

Bihar • Climate-Resilient Agriculture • World Bank
Bihar Water Security and Irrigation Modernisation Project: Climate-Resilient Farming Push
Bihar plans a major World Bank-assisted programme combining irrigation modernisation, flood-risk reduction, water governance and climate-resilient agriculture across selected command-area blocks.
₹4,415 crproject cost stated in the lecture
70%World Bank contribution stated
30%Bihar government share stated
11 blocksselected command-area coverage
Why Bihar needs climate resilience
The lecture describes Bihar’s flood-drought paradox: flood vulnerability in much of north Bihar and drought risk in parts of south Bihar.
Erratic monsoon behaviour and climate change increase agricultural risk.
Older irrigation systems require modernisation, while small and marginal farmers need more resilient production systems.
Examples of climate-resilient practices mentioned: laser land levelling, direct-seeded rice, alternate wetting and drying, crop diversification, zero tillage and water-efficient irrigation.
Four project components
1. Irrigation modernisation: rehabilitation of irrigation systems, on-farm development and climate-resilient agriculture.
2. Flood-risk reduction: stronger embankments, river-bank protection and green infrastructure.
3. Water governance: capacity building, a Bihar water policy and a proposed water regulatory authority.
4. Project management: implementation, monitoring, evaluation and financial management.
Command-area coverage described in the lecture

Science & Technology • Fisheries • ICAR
Matsya Maitri App: Contactless Fish Measurement for Fisheries Research
The Matsya Maitri application developed by ICAR-Central Marine Fisheries Research Institute uses smartphone imaging to measure fish length and width without physically handling specimens and automatically produces research-ready length-frequency data.

Length + Widthcontactless measurement
CSVdataset export mentioned
How the app works
A fish specimen/sample is photographed using a smartphone camera through the app.
The app measures length and width without physically handling the fish.
Measurements are recorded automatically and the photograph is saved with the sampling session.
The lecture says the output can be exported as a CSV dataset and used to generate length-frequency information.
Why the data is useful
Helps researchers understand fish growth patterns.
Supports analysis of population structure by comparing different size groups.
Changes in size composition can help estimate fishing pressure and stock health.
The resulting datasets support sustainable fisheries assessment and management.
