Indian Railways Plans Four-Laning of 11,000 km High-Density Network

# Indian Railways Plans Four-Laning of 11,000 km High-Density Network ### Why in News? Indian Railways announced plans to add tracks on about **11,000 km** of its busiest corridors to increase capacity and reduce congestion. ### Why are these routes being expanded? - The seven high-density corridors make up a relatively small share of the rail network but carry a disproportionately large share of traffic. - Adding additional tracks can separate and increase passenger and freight capacity, reducing bottlenecks on routes such as Delhi–Howrah and Delhi–Mumbai. - The expansion is being paired with deployment of Kavach, India's indigenous **Automatic Train Protection** system. ### Exam Connect - **Kavach** → indigenous **Automatic Train Protection** system - **Kavach** → developed by **RDSO** - **High-density corridors** → major passenger and freight routes
