Bengaluru's Double-Decker Rail Alignment Boosts Connectivity

14 Aug 2023 CW Team

Bengaluru's Suburban rail project introduces a unique double-decker rail alignment for Corridor one and four at Yelahanka, showcasing an innovative approach to connectivity challenges. This method eliminates level crossings by elevating the rail formation, departing from traditional roads under bridges. The new alignment tackles waterlogging issues and reduces land acquisition needs.

The approach integrates effectively with the Bengaluru Metro at Benniganahalli, leading to cost savings and minimal demolitions. Minister MB Patil reveals that Corridor two, from Chikkabanavara to Baiyappanahalli, aims for completion within 26 months. The project is currently 10-15% complete, with groundwork involving land acquisition from South Western Railways and private and government properties.

Around 12 stations are planned under Corridor two, with 10 train rakes targeted for completion by 2025. Minister Patil also outlines plans for Corridor three and the Whitefield-Kengeri stretch under Corridor four. An ambitious proposal extends the suburban network to various locations, potentially expanding its reach to 452 km.

The project is budgeted at $157.67 bn, with $10 bn allocated for the current fiscal year and plans to secure $74.38 bn from the KFW European Bank. Corridor two's groundwork, surveying, utility identification, and geotechnical investigation are complete, with the project advancing to ground levelling and facility establishment. An eight-kilometre priority stretch from Chikkabanavara to Yeshwanthpur symbolises the project's momentum in reshaping Bengaluru's rail connectivity landscape.
