DPR work starts for proposed Bengaluru–Tumakuru metro line

Amid a statement implicit its necessity, the Bangalore Metro Rail Corporation Ltd. (BMRCL) has initiated the process of preparing a Detailed Project Report (DPR) for extending metro obstruction services from Bengaluru to Tumakuru. The projected corridor volition statesman astatine Madavara, the bluish terminal of the existing Green Line, and is aimed astatine providing nonstop metro connectivity betwixt the superior metropolis and the neighbouring district.

As portion of this process, BMRCL has awarded a declaration for preparing the DPR to Aarvee Engineering Consultants. The consultancy volition hole the study for the projected 59.60-km-long metro enactment astatine a outgo not exceeding ₹1.2 crore. Tenders were floated successful November 2025.

The Bengaluru–Tumakuru metro task volition person 25 stations. As per earlier State Budget projections, the full outgo of the task has been estimated astatine ₹20,649 crore, making it 1 of the astir ambitious inter-district metro proposals successful Karnataka.

Speaking to The Hindu, Yashwanth Chavan, main nationalist relations serviceman of BMRCL, said that the consultancy appointed for the task has commenced enactment connected the Detailed Project Report, with a peculiar absorption connected field-level studies on the projected corridor. “The ongoing workout includes crushed surveys, information postulation connected postulation and question patterns, preliminary alignment checks, assorted assessments, and archetypal geotechnical investigations, each of which volition signifier the ground for elaborate readying and plan of the projected metro extension,” helium added.

Feasibility study

The determination to determination up with the DPR follows an announcement by Home Minister G. Parameshwara, who had stated that the State authorities had accepted a feasibility study BMRCL had submitted successful May past year. The projected corridor is portion of Namma Metro’s Phase 4 expansion.

However, the connection has sparked sizeable treatment implicit whether a high-cost metro task is necessary, fixed that Tumakuru, located astir 70 km from Bengaluru’s metropolis centre, is already the absorption of aggregate connectivity initiatives. Railway Infrastructure Development Company Karnataka (K-RIDE) has projected a suburban obstruction transportation to Tumakuru, portion South Western Railway is readying infrastructure upgrades to fortify obstruction links betwixt the 2 districts.

A important constituent of the DPR volition beryllium the mentation of an Alternative Analysis Report (AAR). This study is intended to measure each viable transport options, measure imaginable impacts, and seizure stakeholder feedback. The nonsubjective is to place the astir suitable and locally preferred alternative, thereby establishing the necessity and relevance of the metro extension.

What the DPR volition cover

According to BMRCL officials, the DPR indispensable see a elaborate appraisal of the existing municipality profile, onshore usage patterns, and transport characteristics. “It volition reappraisal earlier studies specified arsenic the Master Plan, Comprehensive Mobility Plan, and erstwhile metro proposals. The advisor is required to analyse existent and aboriginal question request utilizing surveys and modelling techniques, and estimation ridership. Key tasks see selecting due transit exertion and finalising corridor alignment based connected roadworthy geometry, geotechnical conditions, onshore acquisition needs, and inferior mapping,” an authoritative said.

Station readying volition absorption connected layout design, accessibility, multimodal integration, non-motorised transport facilities, and level capacity. An Intermodal Integration Plan is besides mandated to guarantee seamless physical, operational, fare, and organization integration with existing transport systems.

“In addition, the DPR indispensable comprehensively screen bid operations, precocious signalling systems, preferably CBTC with GoA4 automation telecommunications, fare collection, rolling stock, powerfulness supply, traction, ventilation, depot planning, and information measures. Environmental and societal interaction assessments, catastrophe absorption strategies, elaborate outgo estimates, fiscal modelling, backing options, and implementation timelines are besides compulsory, on with stakeholder consultations astatine assorted stages of the project,” an authoritative added.
