- Proposed Tumakuru Metro Extension:
- A crucial component of the DPR will be the preparation of an Alternative Analysis Report (AAR). This report is intended to evaluate all viable transport options, assess potential impacts, and capture stakeholder feedback. The objective is to identify the most suitable and locally preferred alternative, thereby establishing the necessity and relevance of the metro extension. What the DPR will cover According to BMRCL officials, the DPR must include a detailed assessment of the existing urban profile, land use patterns, and transport characteristics. “It will review earlier studies such as the Master Plan, Comprehensive Mobility Plan, and previous metro proposals. The consultant is required to analyse current and future travel demand using surveys and modelling techniques, and estimate ridership. Key tasks include selecting appropriate transit technology and finalising corridor alignment based on road geometry, geotechnical conditions, land acquisition needs, and utility mapping,” an official said. Proposed key stations
Amid a debate over its necessity, the Bangalore Metro Rail Corporation Ltd. (BMRCL) has initiated the process of preparing a Detailed Project Report (DPR) for extending metro rail services from Bengaluru to Tumakuru. The proposed corridor will begin at Madavara, the northern terminal of the existing Green Line, and is aimed at providing direct metro connectivity between the capital city and the neighbouring district.
As part of this process, BMRCL has awarded a contract for preparing the DPR to Aarvee Engineering Consultants. The consultancy will prepare the report for the proposed 59.60-km-long metro line at a cost not exceeding ₹1.2 crore. Tenders were floated in November 2025.
The Bengaluru–Tumakuru metro project will have 25 stations. As per earlier State Budget projections, the total cost of the project has been estimated at ₹20,649 crore, making it one of the most ambitious inter-district metro proposals in Karnataka.
Speaking to The Hindu, Yashwanth Chavan, chief public relations officer of BMRCL, said that the consultancy appointed for the project has commenced work on the Detailed Project Report, with a particular focus on field-level studies along the proposed corridor. “The ongoing exercise includes ground surveys, data collection on traffic and travel patterns, preliminary alignment checks, various assessments, and initial geotechnical investigations, all of which will form the basis for detailed planning and design of the proposed metro extension,” he added.
Feasibility report
The decision to move ahead with the DPR follows an announcement by Home Minister G. Parameshwara, who had stated that the State government had accepted a feasibility report BMRCL had submitted in May last year. The proposed corridor is part of Namma Metro’s Phase 4 expansion.
However, the proposal has sparked considerable discussion over whether a high-cost metro project is necessary, given that Tumakuru, located about 70 km from Bengaluru’s city centre, is already the focus of multiple connectivity initiatives. Railway Infrastructure Development Company Karnataka (K-RIDE) has proposed a suburban rail connection to Tumakuru, while South Western Railway is planning infrastructure upgrades to strengthen rail links between the two districts.
Proposed Tumakuru Metro Extension:
Route Length: 59.60 km
Total Stations: 26
From: Madavara
To: Nagannanapalya (Tumakuru)
What the DPR will cover
Makali
Dasanapura
Nelamangala
Nelamangala Tollgate
T. Begur
Thippagondanahalli
Sompura Industrial Area
Dobbspet
Hirehalli Industrial Area
Kyatsandra
Tumakuru Bus Stand
TUDA Layout
Nagannanapalya
Station planning will focus on layout design, accessibility, multimodal integration, non-motorised transport facilities, and platform capacity. An Intermodal Integration Plan is also mandated to ensure seamless physical, operational, fare, and institutional integration with existing transport systems.
“In addition, the DPR must comprehensively cover train operations, advanced signalling systems, preferably CBTC with GoA4 automation telecommunications, fare collection, rolling stock, power supply, traction, ventilation, depot planning, and safety measures. Environmental and social impact assessments, disaster management strategies, detailed cost estimates, financial modelling, funding options, and implementation timelines are also compulsory, along with stakeholder consultations at various stages of the project,” an official added.
