Pune is set to become one of the select Indian cities to operate a third-rail electrification system as Pune Metro Line 3 moves closer to commercial operations.
The 23-km Hinjawadi–Shivajinagar corridor will be the first metro line in the city to deploy a third-rail electrification system, introducing a globally preferred 750-volt DC power supply technology designed for high-frequency urban transit operations.
The third-rail electrification system already powers some of India’s prominent metro networks, including sections of the Kolkata Metro, Bengaluru’s Namma Metro and several newer urban transit systems.
The technology has gained widespread adoption due to its compact design, operational efficiency and reduced visual impact.
With Pune Metro Line 3, the city will now join this growing league of metro systems embracing next-generation transport infrastructure.
Unlike conventional electrification systems that depend on overhead wires and supporting masts, the third-rail electrification system delivers power through an additional conductor rail installed alongside the running tracks.
Electricity is collected by shoes mounted beneath metro trains, eliminating the need for overhead equipment while creating a cleaner and more aesthetically pleasing urban skyline.

Benefits of the third-rail electrification system
The third-rail electrification system offers several operational and commuter advantages, including:
- High reliability with reduced susceptibility to power failures and service disruptions.
- Minimal visual clutter due to the absence of overhead wires and masts.
- Lower maintenance requirements compared to conventional overhead electrification systems.
- Greater suitability for high-frequency urban transit operations in densely populated metropolitan areas.
- Potential benefits for commuters through shorter waiting times, reliable schedules and smoother journeys.
For Pune Metro Line 3, the third-rail electrification system assumes additional significance as the corridor connects Hinjawadi’s Rajiv Gandhi Infotech Park with major urban centres such as Wakad, Baner, Balewadi, University Circle and Shivajinagar.
The absence of overhead wiring across one of Pune’s busiest growth corridors is expected to contribute to a more streamlined and aesthetically integrated transport infrastructure.
CBTC to Complement third-rail electrification system
Complementing the third-rail electrification system is Communications-Based Train Control (CBTC), an advanced digital signalling technology that continuously exchanges information between trains and trackside equipment.
Unlike conventional signalling methods based on fixed blocks, CBTC determines the precise location, speed and movement of every train in real time.
This enables metro services to operate at shorter intervals while maintaining the highest safety standards.
The combination of the third-rail electrification system and CBTC will enable Metro Line 3 to support high-frequency operations, increased passenger capacity and dependable service levels as commuter demand between Pune’s IT hub and the city centre continues to grow.
The technology platform is also designed to accommodate future operational upgrades, including higher levels of automation.
Pune Metro Line 3 Completes End-to-End Trial Runs
Pune Metro Line 3, also known as the Puneri Metro, has successfully completed end-to-end trial runs across its entire 23-km fully elevated corridor, marking a significant milestone towards the commencement of commercial operations.
The Hinjawadi–Shivajinagar corridor has now entered its final phase of readiness, subject to statutory approvals and regulatory clearances. The metro line will be commissioned in phases.
During the first phase, the 13.3-km section between Maan and R. K. Laxman Museum, comprising 12 stations, will become operational. In the subsequent phase, the corridor will be extended to District Court, enabling integration with the Maha Metro network.
Once fully operational, the third-rail electrification system powering Pune Metro Line 3 is expected to significantly improve urban mobility by reducing travel time between Shivajinagar and Hinjawadi to around 45 minutes from the current 1.5 hours.
The corridor is projected to cut commute duration by more than 50 per cent while supporting faster, more reliable and efficient public transportation for the city.
