Construction Technology
- Elevated viaduct consisting of pre-stressed concrete “Box” shaped Grinders on the single pier with pile/open foundations. It requires very less space occupancy on road as no ground support is required for the construction of above piers.
- The Metro Stations are constructed with state of the art precast pre-stressed concrete technology on a single row of pier on the road median which not only reduces the road occupancy during construction but also improved the speed & quality of construction.
- Underground tunnelling by TBM (Tunnel Boring machine) using EPBM (Earth Pressure Balancing Method) technology & also some portion by NATM (North Austrian tunnelling method) and UG station by the cut & cover with TOP-DOWN methodology

Signalling & Train Control
‘CATC’ (Continuous Automatic Train Control System) based on “CBTC” (Communication based Train Control System) which includes ATP (Automatic Train Protection), ATO (Automatic Train Operation) and ATS (Automatic Train Supervision) subsystems using radio communication between Trackside and Train. Train operations planned to be Driverless.
Telecommunication and Fare Collection
- Integrated System with Fibre Optic cable, SCADA, Train Radio, PA system etc
- Train information system, Control telephones, and Centralized Clock System.
- Automatic Fare collection system with POM and Smart card etc.
Technology in Operations
- Signalling system is equipped with CBTC system, which is capable to operate the trains at frequency of 90 seconds.
- Rolling Stock & Signalling system are equipped with GoA level-3, which is capable of Driverless Train Operations. Rolling Stock is equipped with regenerative braking, which regenerates 13-14% of the energy consumed in operations of rolling stock.
- Fare Collection System is functioning on Open Loop Payment System to promote digitized payment system.
- As an initiative towards sustainable energy, Solar Power generation system has been installed.
- CCTV Cameras installed in Ahmedabad Metro are equipped with Video Analytics function.
- Developed & Implemented in-house Data Integration System for reporting of Revenue Data
