Tamil Nadu Budget Eyes Metro Rail Link with Karnataka's Bommasandra
The government of Tamil Nadu gave a big speech about its money plan, called a budget.
In the speech, it said it wants to build a new Metro train line.
The train line would connect two towns: Hosur in Tamil Nadu and Bommasandra in Karnataka.
These towns are near the big cities of Chennai and Bengaluru.
A Metro is a fast train that helps many people travel.
The government is already building a bigger Metro in Chennai with three new routes.
The first part of this new Metro will open very soon.
The government also wants to buy 1,000 new electric buses for Chennai.
Electric buses are good because they do not use petrol.
All these plans will help people travel more easily.
Tamil Nadu Finance Minister N Marie Wilson announced a proposal for a Metro rail link from Hosur to Karnataka's Bommasandra during the state Budget address.
Chennai Metro Rail Phase II spans 118.9 km across three corridors at an estimated completion cost of Rs 63,246 crore.
The first Phase II stretch, from Poonamallee Bypass to Porur Junction (14.64 km, 11 stations), is scheduled to be commissioned shortly.
Three proposed Metro lines — Chennai Airport-Kilambakkam, Koyambedu-Pattabiram (via Avadi) and Poonamallee-Sunguvarchathiram (via Sriperumbudur) — await Central government approval.
The state will procure 1,000 new air-conditioned electric buses for the Chennai Metropolitan Transport Corporation this financial year under the gross cost contract model.
