Tell me about the infrastructure in Tamil Nadu. 
 Sure! Tamil Nadu has a well-developed rail network as part of Southern Railway. 
 Is that the only mode of transport? 
 No, there is also road transport. Road transport is provided by state-owned Tamil Nadu State Transport Corporation. 
 Does the state also own air transport? 
 Yes, the state has civilian airports along with its four air bases of the Indian Air Force. 
 What about their language, do they all speak the same dialect? 
 A 2001 census showed the top first language spoken is Tamil at 90%, followed by Telugu, Kannada, Urdu, Malayalam, Marathi, and Saurashtra. 
 Wow! do you know where Tamil originates from? 
 Unfortunately I don't know that. However, it was the first language to be recognized as a classical language of India. 
 Do they teach Tamil in schools? 
 I'm not sure about that. An interesting fact, though, is that Tamil was the first Indian language to be printed and published, after the Portuguese published a Tamil book in 1578. 
 Thank you for all the information. 
 You're very welcome!
