शिव की जटाओं से बहती है शिव गंगा - Divyanshu

I have planned to go to Shimla from Chennai. So planned to go thru New Delhi. Now i planned to stay in New Delhi for two days then leaving to Shimla. Is it possible to book through ticket(connection ticket) from Chennai to Shimla? If so wat will be the diffence in fares of booking thru ticket and separate tickets for 3AC? Please help me out on this.
