Hi, I am travelling from Mysore to Chennai in Shatabdi express. I booked Tatkal ticket from Mysore (boarding point Mysore) to Chennai, but I will not be able to board from Mysore. Instead I will have to board from Bangalore. Just wanted to know if this is valid. Also, this train stops only in Bangalore between Mysore and Chennai. What happens if I do? Want to understand exact rules of the same. Thanks.
