Mr. Nargundkar was desperately trying to book a ticket back home to Belgaum from Mumbai for Diwali in November, but he was shocked to note that Chalukya Express the only direct train connecting Belgaum to Mumbai was not visible for reservations from November 1, 2012.
This is true, Chalukya express most probably from November 4, 2012 would commence its new route to Tirunelveli and Puducherry three days each.
Due to the change in route the train will be getting a new number and hence the same has not yet been updated on the website of the railways and hence one cannot book any tickets.
As per the http://indiarailinfo.com site the new train number of Puducherry Dadar Express could be 11006 and Tirunelveli Dadar Express could be 11022.
As one can do the reservation 120 days in advance actually the new numbers should have been visible in the booking charts 120 days in advance, but thanks to IT savyness of the railways, commuters are having a hard time getting their booking done.
