As per Gulbarga station sources the TTE who board at Solapur for Basava wont allot any seats till Gulbarga station this is unofficial arrangement to make people book forcefully from Hotgi and by that it also denies the revenue for Gulbarga for this train...
So do not worry the TTE will not issue tickets to RAC travellers and more over there are not much pax from Bijapur Bagalkot etc.. in tatkal for this train. Enjoy your train ... and spend more to travel in tatkal from Gulbarga and account goes to other station :-)
