distance restriction rexalaxed between solapur to ahmednagar and gulbarga to kopergaon. I dont know exactaly in intermidate stations are also served. if they are you can buy unreserved tickets. if you you cannot buy from kurudawadi also so there is no point in getting down there. reserved ticket can be booked between DD-KPG which may be indicative that unserved tickets are also issued but i am not 100% sure
