yes but karmbhoomi express as per budget announcment should be an unreserved train but this train is reserved. but it runs as per the schedule of karmabhoomi express given in TAAG . SO this is surely Karmabhoomi express running as special but karmabhoomi was started 2 month before from LTT as unreserved train. May be they have added reserved class for festival season.
