ALD has been purposefully been blocked frm tatkal booking for many trains!!
I again repeat, for Reserved Tickets, it Station Combination Restriction, not Distance Restriction (which happen for GEN Ticket)!!
Mahanagri Exp, SL Tatkal is been restricted from ALD-LTT (People willing, get it booked from Vindhyachal)!!
There would be lot many trains, passing ALD, without ALD Tatkal Quota!!
