If you are planning for a sudden trip to Malda from Kolkata and you find that all trains have WL in the route then go for the Tatkal these two trains - Radhikapur exp (except weekend) and Jogbani exp. The demand of Tatkal is a bit less in these trains when compared to other trains of the route. If you are planning some 8-10 days prior to your journey, then you can easily get a RAC ticket also in Jogbani exp which will later get confirmed. Prefer Jogbani exp over Radhikapur exp because of better arrival time at Malda.
