Yeh dil maange more (RailFans, while ending their trip) - Kirti Solanki

Slightly keeping the conflicts between RFans a little aside, I want to know in general, like OUT OF NOWHERE, where did they get this idea of launching a DD for Keralites???? I mean it's the wrong thing I'm doing to barge in RFan's conflicts, but I want to understand this.... DD which was last launched 6 years back (TPTY VSKP DD), what made them think of launching another one??? What benefit r they planning to get for the Keralites???
