Some of the reason why it cannot be and shouldnot be extended to Kolkata
.
тАвBeing a train travelling more than 2000km, it will always require Secondary maintainance at it's destination which needs atleast 5hrs. Extending to Hwh will not provide the required TAT, provided it always runs late, extension to jwh can just worsen the things
тАвIf u check the seat avl of...
more... this train, u will see that it is in WL till nov, both the gen quota and pooled quota. But large no of seats are still vacant in trains between Kolkata and Gujarat like Shm bhuj exp, garbha exp, etc. A possible explaination of this can be the presence of many trains between kolkata and Ahmedabad or beyond but for places like Asn, Dhn, pnme, kqr, Gaya, this is only the single dedicated train.
тАвAnother prime function of this train is to connect two holy places of Jains, Parasnath and Palitana (close to Bhavnagar). So extending this train will divert it from it's original function
