Becoz of close proximity of DGR to ASN which is the HQ of the div to which DGR belongs, DGR has neglible chances of getting a originating train. If some train is even introduced from DGR due to some political influence, it will surely get a extension to kolkata on one side or ASN on the other in the nxt 1 or 2 years just like the KOAA JSME PASS which was earlier started between KOAA and CRJ. U can only expect some MEMUs plying from DGR.
