There are many reasons why Orissa SK should not stop at Purulia:
(1) Orissa SK conceptually should have minimal stops outside Orissa. Outside the home state, SKs have commercial stops at stations to meet operational requirements and on rare occassions at very large stations/junctions.
(2) Train already stops at Tatanagar(only 89 kms from Purulia) and Gomoh (only 92 kms from Purulia)
(3) Orissa SK...

(4) Purulia is not a large station where a large number of paxs are expected to aboard this train. (In fact did not classify as A grade stationin 2014-15 i.e. revenue less than 8 Crore Rs/Annum)
(5) There are already many better options from Purulia to Delhi and a few well timed connections towards BBS/Puri.
