Jrc Is undergoing complete modification. So maybe they thought Giving halt at JRC will Provide more prominence. juc Has not seen any developmental works since years now. Also, it was supposed to cater pgw pax as well but the bjp mla spoiled it all. Otherwise, no logical reason
It is also possible that once the station is fully ready, they can shift 2-3 premium trains from Juc to JRC because they intend to have one major station
