This is beauty of IR, they will always choose outskirt stations to de-congest main station. Yard is not only the problem in pune, compared to any big metros, Pune has just 6 pf's. Here is the big problem, they want reduce both passing by and originating trains at main station. I don't think all people live near by to pune station, how they travel to the main station in similar way they to travel for HDP/KK/CCH
