See, SDAH is the station with most no. of footfalls in India, with multiple EMU routes. Shantipur, Kalyani Simanta, Gede, Krishnanagar/Lalgola, Bongaon, Hasnabad, Dankuni, Diamond Harbour, Canning, Budge Budge, Namkhana, with circular railway. All EMU's terminate or originate here. So, the EMU count comes to 337+337, plus expresses. All these are facts, not my assumptions.
