It is only for Bongaon section. I suggest to divert some Bongaon & Barasat Local towards Prinsepghat & Kolkata station. Bongaon Local should also start from Kolkata terminal & should use platform no. 5. As a result platform no 3 & 4 will be released for other trains like Main section & dankuni section. Express train can also move smoothly on Line no 4 & 3 form DDJ to Sealdah. I also suggest to make new rail lines from Kankurgachi to Sealdah Platform no 9A & 9B. Some old rail track also exist where lalgola Pass, Uttarbanga , Asansol Intercity stands for carshed
