Traditional rickshaws and E-Rickshaws are available which will take you to GT Road(from where you can catch bus towards Bally, Uttarpara), Don Bosco School(buses to Howrah can be availed from here) and even to Belurmath.
Rickshaws are available just outside the station. You need to use the PF 1 exit and they will be waiting for you. However, beware as their charges are quite variable and towards the higher side.
To avail e-rickshaws(totos), you need to turn right and cross the flyover. Once you do that, turn left and keep walking...
more... till you see the end of the flyover and there the e-rickshaw stand will be there.
Only way to catch any bus is to go to GT Road near MCKV Engineering College(15 mins walking distance). The best way is definitely the e-rickshaw(toto)
