I have to travel by 12325 Kolkata Nangal Dam express next month. I would be reaching Howrah by Chennai Howrah mail and hence need to go to Kolkata to board the next train. I know taking a cab would be the easiest option. But, since I have sufficient time in hand and would also like to explore the city, can someone suggest me bus route from Howrah to Kolkata? From the maps I could understand that If one reaches Belgachia, then it would be easy to walk to the station. Please help me and suggest me bus routes from HWH to Kolkata.
