On this very site, please enter station from as Howrah, select Kolkatta Howrah, and in the column below enter Digha, choose Digha Ghat or Digha, whichever one is convenient, and click on get trains.. That will show you all trains from HWH to Digha.. you can also click on the time of departure and it will re-arrange itself to show you in 24 hr format, i.e. 0020 means midnight of that day (remember world clock date is changed at 1200 p.m. meaning 0000 hrs), and then 0020 means next day... please be careful about this please! Good wishes.
