At present there is no connectivity of digha ghat with ppta- phlg rail line but it's hardly a matter of laying just 1km track to connect this route & if it connects the ppta- phlg in Y fashion, it will be very fruitful for railway as well as for passengers. One side it will provide direct connectivity to patna junction in a very less time (trains coming from north bihar & up- east)in comparison to phulwarisharif main line and on the other side it will save phulwarisharif main line to get overload. One another important thing if something goes wrong on dnr-pwsf-pnbe section, it will provide an alternate route to connect patna jn.
