there used to be a passenger train on that route. My mom was born and bought up in dandeli and she mentioned that to me on how she and her brother used to sit and study on Pf at night, and how they used to have a railway connection to Mumbai (not sure of this) back then. That route is currently only used by paper mills now, and once in a while you can hear the hoot of an alco as it approaches the mill. :)
