No. Never. I was a resident of BGM and used to travel to Dandeli by Road and not trains. And as per my know-how, Dandeli has a rail route from LWR - perhaps to facilitate the West Coast Paper Mills. However, I remember seeing a track close to the paper mills. Not sure if any passenger train did ever make any journey to and from Dandeli. Now that my relative has retired from the services from the paper mills and settled in BGM, we seldom visit Dandeli now. :)
