This one is better known:
It was in Bihar and is now in Jharkhand. It is on the way from Chandil to Muri. A number of express trains pass this way, but only two pairs of passenger trains stop here-one between Tatanagar and Hatia and another between Tatanagar and Barkakana.
This one in Karnataka is nominally a junction, but has fallen on bad days:
You can see the branching of lines in these pictures. This station is on a branch running south from Hosapete (formerly Hospet). At this junction (which must qualify as one of the smallest and most rudimentary stations with the title of junction) short lines ran to Kotturu and Swamihalli. There used to be heavy iron ore traffic on the then metre gauge line from Swamihalli.
In due course these lines were converted to broad gauge. From Kotturu a new BG line was extended to Harihar, near Hubli on the Pune-Bengaluru route. It was then discovered that the slopes on the BG line between Gunda Road and Kotturu were too steep for safe running, so no train runs there. The line from Kotturu to Harihar has one pair of trains a day. Goods trains appear to run from Hosapete to Swamihalli though there seems to be a bypass around Gunda Road. No passenger service runs on this line.
Then there are place names such as Ramagundam.
I don’t know about the etymology of the place in Jharkhand, but “Gundam” is a body of water in languages such as Kannada andTelugu. This would not have anything to do with the Japanese animes of the same name. And Karnataka had a CM called Gundu Rao.
