Okhamandal State Railway
The Okhamandal State Railway was a 37 mile(59km) metre gauge(MG) line financed by the Princely Okhamandal State. The line between Kuranga and Arthara +((see note) was sanctioned in 1913. It was reported that as at 1918 "work on this line has been stopped for the present" due to the war.  .
The actual date of opening of this line has not been found – it must be between 1919 and 1921
+ Spelling Note:
- Kuranga via Dwarka to Okha is about 38 miles. So Arthara must be close to Okha.
- Adatra is used in 1943 as the terminal of the 37 mile railway from Kuranga . It is possible Arthara and Adatra are the same place
1921: the Gaekwar's Baroda State Railway(GBSR) took over the management and operation of the ‘Okhamandal State Railway’.
1931: The 1931 Map  shows the JDR as working the line from Jamnagar via Kuranga and to Okha Port.
