The Gondal-Porbandar Railway was formed in 1911 as the nucleus of a new metre gauge(MG) system, with the Gondal State Railway(GSR) working jointly with the Porbandar State Railway(PSR) thus forming the Gondal-Porbandar Railway.The first section opened in 1913 and completed to Dhari in 1915, a length of 37 miles(52km). The line was initially worked by the Bhavnagar-Gondal-Junagad-Porbandar Railway(BGJPR). 
In 1919, GSR took over the sole working of the PSR and the name reverted to the Gondal State Railway(GSR)
In 1948, GSR became a part of Saurashtra Railway.
