With a stretch of 299.55 kilometres (186.13 mi), this corridor passes through the Aravalli Ranges of North Gujarat and the Udaipur division of Rajasthan, where there are zinc and phosphate mines in Zawar and Umra, making it a direct and important mineral transportation route to the rest of India.

This mainline route is divided into two sections: It also contains two branch lines of this corridor; both come in the Western Railways zone.

[7] In 1961, it was converted to broad gauge and in the same year the survey and construction of Kapadvanj–Modasa section, an extension of the branch line, was started with a planned length of 89 kilometres (55 mi).

[8] It was halted for two decades, with construction only revived in 2000; it became operational on 28 October 2001, with a total length of 138 kilometres (86 mi) and direct connections to Nadiad.

[13] In this joint project, the first section of the mainline from the Western Railways zone side was fully converted into broad gauge; DEMU (diesel-electrical multiple unit) trains started running on the route from 15 October 2019.
