The 70 mile(112km) long 'Gang Canal' in the Ganganagar District was built as part of the '[[Sutlej Valley Project Railways|Sutlej Valley Project]]' between 1924 and 1928.The canal was lined with concrete and a number of tramways were used during its construction. The kankar [[Kankar]] for the concrete was obtained from the quarries at Darbari <ref name = DarvRJ10>“Industrial Railways and Locomotives of India and South Asia” compiled by Simon Darvill.

There were 9 miles(14km) of 2ft/610mm narrow gauge([[Rail_gauge#Narrow_Gauge|NG]]) hand worked tramway at the quarries used to transfer the kankar to the mainline loading site located on the [[Bikaner State Railway]] (BkSR) mainline Lalgarh Junction to Kolayat section. At the loading site the kankar [[Kankar|Kankar limestone]] was discharged by gravity into special MG wagons <ref name = DarvRJ10/>

After the kankar [[Kankar]] was unloaded at Khai it was taken to the screening plant by a 2ft/610mm narrow gauge([[Rail_gauge#Narrow_Gauge|NG]]) tramway. The total of 5 miles(8km) of track linked the screening plant, lime kilns, sand and ballast storage and the concrete plant, all hand worked. A further 2ft/610mm [[Rail_gauge#Narrow_Gauge|NG]] tramway ran from the cement plant to the ‘Gang Canal’ works Khai <ref name = DarvRJ10/>.
