*The [[Dholpur-Bari Light Railway]](DBLR) 2ft 6in/762mm narrow gauge([[Rail_gauge#Narrow_Gauge|NG]]) line had opened in 1908 as the 'Bari-Dholpur Tramway' to carry red sandstone from the Bari Quarry to [[Dholpur]] to connect with the ‘Indian Midland Section’ of the [[Great Indian Peninsula Railway]] (GIPR) <ref>[http://dsal.uchicago.edu/reference/gazetteer/pager.html?objectid=DS405.1.I34_V11_333.gif "Imperial Gazetteer of India", v. 11, p. 327; 1908]; Retrieved 23 Aug 2016</ref>.

*The [[Mohari-Karauli Railway]] was constructed by the [[Imperial Delhi Committee]] for the carriage of stone for New Delhi from Karauli (in some records Barauli) to Mohari Junction The 2ft 6in/762mm narrow gauge([[Rail_gauge#Narrow_Gauge|NG]]) line opened in 1917 and was taken over by the [[Princely states|Princely ]][[Dholpur State]] Durbar for the carriage of passengers and goods <ref>[https://archive.org/stream/BombayBarodaAndCentralIndiaRailwaySystem/Bombay_Baroda_And_Central_India_Railway_System#page/n233/mode/2up "Administration Report on the Railways in India – corrected up to 31st March 1918"; Superintendent of Government Printing, Calcutta; page 225, pdf233]; Retrieved 9 Feb 2016</ref>. The line was managed, maintained and worked by the Dholpur Durbar in conjunction with [[Dholpur-Bari Light Railway]](DBLR).

*In addition to the Bari Quarry mentioned above, two other quarries at Bansipaharpur and Birja were operational in 1922-23; both these quarries had sidings but the route of the lines has not been determined.

*At [[Dholpur]] there would have been a transhipment yard where the stone was transferred from the NG railway stated above to the broad gauge([[Rail_gauge#Broad_Gauge|BG]]) ‘Indian Midland Section’ of the [[Great Indian Peninsula Railway]] (GIPR).

*At Dehli there was a connection laid from the GIPR mainline to a ‘Stone Yard’ where the material from Bari, and the other quarries was delivered, it was also dressed in this yard and the siding had a wagon repair workshop <ref name =darvill/>.

*The extent of the BG track was clearly extensive as shown by the number of wagons purchased by the [[Imperial Delhi Committee]] between 1913 and 1927. It is known that a BG locomotive shed existed at Barakhamba, which is adjacent to Connaught Circle in the centre of New Delhi and within a short distance of the GIPR mainline <ref name =darvill/>.

*It is also known that at the start of the project 25 miles(70km) of 2ft 6in/762mm [[Rail_gauge#Narrow_Gauge|NG]] line was in use. The NG line was used throughout the building works; the records show large amounts of track, locomotives, wagons and trucks being purchased from 1913-14 onwards <ref name =darvill/>.

*A 3 mile(5km) extension to the NG line was built in 1922-23 to brickfields, which were located near Safdarjang’s Tomb, which is 5km south-east of Connaught Circle <ref name =darvill/>.

*The extent of the NG tracks and the routes used during the building works is not known.
