'''Jubbulpore Gun Carriage Factory Monorail'''
The ordinance factory at [[Jubbulpore]] opened in 1904. Two different monorail systems were used during the construction of the site in 1901-02 in order to evaluate the ‘Calliet’ ‘[[Caillet System Monorail]]’ and the ‘Ewing’ monorail systems‘[[Ewing System Monorail]]’

The ‘Calliet’ system ‘[[Caillet System Monorail|Caillet System]]’ consisted of 10 miles(16km) of Calliet Caillet rail with six tip trucks, one log bogie and a platform truck to aid the construction of the Factory. The ‘Ewing’ system was ‘[[Ewing System Monorail|Ewing System]]’ ran from the the [[Great Indian Peninsula Railway]](GIPR) goods yard to the factory site, a distance of 2 miles(3.2km). The lines was operated using hand labour. As a consequence, the rates of cartage fell as competition to them increased but at peak times bullock carts were still used. On site the line divided one to storage area for incoming goods and one to the work area carrying rock and earth for levelling the site <ref name=Memo1903> British Library IOR/ L/MIL/7/14846 “Collection 335/13 Report on monorail tramway at Jubbulpore.”; Memorandum 11114; 1903</ref>.
The workers did not like the ‘[[Caillet system System Monorail|Caillet System]]’ wagons and found them difficult to handle. Trained operators were required and at least one bad accident occurred. The engineers found that a monorail was useful in these circumstances as it was quick and cheap to lay using unskilled labour. It would work with reasonably sharp curves and the rails did not have to be perfectly laid. There was minimum disruption to other road users <ref name=Memo1903/>.
The findings on the two systems were <ref name=Memo1903/>: -
The ‘Caillet’ ‘[[Caillet System Monorail|Caillet System Trucks]]’
<br>These were easier to control down slopes, but required trained labour and were wearisome to the pullers and therefore could be dangerous. They also found the same difficulties as experienced by the engineers at the [[Kundale Valley Light Railway| Kanan Davan Monorail]] . To change the type of motive power required rebuilding the connection frame and could not be formed into trains.
The ‘Ewing’ ‘[[Ewing System Monorail|Ewing System Trucks ]]’
<br>These were easier to use especially by untrained labour and could be joined together quickly. They found that the traction was heavier as a consequence and the large road wheel meant that loading could only be done from one side. These trucks hand not been used in the levelling works and it was doubtful how they would have performed on uneven ground.
The result of the trial, showed that the ‘Ewing’ system ‘[[Ewing System Monorail|Ewing System]]’ was the best and more trucks would have been ordered but the main line GIPR sidings had reached the factory. Major Edgell felt that a two-line light railway would have been best but the monorail was very flexible <ref name=Memo1903/> .
'''Jubbulpore Broad Gauge Sidings'''
<br>The records also show that broad gauge([[Rail_gauge#Broad_Gauge|BG]]) locomotives were allocated to the site from 1903 onwards, these would have connected to the GIPR sidings at [[Jubbulpore ]] <ref name =darvill/>.
