The '''Addis System Monorail''', also described as the '''Single Rail Tramway''' was a patented monorail system invented in 1869 by [[William Judson Addis]] ''(see separate page)''
==Background==
[[William Judson Addis]], was the engineer to the local funds committee in [[Thana|Tannah (later named Thana and now Thane)]], a fortress town on the island of Salsette, 21 miles(34km) north of Bombay. It was also the site of the first railway to open in India with the opening of the ‘Bombay (Boribunder) to Thana’ section of the [[Great Indian Peninsula Railway]] (GIPR) on 16 April, 1853 and the [[Tannah Viaduct]] which opened in 1854.
==History==
In 1869 Addis was granted a Patent <ref> UK Patent No 1850 Granted 14 January 1869</ref> for a tramway with a single rail on which ran a cart with two bearing wheels which take all, or nearly all, the weight; and ordinary wheels which serve to steady the machine and prevent over-turning. The cart, loaded with three tons, was easily drawn by two bullocks <ref name=Graces>[http://www.gracesguide.co.uk/images/1/13/Er18700617.pdf “The Engineer” 17 Jun 1870, page 377 (Graces Guide pdf 5))]; Retrieved 9 May 2017</ref>.
'''Tannah Iron Works Monorail'''
During 1869, in parallel with his Patent application, a demonstration line was constructed in the grounds of the Iron works at [[Thana|Tannah (later named Thana and now Thane)]], part of the line was laid at 1 in 40 incline with obstacles along the line and it had a 10ft radius curve. A pair of bullocks pulled 3 tons with ease and no mishaps <ref name=Graces/>.
'''Callian Bunder to Callian Monorail'''
'''Mhyjee Monorail'''
With this success in mind a further line was proposed from [[Maheji|Mhyjee (later named Maheji]] <ref>[http://dsal.uchicago.edu/reference/gazetteer/pager.html?objectid=DS405.1.I34_V17_014.gif "Imperial Gazetteer of India", v. 17, p. 8.]; Retrieved 9 May 2017</ref>) a station on the [[Great Indian Peninsula Railway ]](GIPR) to the site of the Mhyjee Fair a distance of 3½ miles from the station. Construction time 2 weeks <ref name=Graces/>. ''It may only have been for the fair and as a working demonstration.''
