Addis System Monorail
William Judson Addis, was the engineer to the local funds committee in 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.
In 1869 Addis was granted a Patent [1] 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 [2].
In 1870 a further Patent was granted concerning improvements to the track system [3].
The advantage was the cost of the tramway with the haulage cost reduced to a minimum. The rails were laid at the each side of roads leaving the centre part for ordinary traffic; as the rails are only 1½ -2 inches(3-5cm) above the surface of the road they would scarcely interfere with ordinary traffic [2].
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 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 [2].
Callian Bunder to Callian Monorail
A line 1¼ miles(2km) long was built to carry salt to Callian (later named Kalyan) from Callian Bunder. The motive power was again Bullocks. The line opened on the 22nd January 1870. The line was successful with two bullocks pulling 2½ tons the full length in 19 minutes. How long it lasted is unknown [2].
Mhyjee Monorail
With this success in mind a further line was proposed from Mhyjee (later named Maheji) a station on the Great Indian Peninsula Railway (GIPR) to th esite of the Mhyjee Fair a distance of 3½ miles from the station. Construction time 2 weeks. It may only have been for the fair and as a working demonstration. [2]
