INTRODUCTION

A monorail is a rail-based transportation system in which the track consists of a single rail, typically elevated and with the trains suspended from it.

The term is also used variously to describe the beam of the system, or the vehicles traveling on such a beam or track.

The term originates from joining mono (one) and rail (rail).

HISTORY The first monorail was made in Russia in 1820 by Ivan

Elmanov. The earliest patent was taken out by Henry Palmer in the UK

in 1821.

o Gyro monorails, balanced on top of a single rail, were tested, but never developed beyond the prototype stage.

One of the first systems put into practical use was that of French engineer Charles Lartigue, who built a monorail line in Ireland, which was opened in 1888 and closed in 1924 (due to damage from Ireland's Civil War).

Tokyo Monorail is the world's busiest monorail line, averages 127,000 passengers per day since 1964.

TYPES AND TECHNICAL ASPECTS

There are a number of competing designs divided into two broad classes, straddle-beam and suspended monorails.

Almost all modern monorails are powered by electric motors.

STRADDLE-BEAM TYPE SUSPENDED TYPE

The most common type of monorail in use today is the straddle-beam monorail, in which the train straddles a steel or reinforced concrete beam in the range of 2 to 3 feet (0.61 to 0.91 m) wide.

A rubber-tired carriage contacts the beam on the top and both sides for traction and to stabilize the vehicle.

MUMBAI MONORAIL

The Mumbai Monorail is a monorail system in the city of Mumbai .

The project was implemented by the Mumbai Metropolitan Region Development Authority (MMRDA), along with a consortium of Mumbai-based conglomerate Larsen & Toubro and the Malaysian infrastructure firm Scomi Engineering.

HISTORY OF MUMBAI MONO RAIL

On 18 August 2008 Vilasrao Deshmukh, Chief Minister of Maharashtra, approved the construction of a monorail system in Mumbai.

It was decided that the system would traverse through Jacob Circle, Wadala, Mahul, and Chembur, providing a feeder service to the existing Mumbai Suburban Railway.

The two shortlisted consortia to build the line were Bombardier Transportation/Reliance Energy, and Larsen and Toubro/Scomi engineering.

On 11 November 2008, Larsen and Toubro was announced, along with Malaysian partner Scomi, who received a 24.6 billion contract to build and operate the monorail until 2029.

A 108-metre test run was successfully conducted on 26 January 2010.

CONSTRUCTION

Construction of the Mumbai Monorail started in January 2009 along the Chembur – Wadala – Jacob Circle route and was scheduled to be completed in April 2011.

Due to delays, the deadline for operation of the first phase of the line, between Chembur and Wadala, was postponed to August 2012

The second portion, from Jacob Circle to Wadala, had been expected to be ready by December 2013.

The monorail had its test run on 18 February 2012 from its yard in Wadala to a station at Bhakti Park, a distance of around a kilometre.

The MMRDA invited proposals from agencies for securing, maintaining and leasing of bulk commercial advertisement rights to display advertisements.

The monorail cars for this service will be built in Malaysia by Scomi Engineering.

LAYOUT PLAN

OPERATIONS

The Mumbai Monorail was officially inaugurated on 1 February 2014 by the Chief Minister of Maharshtra. It became the first monorail system in India.

On 1 February 2014, at the time of inauguration the minimum fare on Line 1 was between 5 and 11.

According to studies conducted by the MMRDA during the monorail trial run, it was found that the monorail produces between 65 – 85 decibels of noise, significantly lower than the 95 decibel noise level of a Bus.

The monorail will have a top speed of 80 Kmph, an average speed of 65 Kmph.

The capacity of each four-car consist is 568 passangers.

There are roughly 18 seated and 124 standing passengers per carriage.

The MMRDA has stated that the monorail will operate in a single shift from between 7 am and 3 pm, for the first two months of operation.

Full-fledged operations of 19 hours, from 5am to midnight, are expected to start only by February 2015.

FEATURS

The Mumbai Monorail master plan proposed the construction of 8 lines at a cost of 202.96 billion.

Further development of the monorail system is on hold until the current line opens and none will be opened before 2019.
