Mumbai Monorail Dr.MeeraVasani IITRAM
Key Features • part of a major expansion of public transport in the city • 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 Bhd. • the first monorail in India since theKundala Valley Railway and Patiala State Monorail Trainways were closed in the 1920s.
Characteristics • Construction began in 2009 • The first operational line, between Wadala Depot and Chembur, was opened to the public on 2 February 2014. • Trains run from 7am to 3pm IST in the initial stage. • It is expected to operate for 19 hours straight by the end of March 2014.
Monorails are eco-friendly, can handle sharp curves much better than normal trains and metros, as well as climb up and down easily. Monorails also do not obstruct light since they are much narrower than normal rail tracks. The straddle-type monorail design (named so because the train straddles a steel or reinforced concrete beam) was adopted in Mumbai. According to the MMRDA, the bus service operating in the city plied crowded and narrow areas at very slow speeds, thus offering no benefits to the commuters and adding to the traffic congestion. The agency believed that an elevated monorail, that can take sharp turns, climb up and down easily, and run at an average speed of 30 km/hr and maximum speed of 80 km/hr would address these issues. The MMRDA also stated that the monorail would connect many parts of the city which were not connected by suburban rail system or the proposed metro rail system. The agency also stated that the monorail would be an efficient feeder transit to the metro and suburban rail systems offering efficient, safe, air-conditioned, comfortable and affordable public transport to commuters
Infrastructure • Rolling stock • The monorail cars were built in Malaysia by Scomi Engineering Bhd. • Each monorail train consists of 4 coaches having a combined passenger capacity of 568. • There are roughly 18 seated and 142 standing passengers at an average of seven persons per square metre per carriage (the end cars have a different capacity due to the driving position). • The low number of seats was to ensure that the flow of people in and out of the coach was not hampered.
Stations • The stations are situated at a minimum height of around 5.5 metres, higher in some locations, and can be accessed by staircases and escalators. • Each station has a total of four escalators - two from ground level to concourse, and two more from concourse to the platform. • All stations are equipped with baggage scanners, armed security guards at all stations entry points and CCTV cameras. • Personnel of the Maharashtra State Security Corporation (MSSC) are deployed at the stations.
Depot and control centre • The 6.5-hectare Wadala car depot provides parking facilities for 21 trains with an operation control centre, a training centre, a power station, a receiving traction substation and a full-fledged administrative facility. • Authorities can monitor the monorail's speed, signals, brakes, communication and safety from the control centre.
