In countries with advanced transport systems, governments embarked on the monorail project after
completing all other transport infrastructures such as metro and the bus fleet.

As a means of urban public transportation, monorails have been in use since the 1960's. Tokyo Monorail went into operation in 1964. A few years later, a monorail system was operational in California, in the Disneyland Theme Park. Over the last few years, a number of monorail systems have been planned and constructed; including Kuala Lumpur Monorail, Singapore Monorail, Orlando Disneyland Monorail and so on. More are presently being constructed for use in different parts of the world including the Tehran Monorail.
A monorail is an urban public transport system offering a number of advantages over other urban public transport systems (subway, bus, and so on). These advantages include: no noise, no vibration, no traffic disturbances and high safety standards.
Proven Technology
Monorails have significant advantages over light rail.
They do not interfere with surface traffic. Being elevated, monorails do not interfere with surface traffic.
The machine is environment friendly. Being electrically powered, monorails are non-polluting. Most run on rubber tires and are quiet.
Monorails are proven technology- they are proven people movers. Bombardier MVI monorails carry over 150,000 passengers per day at the Walt Disney World resort. Other companies such as Hitachi and others also produce medium to high capacity monorail transit systems.
Unlike light rail, monorails may be automated and may not require drivers. Light rail systems operate at a loss and require public subsidy money. A large portion of the operating expense must be paid to vehicle operators. Monorails offer the opportunity to become automated, thus eliminating this expense. In fact, many monorails such as the Tokyo and Seattle monorails turn a profit each year. Because light rail operates at surface level, light rail will never offer the option of being automated and therefore will always have to be subsidized by the taxpayer.
Heavy Costs
The idea to establish Iran's first monorail in the capital was proposed some 28 years ago by then mayor, Shahrestani.
Shahrestani eventually scrapped the project after consulting an expert team who advised against the plan, saying it would do least to solve Tehran's traffic dilemma.
Despite warnings by transport and traffic experts that the plan would create more problems in the mega city and that it needs further scientific backing, the present Tehran mayor Mahmoud Ahmadi-Nejhad is resolved to go ahead with the plan regardless of the heavy costs it would impose on the already cash-strapped government.
The bigger part of criticism is directed towards the plan's geographical mapping. According to those who have had access to the initial sketch, the selected route is less crowded, making the project, in their view, unjustifiable.
Among opponents of the plan is Ali-Asghar Ardakanian, a member of the Transport Engineering Society who says Iran lacks the required technology and knowledge to run and maintain the system.
Contrary to this are those who say the project falls within technological capacities of Iran. They are often heard saying that the Municipality and the Roads and Transportation Ministry have all the expert knowledge and manpower at hand to turn the project into a complete success.
Falls Short
Ardakanian insists the plan falls short of certain essential considerations such as failing to take into account the affiliated expenses for maintaining the monorail's underground and surface structures. The plan only encompasses the overall costs and this will cause financial austerities for the Municipality and the government, inevitably compelling them to cut down on the budget allocated for other transport sectors to keep the system running.
Supporters claim the project will progress more rapidly than other transport projects such as metro. They, says Ardakanian, have apparently failed to take notice that monorail's passengers transfer capacity is 10 times less than that of the subway.
He tried to drive the point home by saying that in countries with advanced transport systems, governments embarked on the monorail project after completing all other transport infrastructures such as metro and the bus fleet.
Monorail in these countries only complements an already established transport network.
The government should first complete construction of the metro network, as the city's main transport artery, and then take on more 'sophisticated' action plans.
Given the country's aging transport fleet badly in need of renovation, would a monorail not be an auxiliary rather than a necessity?
Moreover, experts are concerned that the plan will cause delay in implementation of other more important transport projects.
No Second Thoughts
All in all, the plan to establish Iran's first monorail was inaugurated on March 17. The line, about 12 km long, starts at Sadeghieh Square and forms a roundtrip path by extending through the Sadeghieh Metro Station, Ekbatan Township, and Mehrabad Airport Terminal.
The project was reportedly inaugurated without receiving the approval of the High Traffic Council; a body in charge of studying and approving transport schemes.
The Municipality's failure to win the council's approval will disqualify it from any form of state assistance.
The plan is estimated to cost 800 billion rials, with all the necessary equipment and parts to be imported. Nowhere in the world has a project cost $12 million per kilometer.
Would the municipal body be willing to give the plan a second thought and instead put the focus on extending the metro line and renovating the dilapidated bus fleet to provide the people with easy and cheap access to a well-functioning public transport system?
According to most experts, the monorail plan lacks economic, technical and financial justification.
